2nd SATA not seen; fdisk /dev/hdb can not be opened

Hi, I have an IBM Intellistation dual Opteron, with two SATA drives.
One contains both winXP and Suse 10 operating systems plus other
partitions. The second contains several partitions with data on them.

Under Windows they are seen fine, and at startup. But linux will not
see the second drive.

Searching the web, I tried to follow instrucitons which stated I should
type
fdisk /dev/hdb
but I received an error message stating something like
/dev/hdb can not be opened. I tried hdc but it's not there, and neither
is hda. However, this may be because those instructions on the web
referred to non-SATA drives and I have SATA drive (just guessing).

Any advice on how to get my second SATA drive accessible would be
appreciated.

Thanks,
Jim

The hd* devices are IDE drives. SATA drives are sd*, so your second SATA
drive would be /dev/sdb.

You can check to see what disks your kernel has found (with a 2.6
kernel), by typing

ls -ld /sys/block/[sh]d?

This depends on what kernel you have. If you have a later 2.6 kernel,
your drives will be considered scsi drives, so try /dev/sdb instead. If
you have a 2.4 kernel, it thinks of those drives as ide. If you have an
early 2.6 kernel, you probably couldn't access either sata drive, so that
is probably not the case.
