Does the drive even show up under, "My Computer", as a drive?
YES
I will assume the hard drive is correctly attached to the motherboard and power supply, using either an serial ATA cable or a proper ribbon cable. I need to know more specifics about how yours is connected to the motherboard, whether as a slave to the master drive, or what?
The drive I want to erase is a second internal drive that I put in, iIfollowed the directions to the T that was in the seagate manual.
When the computer is powered up, does the drive feel or sound like it is spinning. If not, you have a problem.
YES
Another consideration is whether you have even configured the jumpers on the hard drive itself to be recognized as a slave drive and how you have the drive connected to the motherboard?
Yes the jumpers are set.
How big is your hard drive?
120gigs, but in the poperties its says its 111 gigs
This is very important before getting started with helping you. First of all, the OS you are using may affect the way you want to format the drive (DOS or NTFS file system). Second, Windows XP may not fully recognize the total capacity of some larger hard drives, so that is a consideration. If that is the case, you won't be able to proceed, and a small downloadable file may be needed.
I am running XP home, and the the drive is NTFS file type.
