You can't have both. Unplugging hot stuff from non-swap hardware is even nastier. If you need removable media, get a dvd-+rw. Do not get used drives on e-bay. They can't be trusted. Another option is to make a fileserver out of an old obsolete box. Also, an advice: DO NOT GET CHEAP ON BACKUP. YOU WILL REGRET IT.
