There is a problem. I would disconnect all IDE devices an leave only 120GB
as Primary Master.
BIOS setting should be:
- Type of fixed disk - Auto
- Access mode - Auto or LBA

Disconnect other disks/CD, check IDE cable, HD jumpers.
Do not overclock anything.

Do you care about files on your hard drives?
If you do, disconnect them all and work with your 15GB drive alone to locate
where problem is.
