Plextor PX-708A CD problem

[howardg]

My Plextor PX-708A DVD writer cannot recognise CDs whether just to read or burn. The drive can however read/burn DVDs. I have the latest firmware but this does not solve the problem. Any ideas very welcome.

This should help to diagnose the problem.

How do I run the self-diagnostic tests on the PlexWriter PX-W4012A, PX-W4824TA, PX-W5224A, Premium and PX-708A drive?(HW00008)
