Was it working before? . . How do you have it connected. I find I have the best luck if I connect the older IDE drive to the secondary channel . . temporarily disconnect the Optical drives and use that ribbon.

If it is still not recognized, in Disk Management, Right click on the drive . . select Properties . . click on the Tools tab and then Error checking . . put a check in both boxes and let it run chkdsk . . it might take a while
