Hello, Rowan.

The hex number is the UUID of the filesystem, which is used to locate it 
instead of using an actual device name that can change when you plug in 
external drives or fiddle with the hard disk order in the BIOS. Try:

   ls -l /dev/disk/by-uuid/

If you use UUID's in your /etc/fstab instead of device names, then 
filesystems can be found despite changes to device names. These links 
are created automatically when you build a new filesystem. You can check 
what the UUID of a filsystem is (e.g. on /dev/sda1) using:

   sudo blkid /dev/sda1

Now you're running 10.04, you can use the disk utility to check the 
health of your disks,

   System/Administration/Disk Utility

Have a look at the SMART data for your internal disk.

Bye,

   Tony.
