I have a fujitsu mpf3204at, hard disc that is mounted in an external case. I know the hard drive is fine, yet I cannot get it to read on my PC... The jumpers are correct, the cables are rightly connected, it is spinning smoothly, and by all rights should be working! I have moved the jumper around to all the settings, tried turning it off and on, just about everything! The hard drive is good and to me it does not make any sense that it would not be working. It does not even show up in the disk manager! I am running Windows 7, yet Microsoft has no reports of this being a bug, should I try closing the 1394 port? will that help? Has anyone had this problem before?
