I've had my LiteOn for about eight months now and have not had a problem until recently. I burned a couple of CDs using Fuji media (TY) at 52x and at the very end of the disc, buffer underrun would kick in and then the lead out would be written. The last file would fail CDSpeed's scandisc, although it was readable in Windows. Other times, about 3/4 of the way through, the drive would spin down then finish the rest of the disc (p-cav).
I decided to try burning a CD with CDSpeed to see what was going on. This is what I got: .
This is one CD out of a 100 pack and the first ~50 have been problem free, but I've been having problems with the past five or so. I haven't been able to test another batch/brand of CDs yet, but is this probably a media problem?
