Or could it be the burner. Not too many problems for a year or so But recently, I was doing a set of cd-rs and on about 3 of 6 attempts I have had failures, with the message "SCSI/ATAPI command timeout error". The process seems to stall at 8%, and I've had to use reset, which generated a scan disk prompt, which on each occasion found an error : "Drive boot area contains damaged or invalid" stuff. It offers to correct the error, which I have permitted. The last time however, the next burn attempt failed again. The computer has Windows ME, and some light Nero version. I am using Verbatim disks, which i understand to be among the better quality. I've turned that computer off for the night. Any ideas or suggestions? Thanks.
