Do try the usual CD/DVD lens cleaner first as well as some other OS like Linux.

I built a computer out of parts from two almost identical units. I took the hard drive running Windows XP Media Center Ed, the DvdWriter, and the case from one and combined it with the Motherboard running Windows Home Media Center and a CDRW, and power supply of another.
It works pretty good, however my dvdwriter can no longer recognize 8.5 gb discs (either ones burned myself or store bought dvd movies).
I've tried uninstalling and reinstalling and updating drivers. The only odd thing is it does function but when reinstalling the firmware it says "This system is not configured for the "TssTcorp cd/dvdrw ts-h6652L" so no update is required"
I've also tried many of the tips and tricks on various forums for this type of problem.
Do you think it's a conflict between the motherboard and different operating system or more likely the dvdwriter is just spent after many years of use?
