Looks to me, as if the kernel sees it... have you tried a manual mount? What sort of
disk, is it (i.e., 3.5" notebook, etc)?

Cheers

Palimpsest uses SMART to report on disk vitality which is unfortunately
unsupported with USB-attached hard disks from what I've seen. If you
can remove the drive from its enclosure and attach it directly to the
ATA/SATA/SCSI interface, you may have better luck. Some manufacturers
such as Seagate have utilities for testing of their external drives.

I've used this on ATA drives and perhaps a newer version works with you.

You might want to do "badblocks /dev/sdb" without mounting the harddisk.
