It took around 6 hours, just to write 0's to the drives with 1 pass.
If I was to do even a medium DoD wipe for example with 3 passes, it would have took in the region of 18 hours for the 1TB drives haha.
Start time: 00:28:33
End time: 06:05:24
What I do not understand however, is that if a drive has been written over 100% with 0's or 1's, why should someone do 3 or 7 passes, if data should thoroughly be wiped the first go?
Surely placing even 0's on the drive is essentially removing all data from ever being found? I don't understand that.
Drives are going back tomorrow morning
(couldn't do it today)
