Ok, to hijack the thread a bit, I now am looking for a 2.5 inch drive enclosure. It will be used on both my Powerbook and my new Dell brick portable (Inspiron 9100). After having my USB port on the Powerbook fail once and Bruno with his horror story, I want 6 pin bus powered firewire for it. However, the brick lacks a 6 pin firewire port, though it does have a 4 pin one. It also has 5 USB 2 ports, but no PS/2 legacy port. So...

Anyone know of a 2.5 inch drive enclosure that is firewire and USB bus powered? The ones I looked through are either firewire only, or USB only with a PS/2 power port for use with the Firewire port. The goal is to just thow one cable in each respective laptop bag, and just use the drive on either when needed.
