System->Computer no longer shows camera and unmounted drives

[slick_rick]

When I plug my camera in it used to appear in System->Computer, but not anymore. I can still import photos via the F-Spot photo import thingy, but sometimes I really just want to manage the flash like a disk via a GUI.

Possibly related: /dev/sdc is a drive with two partitions (a swap and a big ext3). I'm positive of this as is fdisk:

richard@mewtwo:~$ sudo fdisk /dev/sdc
<snip>
Command (m for help): p

Disk /dev/sdc: 200.0 GB, 200049647616 bytes
255 heads, 63 sectors/track, 24321 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: <snip>

Device Boot Start End Blocks Id System
/dev/sdc1 1 32 257008+ 82 Linux swap / Solaris
/dev/sdc2 33 24321 195101392+ 83 Linux

However for some reason the partitions aren'tt showing up in /dev:
richard@mewtwo:~$ ls -ltr /dev/sd*
brw-rw---- 1 root disk 8, 18 2008-07-19 15:25 /dev/sdb2
brw-rw---- 1 root disk 8, 32 2008-07-19 15:26 /dev/sdc
brw-rw---- 1 root disk 8, 16 2008-07-19 15:26 /dev/sdb
brw-rw---- 1 root disk 8, 0 2008-07-19 15:26 /dev/sda
brw-rw---- 1 root disk 8, 2 2008-07-19 15:26 /dev/sda2
brw-rw---- 1 root disk 8, 17 2008-07-19 15:26 /dev/sdb1
brw-rw---- 1 root disk 8, 5 2008-07-19 15:26 /dev/sda5
brw-rw---- 1 root disk 8, 1 2008-07-19 15:27 /dev/sda1

I used to be able to mount /dev/sdc2 from.... You guessed it, system->computer, but now I can't mount it at all:
richard@mewtwo:~$ sudo mount /dev/sdc2 /mnt
mount: special device /dev/sdc2 does not exist

TIA!
