I have an Acomdata external drive (300GB) but device manager under Systems shown it as unknown device, how can I get this external drive to work? (Note: blue light is on indicating device is good.) I am running under XP Prof. on a Dell Optima GX280.

Try it on another computer. If it doesn't work then it's probably defective. Unfortunate but it happens.

If you can remove the hard drive from the Acomdata shell then it's possible the drive itself is okay and just the Acomdata electronics is defective.

The HD in the unit is good, i.e., it has already been checked out (blue light also gives evidence that HD is okay). Is therea driver needed?

The blue light doesn't mean anything other than it has power and perhaps is connected to the computer.

Please try it on another computer to verify it's good. It's the simplest way to check it out and save you a lot of aggravation if it is defective.

Do you connect via USB or Firewire? Have you tried moving it to other ports? FOr instance, if you normally plug it in the front of the computer, try one of the rear ports. If you are using a port replicator, is it powered or passive (does it have an external power supply)? Have you tried not using it, just connect directly to the computer port?
