This is how I mount my USB drive for the BackupPC software I 
use.

In fstab I created a line so the disk would get remounted if 
the machine was restarted.

############################
LABEL=/backupdisk /data/bilbo/backup ext3 defaults 0 0
############################

My diskinit script is as follows minus some backuppc specifics:


###############################
#!/bin/bash
# USB backup disk initialization file

mount /data/bilbo/backup

if [ ! -d /data/bilbo/backup/BackupPC ];then
mkdir /data/bilbo/backup/BackupPC

chown -R backuppc.backuppc BackupPC
cd /

else

echo "BackupPC exists"

fi

# end of script
################################


To unmount the disk I have this script when switching disks:

##############################
#!/bin/bash

umount /data/bilbo/backup
##############################

This has worked flawlessly for 6 years now. I check my 
backups regularly and restore some of the critical files to 
disk just to check they are valid.

Hope this helps
