What is Reddit's opinion of
PhotoRec?
From 3.5 billion Reddit comments
100 reviews of this app found across Reddit:
If they're just simply deleting photos then it would be a very easy task to "undelete" those photos later (provided they are not using more sophisticated methods of deletion). There's plenty of software available for the job. I'd recommend Photorec. Did you ever give something like that a go?
This is why it's important to know how to recover "deleted" photos and video, if you're using a standalone camera where you can pull the SD card (or similar storage media).
As soon as you delete your previous data, swap the media for a fresh one and quarantine the one where you deleted stuff. When you get to somewhere else, use PhotoRec or whatever recovery software you have chosen to attempt to rescue the "deleted" material.
Rehearse this scenario before it happens to you for real. Carry that spare SD card.
(Also, it can be useful to zero-fill your cards between uses, so you don't have to wade through "good-deleted" old material to find the "bad-deleted" stuff that you want to get back.)
You can use a tool like photorec that can recover many multimedia files from ext2/ext3/ext4.
If the files were any of this huge list of formats it's likely to be able to recover them.
GNU ddrescue is even better.
https://askubuntu.com/questions/211578/whats-the-difference-between-ddrescue-gddrescue-and-dd-rescue
And then the recovery app to try is PhotoRec.
Next time you accidentally format a card, take the card from your camera, slide on the write protect tab if it has one, and put is safely away. DO NOT USE IT IN ANY WAY UNTIL YOU ARE HOME! Use your spare card (you have one, don't you?) to take pictures.
When home, download PhotoRec and use it to recover the photo's on the card. If you are not comfortable using command line utilities ask a friend who is. If all else fails, you can even try /r/linux to bribe a friendly redditor nearby who's willing to help in exchange for a meal or a good beer or stuff.
It happened to me as well. I kept the card safe, and recovered all but one picture of the 500 pictures on the card. Within one hour.
(Edit: I have more than 35 years of experience with computers. My first computer had 256 bytes of memory. This reptile has seen it all. Yes, I know there are commercial programs to recover data from flash cards, some are even user-friendly. However, PhotoRec is free, is actively supported, recognises odd image formats like most RAW image formats, video, stupid shit with hidden folders used by some manufacturers. Use it, see if it works, and then donate what you would have spend on ShittyPhotoUndelete v11.3.2.1 Pay for succes, not for the expectation of success.)
I've got an Eye-Fi card and they're pretty clever.
Being familiar with how to un-delete is even more valuable though, as it can't be spotted by examining the basic hardware and doesn't need any special hardware.
If you're expecting to need to undelete, I suggest blank-wiping your SD cards between uses (I use the free Disk Redactor), so that the recovery tools (I use PhotoRec) don't find the ghosts of your old photos which are already safely offloaded at home.
edit to add: as soon as you've been coerced in to deleting a photo you want to rescue, switch SD card - to reduce the risk of the deleted file being overwritten.
- Stop using your phone immediately. Turn it off. The more you use it, the more data will be overwritten.
- If your photos are on a removeable SD card, it should be pretty easy to plug it into your PC and run a program like Recuva or photorec (more complicated). If you do this right, you have almost 100% chance of recovering everything that has not yet been overwritten by you using the phone afterward.
- If they are on internal storage, this is a lot more complicated. You will either need root, and put a recovery program on your phone, like photorec or Undeleted (have not tested this one). Otherwise enable mass storage mode if you can and run the programs mentioned above on your computer. Both of these methods are not so great because you can't really set your storage to read only in android, so you will overwrite part of your data. If you can't do either, you are probably fucked. If this is too complex for you, try asking someone with technical knowlege about android / linux.
And I hope you learned your lesson about not clearing Trash for no reason. It also should have warned you about exactly this happening.
You very likely still have lots of those photos unless you have used that card a lot since then. Formatting doesn't actually do anything aside from designate that data as being able to write over. Go here http://www.cgsecurity.org/wiki/PhotoRec this is really awesome free software - you have to use terminal but it is very self explanatory if you have some computer experience. The first time I tried it I found photos from 4 months prior on my card!
Most importantly: don't use that drive at all, for now. The more it's left alone, the less chance there is of the files' data being overwritten. Only boot off a DVD or external drive.
Once the drive is safe from being overwritten, you might consider trying PhotoRec, a free file recovery utility. Its original goal was rescuing photos from camera SD Cards, but it's aware of many other file formats beyond RAW, JPEG, and the like, including PSD.
It does tend to be quite effective, but, the recovered files may well be renamed to alphabet soup - but presumably, that's less of a concern than losing the files themselves.
It is, unfortunately, quite a geek-oriented tool. Their guide is fairly complete, but is aimed at a fairly techie audience.
SERIOUSLY! THIS! It doesn't need fancy equipment, a USB card reader will recover photos.
If you have a USB Card Reader and the files are saved to a card not the phone itself the following program will "undelete" them - I do it for customers all the time.
http://www.cgsecurity.org/wiki/PhotoRec
EXTREMELY SIMPLIFIED
This works because hard drives work like a book - you have the actual pages that you read and the index in the front.
When you are deleting files, almost all the time all you are doing is removing that file from the "index".
The chapter is still in the book, it just isn't listed in the index.
Things like Windows Explorer only shows you a fancy version of the index and only opens files that are mentioned in the index.
When you add a new file, your computer finds the space in the index and puts your new data there - it may be over the top of old files, it may be in a space - it doesn't matter to the computer because it knows if a file isn't in the index it has been permanently deleted. Until that point 100% of the file still exists, it just isn't listed in the index.
The program listed above creates its own index from the files it finds.
The reason you need the USB card reader is because a lot of devices do not let you access them directly, they give your computer the index list and only serve up files on that list.
This works with cameras as well as phones of course.
Edit: Replaced tech jargon with book analogy.
Firstly Take the SD card out and do not write anything to it! Deleted data remains there until overwritten, if it hasn't been overwritten it will be easy to recover.
Find someone with a computer that knows what they are doing. This program is very good and is made for the problem you have, to recover lost photos. http://www.cgsecurity.org/wiki/PhotoRec It's probably not easy to use for someone that doesn't know much but it is a very good program. Another I have used was PC file inspector. Also if the photo's are valuable enough to you pay someone to do it for you who knows what they are doing rather than just guessing and ruining any chance of recovery.
I have had a lot of luck with the free PhotoRec but any of the others will do really. The key thing is to stop using your card. Even if you have used it a bit, you should still be able to get most of the things back but the sooner you stop using it the better.
Just for future reference - the standard program for this sort of thing is Photorec. It comes together with Testdisk, which would probably have restored the deleted filesystem, complete with folder and filenames.
If the data was on a removable memory card (microsd):
- Turn phone off, remove card. Isolate it. (To ensure nothing gets written to the "empty space" where the files are)
- Put card in card-reader attached to PC, use PhotoRec to see if you can recover the goodies.
This also applies to regular digital cameras. There are other recovery tools but of the free ones I've tried, PhotoRec has given me best results.
YES. Don't use the drive anymore.
http://www.cgsecurity.org/wiki/PhotoRec
1.Mount the drive
2.Read the instructions
3.Perform data recovery
PS. I've used it on a corrupted sd and recovered 100% of my data. Just let it do its job.It may run for hours depending on your hdd size.
PS2. Feel free to ask "how to" questions
I haven’t read through all the comments, but you could try testdisk to recover some, if not all the deleted files. I mainly used it to recover partitions and it worked perfectly.
There is also photorec from the same developers in case the files were incredibly important and testdisk wasn’t able to find them. Be careful with photorec, though. It will spew out every possible file it finds. I ran it for a few minutes after my laptop overheated and shutdown while I was writing something and quickly found ~20GB of useless data chucked into folders (no directory structure or anything), each containing some hundreds of files found by photorec. When I say useless, I mean thumbnails, cookies, partial screenshots of what I was doing online(only from Edge. Thanks MS. ), misread files (mp3s and oggs that were nothing but static noise. Absolutely nothing discernible) and the likes. But it also found parts of the files I needed
Ignore all the non-tech savvy people here.
If you haven't done anything yet, your data is easily recoverable.
Disconnect the drive if possible. If you are able to disconnect, put it in an external HDD reader on another device so you can mount it as another "data" hard drive vs your computer recognizing it and automatically using it. Don't shut down or turn off your computer unless you are removing the disk. That way you have a lower chance of overwriting data. If you can't do that, just don't do anything until we all figure out what partition you deleted. It's unlikely there will be data written to where your partition was, as Windows thinks it is just empty space and will ignore it.
Step one is to use testdisk to try to recover your partition. Your partition is still there, Windows just thinks it isn't anymore. If it works, your partition tables will be restored. There might be some data loss if you already tried to make another partition where it was.
If step 1 failed, try to get your important and valuable files out of there using photorec and copy it to an external drive or somewhere else.
Make an image of the drive using dd. In that case you do not have to use the card and destroy it on accident.
You can use Photorec for trying to recover your data. Might work and save you a lot of time.
Photorec. http://www.cgsecurity.org/wiki/PhotoRec
I know everyone's go to recovery method is recuva but I have actually had much more success when photorec. I've had multiple instances where recuva was unable to grab anything only to recover multiple files and photos using testdisk/photorec
First of all set the card to "read only" to protect further damage to the files on the card. That is the little slider on the side of the card. I have had good luck with recuva, https://www.piriform.com/recuva
PhotoRec is also free and has good reviews, though I have not tried it yet http://www.cgsecurity.org/wiki/PhotoRec
Good Luck!
After it was formatted? Absolutely yes. The data is still there. PhotoRec would get it back for you.
But if the card has already been filled again the data is gone forever. However if time is indeed cyclical you can retrieve the data with the next interaction of the universe.
I'm not the person you asked, but just in case anyone reading this is a Linux user, I've used photorec on Linux on both sd cards and a dying, wouldn't mount hd and recover files.
If you realy want to recover something you should disconnect hard disk and do nothing with it. Install programs on other or boot from recovery cd. Every program you install, even browsing (page history,temp files) overwrites some parts of disk and makes it unrecoverable.
I had some success with http://www.cgsecurity.org/wiki/PhotoRec but in no way it recovered everything ...
Right.. But lots of things can be done yourself. I've recovered loads of data with freely available and cheap software. As I say, very rarely is the data a total loss unless there is actual hardware damage.
If you have the drives still, ddrescue them to new drives/images using this tutorial and the knoppix live cd:
http://forensicswiki.org/wiki/Ddrescue
Then working on the clones, try things like photorec http://www.cgsecurity.org/wiki/PhotoRec
And recuva https://www.piriform.com/recuva
Which are all free.
Join us at /r/datarecovery if you need assistance.
Even if you could get the program to launch in wine, it still wouldn't be able to recover any files. Windows normally uses ntfs as the filesystem, most desktop Linux distributions will be using ext4.
If you are looking to recover some files from a Linux partition, I would reccomend http://www.cgsecurity.org/wiki/PhotoRec, I've had success with it in the past. It runs on Windows AND Linux, and supports the most common fs's.
If you didn't fill up your drive with new datas, your old files may be recoverable. PhotoRec can recover files after disk formatting. You will find it in the ubuntu repos.
To maximize recovery chances, I would plug the drive on another computer and perform a search with photorec. This can be long, and it will recover all previous files. Folders and filenames will not be recovered.
Just a small PSA: files deleted with your regular file managers can be easily restored using apps such as photorec. I would be careful with that phone and its memory card.
This is unacceptable behavior- please do yourself a favor and cut her from your life.
I'd like to recommend you an excellent, open source disk recovery software that I've used many times. It can recover photos on Windows, Mac, and Linux: PhotoRec/TestDisk. It won't recover filenames but it gets the contents.
I was able to recover tons of lost files for a friend with this package. The package has photo in the name but it recovers a lot of different file types- I got all of my friends mp3s back with it. Good luck!
Also, you should change your password and not share it.
All hope is not lost, there is a chance that some data can be recovered.
This is how the ransomware process works:
When infected, the cryptographic process phones home, decides on a random encryption key, and begins encrypting files. File encryption isn't a destructive process, encrypting a file means reading the unencrypted file and writing an encrypted copy. The malware process then generally deletes the unencrypted copy.
The System Restore service on Windows also keeps snapshots of file changes, and the virus will attempt to remove previous restore points to try and prevent you from recovering files through these snapshots.
So here are your two options, aside from paying the ransom:
Download this program called Shadow Explorer: http://www.shadowexplorer.com/downloads.html
It will allow you to access the snapshots and possibly recover the files without paying.
The other option is to use something like photorec on the flash drive to try and recover the deleted non-encrypted files.
If your GF was using dropbox or Google Drive, they can roll back the changes as well.
If you want help with any of this, let me know. I own a small computer repair shop and deal with this exact scenario from time to time.
If you need to do some data recovery and the drive is giving up the ghost use photorec from cgsecurity. We run it on a debian box and is installed with the testdisk package. The bad thing about it is that it spits out almost random files so its nice to sort them. I made a sorter to do so. It works off of python 3. As long as the drive is connected it can get data.
Maybe a lab with something like teaching them how to use PhotoRec?
- They'd have to install a package
- Locate and unmount a device
- Run a program with root or sudo
I think I've amazed and thrilled more people by saving their lost photos than with any other Linux related skill.
Edit: More thoughts
If you don't have enough SD cards or small USB sticks, you could provide an image of the SD card already on their computers.
The photos/files they recover could be something linuxy like a picture of tux, or something silly like a Rick Astley video or something.
OK OP, you need to do a couple things right away.
Stop using the computer and that SD card right the fuck now. Especially the SD card since that's your best shot at this.
Get another computer with a storage device big enough to hold the entire SD card's contents. External HDD, internal, either works. Just not the Mac you were using if possible.
Download PhotoRec and run it on the computer with the now-empty SD card mounted.
Make sure you do not let it save back to the SD card. Save it to that separate storage device identified above.
Let it work. It will take a long time especially if you enable the brute force options in PhotoRec.
Review your rescued photos. Hopefully be a hero.
> when the reality is it's still there. That's how you can still recover data, granted you haven't overwritten it.
BINGO.
I took care of not editing a thing, and using the appropriate tool. Recuva didn't find the device as it wasn't mounted (corrupted). So I used "Find and mount" (LINK), and mounted the flashdrive into a virtual partition "O:". Then I used "TestDisk/PhotoRec" (LINK) to recover the files.
Amazingly, it recovered almost ALL the files I had (aprox. 3.2 GB of data). Of course I had everything backed up on my HDD, as I use the flashdrive as a portable apps device.
TL;DR: Didn't modify a file, mounted on virtual partition, recovered all data. STRONGLY recommend Photorec!
I'd look into TestDisk, a nice little free app that should be able to get back the partition on your drive, assuming you haven't started using it. There's also PhotoRec from the same people that will scan the whole disk and rescue files from the void based on signatures of known file types. I know PhotoRec sounds like it's only for Pictures, but it does all kinds of stuff.
This is the software to get, and it is free. You also need photorec. Testdisk will recover a partition, and photorec will recover the photos from the partition.
Since you stated that none of them are booting and none are backed up - it all depends on how far it got. If it had just deleted the partition from the table and didn't progress further, you might be able to use TestDisk to recover the partition. If that doesn't work your only other option would be to try and use a tool like PhotoRec to recover what bits it can pick out from the drives. Though doing this at that volume of machines - I'd probably go insane.
Just remember at this point if you want any chance of recovering anything, you need to make sure whatever you try doesn't write to the drive at all.
Keep the clone of the phone and never write over it using any recovery software - that is make sure the recovery software reads only and doesn't attempt to change the clone. It can write undeleted/repaired files elsewhere.
I have had luck doing similar things with photorec.
photorec - although its a command line program.
Always successful for me, but it does rename the files (you can probably tell it not to, but I've no idea how).
There's this Linux program called PhotoRec you can try.
By all means, do not try to repartition the drive, or do any kind of writes to it. You'll be overwriting your data.
First: Stop working on the drive and create a raw disk image using a live-cd.
You need to "carve" the keys from the image created above using some recovery software. Read this article where the author uses scalpel. You might have luck with PhotoRec too - It's "interface" is a bit easier.
Please note that your Ubuntu installation could have overwritten the location of your keys - This will only work if no parts of the keys have been overwritten.
That does look pretty bad if the files have been severely corrupted. My only recommendation is to use a utility called "photo rec"
http://www.cgsecurity.org/wiki/PhotoRec
This is an awesome tool that recovers deleted files off of a drive indiscretionately and i have had tons of luck with it with lost or damaged partitions in my shop... however if they are the original files and corrupted i doubt even a data recovery tech could help.
Good Luck!
Use PhotoRec. Excellent program. If it can't find them, they are unfortunately lost.
Try PhotoRec. It's free (and open-source), and can work pretty well. It's not easy to use, but there are instructions on the site on how to use it.
Perhaps obvious, but: do not write anything to the card, take more pictures, etc. until you're done attempting to recover whatever was deleted.
I give PhotoRec a solid recommendation. I've never used it on an old cd (though I've read that people have), but I have used it on dying hard drives and old sd cards and it has been more successful both times than I imagined it would. One of the hard drives would not even mount on any computer I had.
You'd save everyone else a bunch of time by naming the 20 you tried.
Best not free: Handy Recovery
Emergency/rescue-CD stuff:
- HawkPE, and Hiren's Boot CD — Two illegal alternatives to UBCD (swiss-army knife boot utilities). Because they have pirated apps, I don't use them at work unless I really have to, but keep them in the back of your drawer, because they're invaluable in a pinch.
- several anti-virus boot CDs — these run outside the infected system, and so aren't affected by rootkits or other nastiness
- photorec (recover deleted files) and testdisk (recover deleted partitions)
Used this the other day to recover photos of my friends 2 year old son's birthday party. Was an awesome Valentine's day present to his wife as she was freaking out thinking they were gone forever. PhotoRec I assume is a more media oriented (stripped down version of Testdisk).
I recently deleted all the photos on my SD Card by mistake (hit "All Frames" instead of "This Frame" somehow and didn't realize until after hitting confirm). I ended up recovering all of the photos I deleted about 24 hours later using this opensource software: http://www.cgsecurity.org/wiki/PhotoRec
It's a tiny bit confusing to use as it doesn't have a UI and is only based in the command line, but it was flawless for me (in fact, it recovered too much, bringing back stuff I had deleted over two months prior). Not sure if it will work in your situation, but figured I'd provide that link.
Here's an open-source (free) application that I swear by. It is a command prompt based program, but it works like a charm. I do suggest that you use a USB Thumb Drive as the recovery folder for the erased items. If you need help using it, let me know. http://www.cgsecurity.org/wiki/PhotoRec
Also, if there's not many photos on there, try a photo recovery tool to get deleted photos. http://www.cgsecurity.org/wiki/PhotoRec This might give you a higher sample of images to help ID the owner by.
You can't mount the drive directly. If lvm can still find/assemble it (hopefully you had a mirror rather than concatenation), the logical volume would have a name like /dev/mapper/* or /dev/vg*/* which you can try to mount.
It'd be helpful to see the output of vgscan, vgdisplay, lvdisplay, and pvdisplay.
A last resort would be to use something like PhotoRec to scan every sector and restore known filetypes to an external drive. You'll lose filenames/structure, and it'll find a lot of files you don't care about it (like from your browser cache).
Assuming you didn't securely delete (overwrite the files) then you should be able to run a file recovery program. However if you do use one of these recovery programs it will recover a bunch of shit that you have deleted in the past so you're gonna be sifting through a lot of stuff to find the images that you are looking for.
If you're using Windows use: Recuva If on Mac or Linux use: PhotoRec
Let me know if this helps!
If that customer data is worth up to several thousand dollars (USD) or more, just go to the pros.
You should stop using the drive (no power at all) until you are ready to start the rescue.
Removing the drive is pretty easy, just disconnect and reconnect. Installing a GPU is harder.
Get into a *nix based OS from usb with the two hard drives (original and destination) attached. Identify what drive is which (/dev/sda, /dev/sdb, etc), then
ddrescue /dev/sda /dev/sdb LOGFILE_LOCATION
It will run for a while. It can be interrupted as long as when you restart it you point it to the logfile you used.
Once it is done, use photorec to scan the rescued data for the files you want.
Optionally, you can clone the rescue (using regular dd) onto another drive to see if you can just boot from it. It will be doubtful.
Put your SD card directly in a card reader (don't do it through your camera -- if you are). Then see if you can get the photos. If you still can't, get PhotoRec (the best photo/file recovery software I've used -- interface is a little weak, but it's pretty easy to work through).
Cheesecake to save the day!
You're not at all royally fucked :D
It so happens that in this case, you should have everything still on the disk. There are a variety of recovery options of varying difficulty and results!
(Disclaimer: It's possible some files are gone, but the vast majority are still there.)
My go to for basic recovery on small partitions: PhotoRec
It's a command line scanner, however it's incapable of returning lost files with their original header (the free version) so you'd have to go digging around in what it finds to find your lost, important files. This is a big problem on large partitions, as it has to have space to copy the files to, and looking through thousands of files with "000100010" as the title, can be quite aggravating.
NUMBER TWO! FTK Imager FTK Imager is a free version of the AcessData Forensic Toolkit. It's incredibly stripped down, however it will still allow you to identify and recover the files still left in free space on the drive.
These are the only two tools I'd recommend someone in your position try first; if you need any help please feel free to message me.
I've been in your position before, and hoooo boy does it suck. Lucky you modern technology is awesome.
This may help:
http://www.cgsecurity.org/wiki/PhotoRec
No guarantee though. And for the record, I've never had an issue with SanDisk cards themselves, it's just pretty much all SD cards can have issues from time to time.
I don't know of any way to fix the messed up images, but I've had great success with PhotoRec for recovering files from a deleted/reformatted hard drive. That might work for getting the images back off the old drive, but it will take a little work. Also you should be comfortable poking around in DOS.
If you need some more specific help, give me a shout.
If they're all getting the same results, likely issue is bad sectors. The data that was on those sectors are no longer there, likely, because the sector is not readable. It also, sometimes and not often, it just may take a few more trys for a sector to be read before it'll work again correctly and return a result. Some forensic software isn't designed to keep trying to read a sector, some of them and I wish I knew exactly which ones will only make a fee attempts to read it and move on. The rapidspar, which I happen to have, does just this. It'll dig into sectors and keep digging, but I'm unaware of the results of what happens when sectors are tried over and over again to be read, I'm assuming they'll fail eventually and the data there is lost forever.
There is a open source software out there for photo recovery. I believe it'll carve out what's needed to get it done. Others here have used, I believe, but I have not needed it yet, thankfully. Try this
If it doesn't work, PM me and I'll be curious to see if my rapidspar would be able to help you out.
Good luck.
You might be able to find them back with Photorec. Don't write any data to the drive you want to recover, everything written to it has a chance of overwriting things that could have been recovered.
You can try GetDataBack, it should have a wizard for this scenario, but most people find it quite expensive (professional recovery costs 10 times as much, so I don't think it's actually expensive).
You can also try Photorec, but it won't recover the metadata like directory structures and filenames, only file contents.
Also, the first ~4 GB of files will be unrecoverable.
Linux. More specifically Testdisk with PhotoRec:
http://www.cgsecurity.org/wiki/PhotoRec
http://www.cgsecurity.org/wiki/PhotoRec_Step_By_Step
https://help.ubuntu.com/community/DataRecovery#Photorec
Don't have ready access to a Linux system? A Live USB might be a good way to go.
(I can expand on this in a little while).
An app called photorec will probably save your butt.
Basically the files are probably still there, just the records of how to locate them need rebuilding.
Photorec sounds like it's for photos I know but it pretty much recovers any files that are there to be found.
DON'T COPY ANYTHING TO THE SD CARD. The data is very likely still on the disk but deleting them basically clears their entry in the filesystem table, allowing that data to be overwritten.
PhotoRec is my favorite tool for recovering specific file types off a damaged file system. You basically run the exe, select the drive, and let it run. There's a step-by-step on the page I linked.
The first thing you need is somewhere else to put those files. If you don't have a suitable sized USB drive or whatever, stop what you're doing until you do.
Someone else said this but I will reiterate - if you have the option, get a drive that's the same size or bigger than the one you're working on, and create a clone of it. Then you can try whatever you want on the clone - if you screw up you can re-clone it from the original.
Honestly if the data is irreplaceable, worth enough to you, and you feel you're well out of your depth you may want to look at hiring a data recovery specialist. If it's just photos you're interested in, you may have some luck with PhotoRec.
Any strange hard drive noise occurring at regular intervals is almost certainly a sign of impending hard drive failure.
Honestly, I'd say turn off your computer, buy another hard drive of a different model, and copy over all your data to it ASAP once you receive it to minimize the risk of data loss. But if you don't want to spend money on that, since it's unlikely that both are failing at once based on the noise pattern you're hearing, you could try doing something like using CrystalDiskInfo to identify which drive is failing, then copy over anything you need to save to your other drive.
It's quite possible that your data has already been corrupted, so be sure to check your photos/music/documents/ZIPs/etc. afterwards.
e: Using TestDisk or PhotoRec from a flash drive or CD to mount your failing drive in read-only mode can help restore any files you can no longer find due to file system damage. Be sure to consult the FAQs and step-by-steps at the bottom of the wiki pages first if you decide to do so.
Before you read my idea I want to mention that professional data recovery services do exist. Depending on exactly what is going on with your SD card, information I cannot ascertain from your post, there can be some degree of risk of losing data involved in trying to recover data. You can expect that a professional data recovery service would hopefully be able to minimize some of these risks.
Hmm, it sounds like you already have pulled the data off of the SD card but I think it might be potentially useful to consider pulling the data off again with PhotoRec. PhotoRec may be able to get more complete files off. Note that if it works, generally the file names will be absent and that doesn't mean the files aren't intact. Be sure to actually open the recovered photos.
download (I know it says TestDisk but this is the correct download page.)
PhotoRec is a program that runs in a Terminal like window. It doesn't have a friendly user interface. If you are having a lot of trouble getting it to run you can post a screenshot or pm one and I might be able to help.
One other thought would be to see if you can figure out what format your the camera that originally wrote the photos to the SD card would write them as. A lot of raw image formats are not going to be something you can open with Preview.
Download PhotoRec. It comes with TestDisk. It recovers data based on file header and will recover anything that is there to recover. The latest versions even have a GUI interface, if you don't want to go the command line route.
If you scan the free space on the card with PhotoRec and don't recover anything, I'd say you are likely out of luck.
The great thing about PhotoRec is that it is thorough and free. Only downside is that you won't retain the directory structure or file names.
Also, if you are able, best practices for data recovery advise making a clone of the card so you have a backup. You can clone it with free software like ddrescue or FTK Imager.
Good luck!
It doesn't. If data is overwritten or really wiped (not quick formatted), then it's gone*. If you quick formatted a drive and then wrote some data to it, then you may be able to recover some old data with for instance PhotoRec.
*. There are some hypothetical ways to recover the data by reading the platter with an electron microscope. I know only one paper describing this process that actually tried it for real, while some bits were indeed recoverable, it wasn't even possible to reliable reconstruct series of bytes, let alone whole files.
Photorec can sometimes recover deleted files. The delete command does not in general zero the data, it just removes the references to the data from the filesystem. If you have not written anything else to the partition that the files were on, then there is a chance the data is still there untouched. Photorec scans the 'empty' space on the disk, looking for data that looks like an old file.
I recommend that you get hold a large external disk, boot from a live cd, install photorec in the live session, and try to recover from the partition were the files were stored onto the external disk.
its possible that the card still has the data and maybe the fat table or something on the card was corrupted, I use a program called photorec to recover photos from SD cards I think it will restore any kind of file so you could recover it on a PC then put the save file on a new card

Some background, along with what I think happened.
- Drives have to be formatted before they can be used.
- There's various types of "formats", also called filesystems. Each format has specific advantages and limitations.
- The type of computer (Windows, Mac) has to know how to read/write that format.
- Windows knows FAT32, exFAT, and NTFS. Mac knows HFS and exFAT.
- If you plug in a flash drive where the computer does not know the format, or filesystem, it will usually think it's corrupted and offer to format it for you.
- This is probably what happened on the Mac, a prompt probably appeared asking to prepare or format it and "Yes" was clicked.
- So now your drive is probably formatted to HFS and Windows doesn't know about it, so Windows now wants to format it.
Can you get data back from it? Possibly.
DO NOT WRITE ANY MORE DATA ON IT. Your file might still be there in space now marked as free on the drive (formatting doesn't physically erase the entire drive, but it does create a new blank "file table" of information that's pointing to files on the drive).
Download PhotoRec and let it scan the drive, and see if it can hopefully find your spreadsheet. Good luck.
There's a pretty good chance most of it can be recovered.
Try the program GetDataBack for NTFS. I've had great success with it in the past. There's a trial version so you can see if it finds your data, but if it works you'll need to pay for it to recover the files and partitions.
There are several free alternatives like TeskDisk or PhotoRec, but I don't have any experience with those at all, so I can't really help you more than that.
Fixing it may not be possible, but you might be able to recover the data on the drive. I personally like PhotoRec (http://www.cgsecurity.org/wiki/PhotoRec) and have had it successfully recover documents from a bad 2gb flash drive. That being said there is no guarantee that you can retrieve the data. Flash memory is very finicky and I would recommend backing up often. The reason it is "RAW" is because the file system has become damaged and is not recognizable.
tl;dr Use a file recovery tool to get your data, then format the drive because the file system is damaged.
You don't have to as you can recover the images from your memory card using free software. You just have to make sure you don't record anything else on it before recovering it. When you delete something you don't actually get rid of it, you just remove the file system, but the underlying data is still there (so the photos or files).
Here's the wikipedia entry on the software to verify it's not a trojan or anything dodgy- I've used it before after stuff being deleted by accident and it worked perfectly (both photos and video).
Congratulations, you just learned Rule #1 in Data Recovery: If you get access, copy the data because you may never get access again.
Try Testdisk and PhotoRec. If anything short of a data recovery lab can get the data it's these.
>it'd be like 900 dollars at best buy
And that's while you avoid Best Buy like the plague, lousy service at a high price.
Western Digital and I believe Seagate have data recovery services.
Last, whatever the outcome, setup a backup strategy so it doesn't happen again.
I'm honestly not sure if this works for a CD, but I've had important pin drives go bad on me.
dd copy it to an image file, so you don't have to worry about making things worse. Then try PhotoRec on it. It does file carving, so as long as it can find something that looks like an excel doc/photo/etc file header, it'll try to recover it. It worked for us.
Removing files/directories via the terminal deallocates them from memory directly. I've had some luck searching for deleted files on hard drives & flash drives using PhotoRec/TestDisk (http://www.cgsecurity.org/wiki/PhotoRec).
well if you havent touched the sd card since you deleted it you may be able to recover using some recovery software
I dunno which one is good but this one I found on google
Eesh, this is not going to be pretty for you. You could try using something like PhotoRec to pull the data off the flash drives, but I can't guarantee which files it'll save. Worse yet, it probably wouldn't preserve the file structure. It may not even preserve file names.
You might have to shell out money and hire a data forensics professional, and when I say "money" I mean "great big heaping piles of cash."
To get the best odds possible of recovering any data that card must not be written to between now and whenever you get it. CF Cards work a little differently than a hard disk, but the data may yet live in the little NAND chips.
Hello,
In addition to Photorec, which [Auriem](/u/auriem) recommend, I'd also suggest looking at Runtime Software's GetDataBack line. They are not free, but you can at least download and run a trial version that will let you know if it finds anything before you purchase. I have had good results with it over the years.

There is hope, if the files are very valuable to you i would suggest stopping fucking around with it and send it here : http://datarecovery.lc-tech.com/
If you don't want to pay to recover files this is the program to use : http://www.cgsecurity.org/wiki/PhotoRec
Do you know if the files were corrupted before you moved them? Were you ever able to view them correctly on the external hard drive? Image recovery/repair programs are usually built to recover the original, uncorrupted files from a corrupted CF/SD card. You could certainly try running a recovery program on the hard drive itself, but I don't know how well it would work. A good command line program I've used is http://www.cgsecurity.org/wiki/PhotoRec. Transcend offers RecoveRx, though I don't know if it works beyond CF cards: http://www.transcend-info.com/Support/Software-4/
Scan it with PhotoRec http://www.cgsecurity.org/wiki/PhotoRec. It looks at raw file data at a drive level and can recover a lot more partial files than Recuva or consumer file recovery. Don't be fooled by the name, it's tuned to recover many common file formats.
This? http://www.cgsecurity.org/wiki/PhotoRec or this? https://www.piriform.com/recuva
One thing is though, because of the nature of the way the filesystems work, the more use a drive has been put to, the less likely the chances of successfully recovering a file.
And, the outputs of these kinds of things are usually quite a mess, with a lot of itty-bitty seemingly randomly named files that have to be gone through by hand. Some will be intact and open, others will not, and there is no way to automate the process I know of. You can get some (a lot) of data back, but you still have to sift through the trash by hand to find yer gems.
Good luck. Yer hunting or a diamond in a landfill ....... but that doesn't always mean there is nothing present but garbage.
There are some data recovery programs you can use to hunt out the file, it's not totally gone until it gets zeroed out.
I recommend PhotoRec, i've recovered video files off of supposedly "clean" SxS card before using it.
You should be able to use photorec to recover photos from your SDCard. It will carve out any pictures it can find, you might have some you've deleted on purpose and some that are corrupt, but you should get most if not all back.
> Replace Windows 7 with Ubuntu"
This has happen to me before!! Thank god i recovered it but it was a painstaking process, all the photos were recovered and few of the files were corrupted in the process, but all in all, it saved my ass.
Consider this a motivation for photographers to always know their rights.
That said, if your goal is to just avoid conflict (usually it's just easier), just delete the picture, change the storage card, and later retrieve it with Photorec. The whole "delete this photo" thing is totally pointless.
PhotoRec has worked quite well for me recovering pictures. if the files have been corrupted they may or may not be salvageable. It's a simple command line/promt program and is fairly easy to use.
I remember when USB thubmdrives were fairly new and Staples had a door crasher deal on the then huge 48MB thumbdrives yes megabytes not giga this was 2003/4?. I don't remember exactly but it was a really good deal perhaps $9 when usually back then they were $50 or something like that.
It was a good deal and an older woman was buying one too, way to go grandma! Nice to see she got one and got such a good deal, except, at the cash register of course they asked her if she wanted to purchase a protection plan for it, wtf! I glared at the clerk but didn't say anything, I can't remember if the woman went for it or not.
It's a chip surround by plastic, if it fails and your data is gone more than likely nobody can get it back anyway so a new thumbdrive is pointless. Yes I know PhotoRec but still my point is valid.
