Windows 10 Reset, HD clean?


Recommended Posts

If I do a Windows 10 reset, erasing everything, is it safe to sell my PC?

Do I need to use other software to wipe my HD.

Or is the Windows reset format sufficient to remove all files and thus keep my information (multi million dollar off shore accounts, mistresses etc.) safe.

 

thanks

Remove the HDD and replace it with another....or an SSD.

reset only deletes and reinstall windows, if you are worried about any data they could recover (and they technically could) then you would have to use something else to wipe it.

There is a program named 'bcwipe' by Jetico - this will solve your problem.

 

Only a single overwrite is required and that can be done in the free version.

 

What it does is fill up the entire hard drive overwriting everything that may have been there before.

 

There are other things it can do like cleaning the empty space (remnants if you will) at the end of each file and directory but allocated to the file, these parts would be missed by something that merely fills up the drive.

Thanks for the suggestions, I'll download bcwipe.

 

But are you sure its necessary, I heard that when you delete everything and reinstall, it does get rid of everything if you chose to remove everything.

Does it matter, running this will take a few hours then it's done. If you want to be sure then you're going to need to image your hard drive and scan it to see what kind of files can be recovered - exactly what the people who go looking for data do.

Its just more work, and to reinstall Win10 is more work, that's all.

But if its necessary, then it must be done!

 

How do you image a hard drive and scan it?

 

Thanks

It is NEVER 100% safe to pass on a hard drive (HDD or SSD) that has ever had personal information on it. These wiping programs still do not remove all traces of everything. @Bruno123 had the right answer.

 

Or just simply sell the PC without a hard drive

Or, buy the cheapest hard drive you can, bung Windows on it as a new installation and keep your old drive.

 

I bought 2 second user PCs recently from Amazon's "Renewed Store". Despite them arriving "ready to run" I still trashed the hard drives and rebuilt Windows on them - with SSDs it takes about an hour but my particular setup requirements take about a day per PC (obviously I did them "in parallel" to save time.

You can use

 

https://privazer.com/en/

 

to securely erase the private data then erase the free space. You can then do a Win 10 reset if it makes you feel better and wipe free space again. Note that it will handle SSDs. Paranoia notwithstanding, this will be more than sufficient. (A similar program is BleachBit, which worked well for Hillary Clinton.)

 

Re: SSDs, if you want to go thru a new install, you can use your SSD vendor's software to enable a secure erase. https://www.wepc.com/how-to/securely-erase-an-ssd-drive/.

Some interesting "Cleaning" tools mentioned, but looking closely some of them only wipe files that you want to delete, not wipe a whole disk :sad:

 

https://www.killdisk.com/eraser.html  -  Will destroy all data on a disk including any partitions or left over fragments of partitions and overwrite with military grade code, making it virtually impossible for any possibility to recover any data.

 

It's what I use :thumbsup:

But as you say...virtually impossible....not totally impossible. Having worked with military IT I can tell you that given enough time and effort, some data could still be recovered - especially off an older HDD....not so much from newer SSDs.

 

Of corser the likelihood of your old drive falling into those sort of hands is minimal.

Of course given enough time and resources it would probably be possible to recover data, but as you say who would bother with the data from a personal computer.

 

To be 100% sure of deleting data from a drive it would have to be totally destroyed and ground into dust.

 

For the average person to clean a drive the "[email protected] KillDisk" program is about as good as one can get.

Probably - when I remove a drive from one of my computers, it either gets reused in another of MY computers, or, as you imply physically destroyed - platters ripped out and broken into several pieces, then scattered.

 

Bit like my home WiFi - the only machines that can connect to it are those whose MAC addresses are registered and have the multi, multi-character passcode (not even saying how many!)

I'm not paranoid....but the buggers ARE out to get us!! 🤪
