you need to zero fill the drive .............. end of story


focus on that task .......................

try Killdisk ................

or use the hard drive manufacturers free utilities ............. in the hard drive diagnostic package they have a zero fill utility ................

see if you can get that version to zero fill your drive ..............

Dban is the only wiper I personally would bet my "freedom" on as far as cleaning a drive .............. so once you get it wiped with killdisk or other single pass wiper ............ then run Dariks Boot n Nuke (dban)
