Completely Wiping, Recovering?

post #1 of 7
Thread Starter 
I am planning to sell my computer, and with that I want to sell my hard drive. Although I am concerned whether the person would be able to recovery anything. How can you completely remove everything that was on the drive, and make it impossible to ever retrieve any info from before it was wiped??

ERD Commander. might be hard to find but it's what's used to wipe classified drives in the military.

I use Killdisk it writes zeros (0) to partitions or the entire drive. If i'm wiping the drive for me i use a single pass but if i'm selling to someone else i use two passes.

Forgot to put up a link:http://www.killdisk.com/

yep KillDisk is the way to go
I have sold around 5 comps to complete stranges and used KillDisk every single time

Lets say you wanted to hide something from the LAPD. KillDisk is that good

anything that conforms to the DoD 5220.22-M standard should be good (not saying you need to follow military steps to erase data, but it's good if you really want to erase something)

Conforming to a "standard" that doesn't actually specify any particular data erasure methods? LOL.

If you're just selling the drive, it's sufficient to wipe the disk once with any utility you like.

doesn't specify any methods? even the KillDisk website explains the procedure:

d. Overwrite all addressable locations with a character, its complement, then a random character and verify. THIS METHOD IS NOT APPROVED FOR SANITIZING MEDIA THAT CONTAINS TOP SECRET INFORMATION.
To OP: You should check out this thread: How do you know if something is truly deleted without reformatting?
