Wow I should check this more often, thanks for all the replyâ€™s.
After the original problem I changed my BIOS from CS02 to CS0C (the latest) and still have a problem.
I moved the drive to another PC with an older version of Nero (5.5.something) running and it still wouldn't read CDs. It would read CDs before the crash but wont now.
It seems like Nero has caused a hardware problem with the drive???? Something that I wouldn't think was very likely let alone possible.
After some investigation I don't think Nero was to blame I think it would have happened with any CD Burning software, I think the drive has been manufactured with a potential problem and burning a CD causes that problem to come to life. Sounds strange but its the best and most likely thing I can think of.
Lite-on stuff used to be really good, I guess times change.
Iâ€™m going to do a change over with the shop, only problem is that I ordered it online so it could take a while. Ill let you know how I go when I get the replacement drive.
