fc5 problem (can't mount spare hd)

I've installed FC5 on several machines since last week, and my desktop
at home is the biggest problem I've had so far.

I have a 200GB drive that mounts just fine in OpenSUSE 10 and fc4, but
in fc5 I get:

[blr at scooby ~]$ sudo mount /mnt/video/
mount: /dev/hdc1 is not a valid block device

from /etc/fstab:
/dev/hdc1               /mnt/video             ext3    defaults        0 0

from dmesg:

[blr at scooby ~]$ sudo /sbin/fdisk -l /dev/hdc

For I while I was getting errors from smartd:
Apr  2 04:28:00 scooby smartd[4864]: Device: /dev/hdc, 1 Currently unreadable (pending) sectors
Apr  2 04:28:00 scooby smartd[4864]: Device: /dev/hdc, 2 Offline uncorrectable sectors

But I went through the "Bad Sector HOWTO", and I'm not getting errors
any more, and smartctl says:

I've powered down and re-booted with smartd disabled, and I still
can't get the thing to mount.  Any ideas?

Oh yeah, the vanilla FC5 kernel (2.6.15-1.2054_FC5), the corresponding
Xen0 kernel, and the openVZ kernel (2.6.16-026test005.1) all do the
same thing.  I'm stumped.
