The first time I manually mounted, I followed Mike's
suggestion and ran "mount /dev/sdb1 /mnt" which worked
great.

I suspended and when I woke the laptop back up, the
disk had unmounted itself and wasn't remounted
automatically. I tried running "mount /dev/sdb1 /mnt"
again and I got an error message which I didn't think
to save because after about 30 seconds, the disk
automounted without me having to do it manually.

I suspended again, woke up, it was unmounted again and
ran "mount /dev/sdb1 /mnt". This time I got "mount:
special device /dev/sdb1 does not exist". So I ran
"fdisk -l":

emg at trotsky:~$ fdisk -l

Disk /dev/sdc: 320.0 GB, 320072933376 bytes
255 heads, 63 sectors/track, 38913 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Disk identifier: 0x0005d416

   Device Boot      Start         End      Blocks   Id

 Linux
emg at trotsky:~$ sudo mount -t auto /dev/sdc /mnt
mount: you must specify the filesystem type
emg at trotsky:~$ sudo mount -ext2 /dev/sdc /mnt
mount: you must specify the filesystem type

Then the help page for mount popped up which
unhelpfully didn't note how I'm supposed to format my
filesystem type argument. That's where I'm stuck now,
foiled, as usual, by a single dash.

Duh. As I was writing this, I ran:

emg at trotsky:~$ sudo mount /dev/sdc1 /mnt
emg at trotsky:~$ mount
/dev/sda2 on / type ext3 (rw,errors=remount-ro)
blahblahblah
/dev/sdc1 on /mnt type ext2 (rw)

So now it should be mounted, correct? But that's not
reflected in X. There's nothing graphical to indicate
that it's mounted and I can't save a file (in X, I
don't know how to do it via the command line) to the
drive or anything. Can I rename it manually so it
stops renaming itself every time I suspend?
