I got an annoying problem with my nForce4 chipset: usually I don't reboot very often, but now I'm forced to reboot after burning 4-5 DVDs... this is because WinXP downgrades my BenQ DW 1620pro from UDMA2 to PIO-mode, which makes working impossible while burning (not to mention the bad burning quality cos of permanent buffer underruns).
The nForce driver reports "transfer mode has been downgraded due to excessive errors". I replaced cabling, etc. I think this is a hardware incompatiblity. I already read that other users here have the same prob, but no solutions were given.
Maybe there is a way to disable this downgrading?
