Here is the computer spec:

Running 2 plextor 712A
-in the device driver I have 2 Primary IDE channel and 2 Secondary IDE channel
-the 2 plexotr is connected in IDE1, while 2 HD is connected into IDE0
The master plextor 712A is burning fine, however, the slave one will not burn more then 2X.

1st Primary IDE channel refer to A easy reference
2nd Primary IDE channel refer to B
1st Secondary IDE channel refer to C
2nd Secondary IDE channel refer to D

All of the IDE is set to DMA if available, however only the ‘B’ is on UDMA mode 5, guess this is the HD. And ‘D’ is in UDMA mode 2, while other is Not Applicaple under current xfer mode.

Any help or recommendation guys? As before my plextor works fine. I have try switching media also but no lucks, its the DMA problem but i can’t force it to be in DMa on both only 1 now. Also i have check the biios its auto .
