My CD RW (Matshita CW 7586) has suddenly stopped burning CD's. I use Nero and have had no problem before. I have tried the CR-RW in another computer and confirm that it works. The Sytem properties also confirm that the device is working properly.

I have also tried reading CD's I had previously burned with IN CD UDF FORMAT, but the CD-RW will not recognise that there is a disk in the drive.

Any ideas please?
