History: I’ve had some trouble getting Ultra DMA to work with my new DW1640 (Benq 1640 rebadge), first swapping the cable for an 80 conductor, then moving from secondary to primary IDE channel (VIA 686B southbridge). Finally, I did get it working on UDMA mode 2 instead of Multiword DMA mode 2. I can read from the drive using Windows (98SE) explorer, and everything seems fine.
However, if I try to burn or run a CD Speed benchmark in Nero, the program hangs and the drive locks up. The locked drive won’t allow Windows to shutdown normally, and I have to hit the reset to reboot. When I back the speed back down to MWDMA2, everything is fine again.
Has anyone else had problems with Nero and UDMA on a DVD burner in Windows 98SE (is anyone else out there still using Win98)?
