See what the kernel IDE driver thinks:
dmesg | grep ^hda
(or whatever disk it is)

You can change the C/H/S values in fdisk? This doesn't seem like such a
good idea, as they probably won't be interpreted correctly somewhere in
the BIOS or ATA bus.

Probably because changing those values inside fdisk doesn't actually
change it on the disk.
I had a very similar problem with two identical Maxtor drives a while
ago. The problem was that the BIOS was autodetecting one with LBA, and
the second without LBA. (Not that the drives had/lacked support for
LBA, as this is a BIOS feature and is not seen by the drive, but the
BIOS chose to use it for only one drive and not the other.) I had to
disable BIOS autodetection of the drives and set it manually, and it's
worked fine since.
