My burner is stuck in PIO mode. I have been unable to reset to get DMA working using the normal methods. Looking for help and suggestions.
In my registry, under HKLM/hardware/devicemap/scsi/scsi port 1, the DMAEnabled value resets to 0 whenever the computer attempts to detect new hardware or changes. I believe this is why the drive reverts to PIO even though my transfer mode is set to “DMA if available”.
After hours of experimentation, here’s some of what I have tried so far:
manually changing DMAEnabled to 1 in registry (always resets to zero)
uninstalling/reinstalling IDE controller driver
using alternate IDE controller driver
manually deleting the checksum in the registry
adding “ResetErrorCountersOnSuccess”=1 to registry
removing and reinstalling the drive after doing above steps
physically replacing the drive (lite-on) with a different drive (hp)
no results. I am trying to avoid re-installation of windows at all costs. Any suggestions?
edit: I am using windows XP w/ SP2 and all latest patches. My bios does not allow control over drives (dell laptop). I also can not try replacing cables as there are none. DVDFab’s magic “DMA Reset” button did not work either.
