In fact the information I need to kill to get a clean drive is all of a few hundred sectors on the hard disk. If those got wiped then you're done. Move on to booting the XP CD.
HOWEVER I'm seeing a lot of 40, 60, 80, 100, 120GB drive failures for a very simple reason. These size drives are getting old. I wouldn't be surprised...
I have a 100gb asus g1s b2a, and I am trying to go back to XP from Vista Home Edition (I think it home edition). I entered BIOS, and told it to boot up from the CD that had KillScreen on it, but I have been running it for more than 8 hours and all it says is 'active @killdisk' and some other stuff about copyright. Did it do something wrong? Should I reboot from here? Please help me!
