check out blkid or /dev/disk/by-id/ or /dev/disk/by-uuid , you'll be able
to find the IDs of what ever drives you have plugged in and add an entry
in /etc/fstab for them like so:
# blkid
/dev/sde1: UUID="84f7fcdb-1172-42aa-bf7e-8ba09d4c8efe" SEC_TYPE="ext2" 
TYPE="ext3"

then to add it to /etc/fstab :
UUID="84f7fcdb-1172-42aa-bf7e-8ba09d4c8efe" /my/mount/point ext3  \
rw,user,noauto 0 0

I use this method for a couple usb disks that I have and it works out
pretty well.
