First, please refer to the pic above.
My problem is that my 40GB Seagate barracuda (shown as Device 0) functions only in Ultra DMA Mode 3, whereas my older Samsung 20GB (shown as Device 1) functions in Ultra DMA Mode 4. I'd like to know how to make it work in Mode 4, as it's faster (66 MB/s). I've upgraded to the lastest Via Hyperion Drivers, on Windows XP SP2. Any suggestions?

Probably, Your HDD does not support the function. Many of them don't even support DMA........................
