I bought a 2.5 laptop internal drive, and an enclosure for it. The enclosure only has USB 2.0. I had a guy at work format it in Fat32 so I could use it with my iBook and my PC. Well when is is said and done the external HD is seen by my PC but not by the iBook. I bought this thing for the iBook. Can anyone tell me what I am doing wrong. The drive is spinning when I connect the external to the ibook, but I don't see a drive show up on my desktop. The enclosure has two USB 2.0 plugs that I plug in at the same time. Help please.
