I have tried re-configuring my pc to run with a serial ata hd. This has meant that I have my dvd rom and lite on cdrw as masters of their own ide channel. I did this in the hope of removing any errors and reasons for why my cdrw did not work previously. Since reinstalling windows i had a go a writing a cd with all my newly collected up-to-date drivers. I burnt the cd at 52x and it worked fine. However, I just attempted to write another cd and it failed and gave a power calibration error!
Summary of components:-
Nero 5.5 express
