Slave HD formatting problem

Hi, yet another large hard drive issue here. I have a 160gb HDD
Seagate set as slave that will not format completely in windows.
Windows says it cannot format the drive. Here is what I have tried so
far -

- HDD jumpers are set to slave according to Seagate instructions
- HDD information is correct in BIOS (I have a Gigabyte GA-8IRX mobo)
- LBA is turned on in BIOS
- I have installed XP SP1
- Seagate's SeaTools don't seem to work, I tried using this to format
the drive but it only took a couple of seconds (!)
- I used XP's disk management to format the drive, but it failed
saying that the drive could not be formatted.
- However when I created a 50gb partition, the format WAS successful,
so I don't think there's a problem with the actual drive (windows did
not format the remaining space on the drive though)

Does anyone have any advice as to how to get this to work? I've been
reading everything I can for the past few days and I still can't work
it out.
