Apologies for the double post...

I just tried the following here, on an ext2 formatted USB stick, and it
appears to be a more flexible solution.

Say the disk is mounted as /media/disk : do this ...

sudo chown root:floppy /media/disk
sudo chmod 770 /media/disk

Now any user in the "floppy" group can read and write to the device. Any
user not in "floppy" has no access - but Ubuntu places the default user in
group floppy anyway. You could use another group instead, for example
"cdrom" - same effect. This persists across eject/umount/remount.
