I was doing a backup to DVD-R, like I've been doing for a year or so, to a disk that was partially full. It finished the write portion just fine, but when it got to the test (reading back the files that had been written) it said about 25% of the files were bad. Well, stuff happens, right? So I tried it again, (new disk) and this time, it wrote all the files, but when it got to writing the lead-out, it stalled. Tried it again, new DVD, and it didn't even recognize the disk.

Tried to copy some files (any files) to a CDRW, and it didn't recognize that there was a disk in the drive. (Tried 3 different CDs.) It can play CDs and DVD movies just fine, audio and video.

Powered the computer off and on, checked cables, no help. Anybody got any ideas? Is there a new DVD drive in my future? This thing's only 14 months old!

Thanks a lot.
