nice one Carol,
Pete, also look at
http://www.acercm.com/storage/storage_8824.html this comes with both usb and pcmcia cables, and is twice as fast re-writing on pcmcia, with usb available as a backup for pcs. It also has buffer under run technology, so failures are virtually banished.
Of course in the coming months usb2 will allow the highest possible speeds from suitably equipped products but then that is the story of evolving technology...
