5005 giving me a problem

I have had my Lite on 5005 for about 1 year now and have had no problems with it. I have not done any of the hacks to it yet( just be lazy really) well today i think i have had a drive failure. The unit will not reconize any disks that were recorded and finalized or not finalized on it. The ones that were not finalized try to prepare again. Out of curiosity i tried a DVD movie(original and it plays fine. Is it time to replace the drive?

could be but first try a DVD cleaning disc, fw upgrade to oo98 hacked, then it you still have problems attach a DVD burner from you PC for a test

Thank you, the cleaning actually worked. I am now going to find the hacks and install them. Again thank you for ur assistance
