Is it true that every time there's a major 'fault' on a cd/dvd drive the DMA will drop one, i.e. dma 6 to dma 5 and so on, until it defaults to pio mode? Also will the only thing that can reset this be a full re-install of the OS?
Yeah, I've had some luck, done a bit of research, if for example there's some kind of burning error, the os will drop a dma level, if the fault keeps re-occuring, the the drive will eventually drop to pio mode, of which the only solution to revert back to dma is a full reinstall. Apparently.
