Its getting the cylinders, sectors and heads wrong, probably at any rate. Check "dmesg" and see the report of the drive's geometry, it'll look like this:
Code:
hdb: 120060864 sectors (61471 MB) w/2048KiB Cache, CHS=7473/255/63, UDMA(66)
See if that actually matches your drive's specs, CHS is cylinders, heads, sectors...
Its probably just a legacy BIOS bug, as in your bios is having a stupid attack over the drive. What's the age of the mobo offhand?
