Best way to permanently remove data from a hard drive?

post #1 of 22
Thread Starter 
I know you can recover files with some tools like recuva or other more advanced software, i want to destroy some very important files i have on my HD and make them completely "disappear" forever

Is there any reliable software or the only way is getting rid of the HD?


Thank you for helping me out.

Are you looking to erase the entire hard drive, or just a few portions?

Killdisk will reset the entire hard drive.

I prefer the grenade or a stick of dynamite.
The more subtle approach would be some free software to do several secure wipe passes.

Ccleaner has a wipe free space utility so you can remove data you deleted permanently as well as a drive wiper. Eraser is another free secure wipe program. There are plenty of free programs out there for that.

get a copy of acronis true image it has a utillity that rewrites the hard drive to 1s and 0s and destroys any usable data on the hard drive it prevents even the best data recovery programs from finding it.

if you are going to throw the hard drives out just run a magnet over them that will prevent the drive from ever working again

There is software you can buy, but if you read up a little on Linux, you could do it for free -

Wiki on how to clean a hard drive

Hard drives are pretty cheap these days. Take it out, take it apart, break the disks, and throw the pieces away in different places.

Wipe it with one of the above tools, then fill it with as many huge files as will fit, then format once more. Any recovery efforts will then only get the junk files you filled it with. Windows (or big Linux) ISO images at 4.6GB each are useful for that.
