I agree, but ccleaner is malware/spyware and bleachbit only uses a single pass when overwriting files, it’s lead developer tries to justify this with stupid reasoning imo.
I’d recommend eraser or dban instead
It's very hard to completely wipe information on SSD's, conventional HDD's are much easier
As we all know, all phones contain ssd's (depens on model)

She was also ignorant enough to use the same phone for both accounts, it's like creating bread crumbs for the police to follow...
When will people learn to scrub drives before getting rid of them?
DBAN will scrub the drive. [Eraser] is good and (https://eraser.heidi.ie/) will scrub individual files, partitions or entire disks. If you don't want to scrub drives one by one, they sell hardware that will scrub multiple at the same time.
For failproof file deletion: Physical damage. You just can't beat a hammer.
I use Eraser. You can select the files you want to erase, clean the free space and completely wipe a drive. You can also provide a list of files to write to the space occupied with the files you want to erase to provide plausible deniability.
Edit: if you don't want to install it, there is a portable version, but I have never used it.
No. There have been reports of governments being able to recover data from single-pass wipes, like the one you described. I HIGHLY recommend downloading Eraser ( https://eraser.heidi.ie/ ) Which uses passes that originate from government organizations, all the way to paranoid computer enthusiasts, and it makes it really easy, too. It's what I use and I can't trust a command prompt to do it as easily. Ontop of that, it can wipe data off of your harddrive that you may have deleted in the past.
Seriously, I recommend it. It's entirely free, too.
Te recomiendo este programa
https://eraser.heidi.ie/download/
después de usarlo, la formateas y todo joya, todos los datos borrados son imposibles de recuperar.
Si la formateas sin usar el programa que te pasé, los datos que borraste pueden ser recuperados por eso la importancia de usar el programa
You can use https://eraser.heidi.ie/ to wipe that drive space clean after you delete files - it's a legit tool, I've used it for years.
But also a point of information - although this is true:
>Windows 10 does not actually delete it completely, rather, it marks the space that it was occupying as free space that the system is allowed to write over in the future.
it's really only a risk on spinning drives, since the majority of the data is still intact and (if it's not overwritten) it can be easily recovered.
This is not true of SSDs - they operate a bit differently. While the space is still re-allocated as free, SSD Trim will more actively "delete" those files, and they're much more difficult to recover than on a mechanical drive.
Windows:
Get safe, open-source, non-web desktop wallets for each of the coins you own in Jaxx.
Makes sure you have sent out every coin from Jaxx to these wallets so that Jaxx will be fully empty. Set view to display ALL coins. Check the destination wallets that the coins have all arrived. If this step is complete, your funds are already safe because they are not in this unsafe piece of software and no need to worry. The rest is extra safety steps and privacy clean-up.
Back up your mnemonic phrase to a secure place (e.g. use KeePass), and preferably also the private keys which held coins. Just in case.
Erase AppData storages of Jaxx with something like Eraser (https://eraser.heidi.ie/). Don't just delete because this can leave traces of your keys on your hard drive. Of course, if you still use the other wallets on this same hard drive, erasing makes no sense and you are okay with only deleting. I think Jaxx has a directory only in C:\Users<user>\AppData\Roaming, but also check out Local.
Delete the application directory (wherever you unzipped Jaxx when you started to use it).
If you're trying to make it so that your old files aren't recoverable, than I recommend encrypting your entire disk (with a randomly generated password) and then reinstalling Windows over it. If you have an SSD, simply wiping your files with a single pass isn't enough to securely remove your files. However, if you have a traditional spinning platter hard drive, running a simple eraser program on a single pass will be sufficient enough to make your files unrecoverable.
Két lehetőséged van:
ha nem tároltál rajta személyesebb adatot, akkor megpróbálhatod megkeresni az illetőt, és szólsz neki, hogy mi történt. Aztán visszaadod neki a laptopot.
Vagy pedig kitörlöd a vinyót teljes törléssel pl. 1-menetes véletlenszerű felülírásos adat móddal vagy 3-menetes DoD móddal, és többé nem foglalkozol a témával.

In terms of protection and performance impact, the Internet Security suites from Kaspersky and ESET are probably the best the moment. Both have a simple front interface, though there are plenty of settings you can change to customise it as you need.
If a built in file shredder is an absolute must then bump up to Kaspersky Total Security, but you can save your money and use good free software like Eraser - https://eraser.heidi.ie/
> overwrite the the disk sectors holding the file several times with 00 and FF
This refers to a common way to securely erase sectors on a HDD (spinning magnetic storage) where files are stored on the disk in sectors which are sections of the disk marked out and labelled when the disc is formatted.
Imagine you had a row of dominoes, some standing some flat, in a pattern that represented your data. You could lay them all flat (write 0's) but the ones that were standing might lie flat at a slightly different angle from the one that were already flat. If you make them all stand up (write FF-base16 = 11111111-base2) then the ones that were flat before might give themselves away by standing just slightly differently. If you repeatedly flatten (0) then stand (1) then randomly position (0 or 1) the dominoes then any clues about the original position of the dominoes will get lost.
More examples here : https://eraser.heidi.ie/appendix-a-erasure-methods/
SSDs work differently and this method of erasing them can cause excessive wear and tear. https://www.makeuseof.com/tag/securely-erase-ssd-without-destroying/

Once you are done with the csv on your hdd, you shouldn't just delete it as it can be recovered.
Once you have imported the csv into Keepass you should securely erase the csv from your hdd.
OK - I would consider work to be less of a risk than donating or giving your computer to someone.
I would uninstall LastPass and then enable two-factor authentication on your account. Then remove all of your one-time passwords and then run something like Eraser to wipe free disk space. This can take time, make sure to only select free disk space. This will prevent (or make more difficult) restoration of deleted files without removing everything on your computer. It can take some time. In theory, if LastPass was uninstalled and there was a local copy of your encrypted password file, it would be securely deleted.
Remove one-time passwords: https://support.logmeininc.com/lastpass/help/how-do-i-clear-my-temporary-one-time-passwords-for-lastpass
There are tools already mentioned in the comments above, but here are some I haven't seen yet. There is DBan, https://dban.org/ . Another is Eraser, https://eraser.heidi.ie/ . They might be a bit more extreme than you need but they are there if you want to really get rid of data or format a drive.
Edit: You should create a boot disk or usb for windows and reinstall windows. Then format the hdd after moving the files over.

You can use this to securely wipe the free space on your HDD. Once you purge all of your personal files, just run that (overnight - it takes a while) and you’ll be good.
Overwrite the files with Eraser on Windows.
https://eraser.heidi.ie/ allows you to permanently delete files with no chance of them ever being recovered in any way, though it takes a HELL of a long time for a lot of files. Also encrypt shit with VeraCrypt.
Run Eraser on your laptop: https://eraser.heidi.ie/ It securely wipes the drive by overwriting it with 1s and 0s. There are a number of different erase methods you can choose, the fastest one takes about 10 hours to erase a 200GB drive, so set it running in the morning before you go out. Hell, run the process a couple of times on the same drive if you want to be completely certain.
Depends how many times you have overwritten! Above mentioned software recovered my files after i have overwritten the same memory space thrice. Its advanced mode takes long processing time but it can recover. You can use advanced software to erase your data so that it will be nearly impossible to recover.
I'm sorry to hear it, that sucks. Do report your suspicions to the Apple store you used. If someone there shows up to work the Genius bar in a Lambo, he may be a suspect.
But yes, this really highlights the level of attention you have to pay to even things like deleting the trash securely.
On Windows, installing https://eraser.heidi.ie/ may be a good idea. It can be set to zero out empty space and really overwrite the space used by the recycle bin data.
If you didn't need to maintain Windows or software, I'd just use DBAN. Since you do need to maintain those things, File Shredder or Eraser have worked for me.
I'm no security expert, so maybe others know of better options. I can't vouch for the integrity of the above manufacturers.
That is true. It just marks the space as available. The files can still be recovered but it shouldn't actually effect the amount of space you have available.
More on security though. Once it's written over it is 'deleted' and not just marked as 'empty' by the file system. In theory, the more overwrites, the 'more deleted'. One overwrite will stop virtually any attempt to read it unless you're trying to keep the FBI/CIA out or something.
A tool like CCleaner has a delete feature where it deletes and overwrites the empty space with 1s and/or 0s. There's also a tool called Eraser that lets you do it on a per-file basis and securely 'shred' whatever the document is. You should be able to set how many overwrites it does. The more overwrites the longer the process takes, but it's more secure in theory. 7 overwrites is a commonly cited 'good' number.
They probably can technically recover the files easily. But, they're a realty office and not an IT office. I'd recover it in 10 minutes if I knew the drive directory to your personal server. They could hire an IT contractor to come take care of it but probably don't know that they can even be recovered.
At this point I'd just play dumb with them. Ignore the first letter and see if they just let it go. If they send another one then maybe respond and say that "I'm not sure which files you're referring to. Could you be more specific?" Maybe add something like, "I've had a hard drive crash and lost most of what I had on my laptop, including family photos, etc." This is just to blow smoke up their ass and make them think they're wasting their time with you. And, if push comes to shove buy an old laptop on CL for $100 and remove the hard drive. Put it in a small box without bubble wrap or any protection, and chuck the box against a brick or concrete wall super hard about 20 times. That'll destroy the hard drive. Then, you could offer the hard drive to them and say, "if you can fix it you can take what you want. But, please let me have my family photos."
Also, run a shredding program on the hard drive before you remove and erase it.
This will make them show their hand as to whether they know something or just are conducting a fishing expedition (likely the latter).
Eraser is one of the best free software products for deleting files or hard disks drives safely. It has several algorithms for safe data cleaning.
I'm not sure if I understood your question right, so I'm suggesting Eraser as a generic software for this kind of operations. However, is you need to specifically delete only restore points, in unrecoverable ways, I'm not aware of any software that specific. Usually, it only makes sense that one either deletes specific files or directories, or the whole hard drive.
Well, unless:
- you used an app to completely zero-out the entire drive.
- you used an app like Eraser (https://eraser.heidi.ie/) to overwrite dozens of times the section on the harddrive where the document(s) were.
- after deleting the data / repartitioning the drive, you filled it so full of data that it over-wrote the section where your document(s) were
Feasibly, in any of those scenarios, the data CANNOT be recovered.... or am I wrong, and somehow there's now ways of microscopically scraping molecular-nano-level imprinting of the 1s and 0s that somehow exist underneath of that section of data storage that has been over-written several dozen times?
No where. Files removed by your basic recycling bin go no where. That's why you can access the with data recovery tools. Your computer "keeps tabs" basically on all places on the drive which are currently being taken up. When you "delete" a file, what's actually deleted is that "tab" that the computer had and it now recognizes the space as unoccupied and ready for new data. When you write data to the same space, it overwrites the old data, which is the cause for corruption when recovering deleted files, some of its data is missing.
​
A little more technical: Files are never deleted. The system has a table of every reference on the disk which is taken up, called a file system table or file allocation table (originally developed for floppy disks). When you "empty recycling bin" the table removes all references to that data and essentially the drive itself forgets the data, which in terms of the drive marks the space as open for new data. Tools like Eraser remove the files and then overwrite the data with gibberish, usually many times. It does this more than once because, on a hard drive, you can still recover overwritten data by studying the magnetic fields from the platter's surface.
- Reformat the drive, replace it altogether and destroy the original or
- Use a 3rd party software like Eraser to overwrite the space on the disk.

If it's a spinning hard disk or SD/MMC (think cheap netbooks), ERASER (https://eraser.heidi.ie/ ) is the most convenient. It integrates with explorer, and even wipes cluster tips. Just remember to launch it with admin permissions or it can get tangled up. If it's an SSD/NVMe, just delete files, empty trash, and wait. Once the SSD controller has been told the clusters have been deleted by Windows via TRIM, the controller will pick an idle time and wipe the memory cells itself. Usually only takes a few minutes.
Eraser. Just do as many passes of random data as you want depending on how safely you want it to be wiped. After one wipe the data is already impossible to recover just using software and expensive data recovery is needed to restore parts of it. If you want to be very sure do a few passes more. But don't use the Gutmann algorithm. It was designed for now very old types of hard drives and wastes a lot of time for no advantage.
To secure files you need to encrypt them. Use a Veracrypt container maybe. But without a strong password the best encryption tool is useless.
You can erase it using this: https://eraser.heidi.ie/download/
​
Then set it to rewrite at least 2 times. I don't recommend doing any more than that because it sort is useless.
Use Eraser (https://eraser.heidi.ie/) to forensically wipe the 1TB drive. It will allow you to choose the drive you wish to erase and give you a variety of levels of wiping from a simple format to 35-passes of random data.
We like to use Eraser as it allows for a truly unreversible number of verified writes and erasers source code is all open source and allows for verification. As well the Eraser team has been supporting the product for a long time and is public, not hidden behind some invisible corporate mysto language.
It works for everything from Win XP up.
> My question is really around what folks processes are for erasing drives?
The title of your topic didn't exactly mention this, but here's what I do:
I have a powered SATA adapter to connect a drive to my PC, so in such a case I would connect that drive to my PC, quick-format it and then use Eraser to wipe the empty space on the drive.
Make sure that you pick the desired wipe algorithm. IIRC the default algorithm wipes empty space three times, but that might be a bit overkill. Doesn't hurt of course, but just takes three times as long.
> The drive (4TB WD RED - EFRX) is still covered under warranty
Just make sure that the replacement drive isn't going to be an SMR drive.
You got it :D. However, I'd do the long smart test first. No sense in DBAN if the drive is bad anyways. If the drive tests bad, physically destroy it to wipe it. A few .45 ACP bullets through the platters work well for that.
As for connecting the drive to another system. Formatting in disk manager isn't a secure wipe. Use Eraser or similar windows program to do a DoD Short wipe on it.
As most have recommend you can use eraser to delete your files to make sure it's unrecognizable. If you have already deleted your file, you can use eraser's function to wipe the unused disk space on your disk to make it so that recuva will also be unable to find the file name of the deleted files.
Note that option 1 is much faster than option 2, but since you've already deleted the file you don't really have a choice.
Use a utility like Eraser to wipe the hard drive. If you have banking information, legal documents, or nuclear launch codes that need to be absolutely secure, go into Eraser's settings and select either the Schneier (7 pass) or Gutmann (35 pass) setting as the default drive erasure method. If the most personal thing on your computer is your small collection of Brooklyn Nine-Nine fan fiction, use one of the 3-pass or 7-pass options.
Note: if your laptop has a solid state drive (SSD) rather than a normal hard drive with rotating magnetic platters (HDD), these methods will not be fully effective.
Eraser is a secure file deletion utility.
It identifies the physical location of the file on the disk and overwrites it with lots of random data which can make it difficult for forensic data recovery.
There's many different types of algorithms Eraser offers to properly wipe drives / files and it's mostly straightforward. Guttmann is the default but honestly that does 35 passes and takes WAY too long, and it's going to take fucking forever on a 2TB drive. I would recommend something that does 3, 5, or 7 passes, depending on just how much you really care about that data
(though, 3 should honestly be enough unless you're trying to hide your data from the government for some reason)
Most "secure erase" type programs can customize the pattern used to overwrite the deleted file space.
In particular, I'm thinking of the freeware program Eraser, which can use any custom patter the user specifies:
Eraser is THE solution.
It works as overriding your hdd over and over. It uses many standards, including the one US military uses. It renders data recovery impossible. I personally use it. You can get it here.
You can use this.
Run it from within Windows and erase using Russian Gost (2 passes) - it supports both HDD and SSD. You can erase the three remaining drives in any order.
Reinstall Windows to a blank SSD.
Then erase the disk which is currently running Windows from within your new Windows installation.
Thanks
Which option would be best? I was thinking of either running Eraser on it or just using BitLocker to encrypt the whole disk and then running a quick format afterwards. The encryption key would never be on the drive being erased and the format is just to make it so it doesn't harass the next person to decrypt it. Or would clean all be the easiest way to do it while also accomplishing the same end goal?
On a computer, no matter what type of machine you're using, your first move should be to delete the file from File Explorer in Windows or Finder in macOS. Then clear out whichever undelete tool your operating system uses, either the Recycle Bin or the Trash folder. That's where most people would stop and move on to another task, leaving their data vulnerable. Here's what you need to do next.
To overcome this problem and securely remove a file or folder, you need the help of a third-party program. For Windows, the simple Eraser tool is one of the best choices .For Mac, you can try to use iMyMac–File Shredder,you can use it to securely delete files on mac.
Once you have the computer reinstalled with a clean copy of Windows, you can use Eraser to wipe the unused space and delete any lingering ~~porn~~ files that might still be hanging around in the unused space. (You can also set it to erase the slack space inside of used clusters.) It's a really slow process, but will work.
If you have a SSD, you will need to use the drive's secure erase procedure which will wipe the recovery partition.
>try right clicking on the shortcut and selecting "Run as Administrator"
Same result. The task is completed but the files in the recycling bin aren't deleted.
​
>If you learn how to use the windows command line, you can delete files without them ever heading to the recycle bin.
Wether it's by using the Windows terminal or emptying the recycling bin, Windows won't securely erase the data either way. For an explanation why, read Eraser's home page and what it says under "Why use eraser?".
Forensic recovery tools can retrieve data from a HDD even after formatting. To obliterate your data completely:
HDD's - DBAN
SSD's - Maybe, maybe not. There's a 25% to 96% chance of success.
Basically google any free drive wiping program and you should be good to go. Even the one is CCleaner is enough. I use Eraser also don't worry about the number of passes, one is usually enough.
Do you have anything else you need in the videos folder?
I'm thinking about creating a new user account as a temporary measure, sign into it then go to C:\Users\(your user profile name) and right click videos and remove it or erase it through a file shredder like https://eraser.heidi.ie/
Then create another Video folder, switch back to your original user profile and remove the temporary user profile you created.
If you want to keep Windows on there, try this guy out:
Just delete all the files you don't want people to have, then tell Eraser to securely delete free space. Alternatively tell Eraser to securely delete the files you don't want people to be able to access.
Honestly, just deleting your files should be enough. I highly doubt someone you sell your laptop to will go to the trouble of doing data recovery on it.
What you are looking for is Eraser: https://eraser.heidi.ie/.
It can delete specific files, and clear unused space as well. It can also overwrite the files if you want to go that route. I recommend you permanently delete everything in windows, then clear your cache and site history from the browser, then have eraser overwrite all unused space. This leaves the OS intact, and makes any files that you deleted/cleared unrecoverable.
This is a solid response. Is Eraser more thorough in your opinion? Can it overwrite all unallocated space? If not, what is the best?
Also just curious, is there a way for a consumer to obtain Magnet's software (IEF Or Axiom)? Is it any better than the other forensics software out there? The article depicts it like it can do things other forensics software can't.
Depends, do you want to do a clean installation of the operating system or are you trying to save those files on the old hard drive?
I would set up the OS on the new HD and transfer old files to a designated partition you would like to use for storage, install Eraser (https://eraser.heidi.ie/), do a multipass wipe on the old HDD and then melt that MF into scrap metal.
Then it's perfect! I don't think that's too paranoid of you at all. I would actually recommend using something like Eraser to securely erase a disk, in that case.
Eraser overwrites your deleted data with a random pattern of meaningless bits. This makes it impossible to recover data from the disk. A standard format just erases the file table and marks the data as overwrite-eligible, so it's trivial to recover information with a tool like DiskDrill or Disk Warrior.
You apparently have to do it by exporting your passwords to a csv file. KeePass documentation and step-by-step guide. Make sure you run a Malwarebytes scan before exporting, and a disk scrub afterwards!
I'm using eraser because I want to make a full erase of few folders(personal stuff that i don't care anymore), Eraser is a software that allows you to delete files/folders/drives with erasing methods, I'm currently using one that write 0s where the file were..
I'm trying to know if it could be dangerous on a SSD :)

> I have nothing to hide in terms of databases and other sensitive info they may be concerned about, but have had email correspondence (on my personal gmail account) with new business partners which I do not wish to be seen by my present organisation.
> My question is if I delete gmail from the laptop, as well as any other personal info I wish to keep private, will a forensic search of the laptop retrieve this?
Yes, unless you use ccleaner and then wipe the unallocated space (use https://eraser.heidi.ie/ for this). You must have administrative privileges to your drive.
I am not familiar with the details of clinton's case but since this is just about a buyer wanting to remove the evidence of a handful of purchases he will be perfectly fine if he uses a tool like eraser [https://eraser.heidi.ie/] and chooses an erase method with at least 3 passes. in doubt he can always physically destroy the hard drive.
Using an SSD with TRIM enabled will erase the data of deleted files all by itself. But there's also eraser: https://eraser.heidi.ie/
If you use Linux, you can just read from /dev/zero or /dev/urandom, and pipe it to a file.
Deleting doesn't really erase the bytes from the drive. It just goes to the entry in the file list and says "this is deleted." The space doesn't really need to be erased, it can just be reused as is.
Now, if you need to remove something down to that level, you use a specific tool that will do that (like Eraser), and it does take about as long as it does to copy or move the same file (in the simplest mode), because it really will be writing that entire file length to disk, although just zeroes or random data.
I don't know how effective a Windows 10 reset is, but I suspect your "deleted" files will be recoverable without too much effort.
I would suggest that, after you have reset Windows 10, you run Eraser and use it to securely wife all the free space on the drive.
