I seem to have lost the power cord for my Maxtor Onetouch II 300GB hard-drive. It is one of those two piece units that has the ubiquitous power-pack attached to one piece of cord that plugs into the wall, and another piece of cord that on one end has a two-hole plastic connector that plugs into the power pack, and on the other end it has the round piece that connects to the back of the hard-drive.
The back of my drive says: 12V 3A
Any thoughts on where to acquire a new one?

Thank you,
