optorite cdrw won't read backups on only one pc

[waitman]

OPtorite 52x burner will read original disc fine, but will not read the backup. I have tried this drive in 3 other systems and it reads the backup fine. Using winxp. The pc that won't read it has a 1 gig duron/k7s5a. I have tried another cd reader in this machine and it will read the backup fine. What am I missing here? thanks in advance.

Wonder if it is possible that DRM has something to do with this, Haven't tried another burner in this machine, to try and read this backup. This is the only machine that has a newer version of the Windows media player. Seems I read something on this a while back. Any thoughts anyone? Thanks

DMA enabled on the storage channel of the offending Duron? While installed on the Duron, does the drive read other pressed CDs?

Thanks for the reply airfoil. Yes DMA enabled and it will read all other pressed disks. Only has problems with the backups.
