One of the first things to go in an older drive can often be the spindle-motor/bearings. If it doesn't spin up, those could be toast. The other possibility is that the power molex connector in the back is loose/disconnected, or there is a frayed wire somewhere. If you are using power-molex Y splitters, then that could easily be the cause. (On some drives, the electronics will still be powered solely by the IDE cable, enough to report the "identify drive" command back to the host system. Continued operation like that will likely burn out the mobo's IDE ports, though.)
Considering that you can get a replacement 52x32x52 CD-RW drive for $20, or a combo that includes a DVD-ROM 16x reader for $30, or a 16X DVD burner for $60, it's probably due for a replacement anyways. So perhaps this was the drive's way of hinting at an upgrade?
