I got ahold of an old pc that has a bunch of some one elses personal stuff on it. I decided to wip the drive and got a utility called DBAN off source forge. It's suposed to scrambe the contents. I used it, but the log file said it didn't do anything, it was too short a period of time anyways I noticed. Now the BIOS doesn't see the drive. I had a similar problem when trying to do a low level format on an old Connor drive. I assumed that the company that bought Connor had the formater rigged. Some how something on the disk was changed, it's not trash, I still want to use it. Does anyone know anything about this sort of situation? It's a western digital caviar drive, 6.4GB. I've already tried manualy entering in the c/h/s. The bios acts like there is no disk hooked up.
