That's a very good question. You can't see the power draw of a USB device until you hook it up. Things depend not only on the maximum current for that one USB port, but also the total current the PC can supply over all the USB ports.

PG Music supplies drives made by Toshiba and Hitachi, according to a post by Peter Gannon.

Of course, if you are willing, you can use a drive that has its own power supply. The audiophile drive I just received from PG Music has a 12 volt external power wall wart.
