I have an older mobo which only support UDMA 66, I have a master and a slave drive, both ultra ata 66 on the primary channel. When I check the UDMA mode in device manager, I'm at mode 3, should I not be at 4? I have 2 DVD drives on the secondary channel showing a UDMA mode of 1, again, shouldn't it be at 2? Any info or ideas would be greatly appreciated. Thanks much!!
