Hmm, not sure. How do I tell if it's a JMicron connection? You're talking about the underlying chipset here, right? As far as I know, all 4 SATA ports on the board are run by the same NVidia chipset. All are being used, too, as I have 3 hard disks and the DVD writer installed. Two of the disks are setup for RAID 1 (mirroring), so I cannot move those around. Could it be that since the SATA mode is RAID (as opposed to IDE or AHCI) this is causing a problem for the DVD writer?

I'm trying to burn a DVD ISO to a DVD-R disc, using a Sony Optiarc drive. It fails to write some sectors and complains about "No Additional Sense Information". I updated the firmware on the drive to what I believe is the latest. And I believe I have the latest drivers for my motherboard (Asus P5N-MX). Still no luck. Judging from other posts, it appears to be a hardware/driver problem, but I'm not sure which parts may be causing the problem. Anyone have any ideas on how to solve this problem? The log is below.
