Wiping External Drive from Windows

zazon 1,494 April 8, 2016 at 12:00 AM
It's been a long time since I've wiped a drive, but I got one of those 4TB external drives and need to sell my 2TB, so it needs to be wiped good. I tried Heidi Eraser, but it kept shutting itself down in Windows 7, so is there some way to fix that or a better option? I'd prefer not leave the PC in DOS mode while wiping it if possible. Thanks for any help.

There are so many, I usually use bootable programs like easeus or dban but there are many different programs you can try.

DBAN (www.dban.org) is the best tool for disk wipes.

DBAN is great, but it's a boot disk and the OP needs to be super careful to select the correct drive. I would go as far as to unplug the drives I don't want erased before proceeding.

OP, I would ask how much your actually going to get for a 2TB used drive and if it would be better to keep it and have an offline backup copy of some of your data. Personally I would have a very hard time buying a used hard drive. You never know what conditions it was used in, how many hours it had etc.

I agree not a strong market for used hard drives. I'd just keep it, even disconnected as a long term backup.

If you still want to wipe it, Eraser, which didn't work for you is the main thing that comes to mind that works within windows. DBAN gets my vote, unplug other drives first to prevent accidents, just start it and go to bed.

or this shit, www hdtune com, not a good one, can't choose where to start, so it can't be interrupted.
i think one zero fill should be sufficient for HDD.

or just create an empty file and copy to it, this way doesn't erase the file table at the beginning of the partition, but the tool you were using should already erased it

East tec eraser is what we tend to use at work, there is a free trial version just be aware it will take a long time I would do 2 passes and reformat drive full format not quick, do it twice with different cluster size.

Then try recuva
https://www.piriform.com/recuva
or r-studio which you can try for free

if they can't recover you files you are fine

And your data is based on what?

Mine is based on actual experience and data like this:

http://www.makeuseof.com/tag/diff...explained/


Most experts say that choosing the full format feature (preferably NTFS over FAT) is better suited for your computer. For a handful of reasons, this is correct. A full format completely wipes your hard drive. After a full format, there shouldn't be any recoverable data left that a program could sniff out

https://datarecovery.wondershare....drive.html

If you performed a quick format your data can be recovered easily but in the case of full format every sector is overwritten.

The big test is to just see if you can recover the data, a 3X wipe can take more than a day and really does stress the drive.
