Default DVD won't stay in DMA mode

One hard disc attached to the motherboard's SATA port, and one DVD/CD
burner attached to the regular IDE port. Every so often, I check and
discover that the DVD drive's controller has "fallen back" from DMA
mode to PIO. I get it back to DMA mode by deleting that errant Primary
IDE Channel from Device Manager and letting Windows redetect it.
Eventually, though (days, weeks, I haven't figured the pattern out
yet), it lapses back to PIO.

Can anyone suggest what might be causing it and perhaps a cure?


Yeah, if you have errors reading with the dvd, windows automatically
downshifts your dvd drive to PIO mode. DVDFabdecrypter, which has a
free version you can download, has a nice button in the settings
section to "reset DMA". Saves you a bunch of time. Helps with
troublesome scratched disks that won't read right.

Another example of microsoft never fixing it's problems even though
it has had all the time in the world and all the resources to do so.



That would be a drive problem NOT windows or MS.
