When I switch on DMA on my optical DVD-RW drive which supports DMA cause I used it in my old computer, now I get these errors all over the CD/DVDs that there is an error in the I/O when I try to access some files and folders.
When I switch it to PIO it’s solved again, but PIO isn’t what I want.
It started when I built my new PC, my old never had this problem. It’s a ABit KN8 motherboard with NForce4, I just can’t get the damn thing to work in DMA like it’s supposed to.
Now I have a few questions on this:
My only IDE unit now is my optical drive, and it is Primary Master on Primary IDE-Channel. My HD is on a SATA channel.
Can it have a bad effect to have my optical drive on the primary IDE-Channel as master?
This is my system:
See anything strange? Well I do, why to I have 3x of all my channels? Shouldn’t I only have 1 Primary IDE-Channel, 1 Secundary IDE-Channel…?
What is this weird phenomenon causing this DMA failiure?
