I want to clean up all my hard drives, so I may sell them...I was thinking of using some commercial grade delete tool but because money is an issue, can someone help me do this with the old dos debug command? I didn't think there was a way to clear hard drives that way, but google came up with that as a choice...I would like to try this via a batch file but I don't know if this is possible, (to make it automated) is it? I found a couple of sites that explain how to do this using one drive at a time, but how can this be done in one file for many drives? I have 32 hard drives to wipe, and they all have junk on them...Everything from spyware, to viruii.

My thoughts were to plug 6 drives in at a time, since that's how many ports I have available at once, and use an automatic way of wiping them all out at once (unattended mode)..This does have to be done in the quickest way possible, and I don't think one at a time is going to cut it.

Thanks again.

why don't just re-partition them with quick format? it is fast
