I'm giving my Dimension 4550 to my hubby when my new Vista Dell arrives this week but now, all of a sudden, the NEC DVD_RW ND 3550A won't burn. It worked fine until it decided not to burn with the message "no disk in drive etc" even though there was a disk. I tried other disks, I uninstalled with Device Manager and rebooted, I opened up the case and disconnected the drive and rebooted, shut down and reconnected the drive and rebooted, checked that DMA is enabled, ran the Help and Support Troubleshooter which says the device is working properly. I took the disks I wanted to burn to another computer and they burnt fine, but not on my NEC. It can read disks and play DVD's and CD's, it just won't burn.  

 

Any thoughts?
