I've got a 1TB USB Maxtor hard drive and wasn't sure how to zero fill it?
It got corrupted so wanted to give it a clean wipe.
I tried SeaTools for Windos but that did not work.
I have Windows XP 64bit.
grab a linux live iso like knoppix. boot it.
run shred on drive ( fills drive with random info).
you can kill shred after 1 pass ( default is 25)
