Computer Geeks has this mem card reader/NB drive housing combo (find it in the digicam section):
"Digital photographers will love this 6-in-1 card reader/writer portable storage device. The X's Drive II features an USB 2.0 interface and data transfer rates up to 480Mbps! With support for CompactFlash cards, Smart Media, Memory Stick, Memory Stick Pro, Secure Digital, MultiMedia Cards and IBM Microdrive this device will come in handy for transferring data! The built-in LCD provides status indicators for battery life and file transfers. These won't last long so get one today."
Requires you to add a notebook drive of your own. Runs on rechargable battery.
. You can also get a 2.5 to 3.5" drive adapter there which will allow you to partition/format the notebook drive on a standard system (look in the Hard Drives section under acc'ys).
OTOH, this other one may be better for you - also from the Geeks (in the Case/PS section):
"Today's busy world means you need access to your data everywhere you go. But external drive cases for each of your devices can be a pain! Now you can take TOTAL control of the data you need anywhere - anytime! This innovative IDE converter kit provides a way for you to carry a 2.5-inch hard drive (cool), AND connect to ANY IDE device to a USB 2.0 port (very cool), AND a nifty adapter to turn a 44-pin notebook IDE interface into a standard 40-pin IDE interface (very, very cool)!! Use it at a desktop computer then take it on the road with you. Sharing data is now easier with this handy kit!"
OTTH, you could use the 2 to 3" adapter I mentioned at the end of the first paragraph to adapt your HD to any of the standard 3.5" USB/FW enclosures (in the Case/PS section) and have enough room left inside to rig your own rechargable battery pack for power. 4 to 6 Good 2000mAH NiMH AAs should do it - up to you to determine the optimum no. You shoud only need 5V (4.8 is close enough) for the interface and the NB drive - the 12V wall wart is needed to power a 3.5" drive motor so you don't need that much as NB drives use only 5V... Of course, it won't hurt to use the wall wart to provide the power if it's convenient.
