Hi,

this is what i have

Dell 8400
P4 3.0 GHz
512MB Ram
ST340014AS - 40gb drive that came with it on Primary IDE Channel as Master (DMA is on)
WDC WD2500JD-00GBB0 - 250gb drive that I added on Primary IDE Channel as Slave (DMA is OFF)
Lite-On DVDRW LDW-811S on Secondary IDE Channel as Master (DMA is ON)
BenQ 800@822 ATAPI DVD DUAL 8x4x12 on Secondary IDE Channel as Slave (DMA is ON)

Now my question is how can i enable DMA for my WesterDigital 250gb hard drive?
I already tried all the basic stuff, like go into settings and enable dma under Primary IDE Channel Properties, and Device 0 and 1 are both showing Ultra DMA Mode 2.
I tried to go into regedit and delete the entry and that still didn't work.

But under Nero Info tool, my 250gb hdd is showing DMA is OFF????

Anyone?
