I bought a 4gb Monstor Drive from Radio Shack today, and I got this thing home and I cant get it to work. I am not sure if I am doing something wrong, if it doesn't support macs, or if its a piece of garbage. I have a Powerbook G4 1 gig, OS X Tiger. I tried plugging it into the computer straight and tried using the cord it came with. Neither seem to bring it up... It came with a mini disc but I am sure my powerbook can read those?
