Hdd Card Reader Does Anyone Know Why I Am Getting I/O Device Error Message While Trying To Hook Up The External HDD(USB)?

Does anyone know why I am getting I/O device Error message while trying to hook up the external HDD(USB)? - hdd card reader

I bought this card reader, external hard drive for storing e-bay. It Digimat II-Plus and Hitachi Travelstar 60GB 2.5 "HDD.

I managed to format the hard drive by, it is formatted in FAT32 in two discs, and looks like a backup of files quickly, but could not be detected on the computer or recognizing (sometimes) no transfer of copied files on drive C: \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\ \\, shows only I / O device error.

It was a forum about this issue, but the guys seem to have answers to all the experts (http://photography-on-the.net/forum/showthread.php?t=84059&page=2). I need a quick solution. If you know the answer, call me soon. Thank you!
