Occassionally CDRW drives don't like commercial CDs; I've got a sony cdrw, and it barfs on some game cds, but not mohaa or mohaa-sh

I think it could be a chipset problem, but it could be the drive, or possibly even the disk. If you can get it installed somewhere else, and don't have problems with your other disks, then I'd say it could be a chipset issue, but make sure you know what your motherboard chipset it before doing any firmware updates otherwise you might cripple your system.
