I will definitely try to play with termination and jumpers, I did not think about changing them, but the power supply was tested to be fine, so luckily no problems there. The problem is, nothing happens when the drive gets powered on. The spindle spins for only a moment, and nothing else happens. The read/write led does not illuminate, the laser does not try to seek, it just sits there. I suspect something on the board itself has just died, but I would much rather troubleshoot further than to completely replace the drive.

Is there any control on the board or is it just a power supply board? I have been unable to find any picture detailing the innards of this drive enclosure. If the later, have you measured voltage on the different rails to confirm it is indeed working properly?

It might also be a problem with the CD drive itself. I understand this was an issue with certain Toshiba models, I myself had to replace two XM-5701B from an Ultra 1 and an Sparcstation which were either not showing up on the OBP bus probes or simply not becoming ready and spitting out all types of errors in Solaris.

See, for instance (not my thread).

PS. Also check for proper jumper positions to terminate chain if necessary, sector sizes, etc.
