What is the best way to wash a disk?
I tried this but it is taking forever.
dd if=/dev/zero of=/dev/sdg1
It depends who is trying to read your disk. If it's a three-letter-agency, just get a big magnet, and write it off as a loss. If not, dd using zero and a larger block size than default should do the trick. But I am sure the DoD mandates a certain number of passes of zeros/ones over the drive. I believe at a previous time it was 7 or 9 passes, using 'bcwipe.' The latter being commercial software. If you want to trash a single file, just use 'scrub' instead of 'rm' -Matt
