Thanks for the speedy reply, Patio.
The drive is only 1 and a half years old. I don't use it too often.
It's gonna be quite a struggle for me to try the drive in another machine. Is there any chance something may have been deleted from my windows system folder? I had a "system optimizer" program a month or so ago which may have deleted files.
I've also noticed that WMP crashes when I try to play a dvd...
