Speaking from a desktop PC and XP,
I just had some posts bitching about DMA 2.
My PC will drop to that mode at the slightest hint of a read error or it seems.
then it burns very slow. [pisses me off when it does that too.]
It should be at Ultra DMA 4 So I end up having to un-install the secondary channel which is home to my Plextor 16x Burner and Rom and reboot the PC.
It then goes back to Ultra DMA 4.
Don’t know if laptop works the same.
If it does, go into your device manager and un-install your secondary channel [U]IF [/U]that is where your burner lives.
Don’t know about laptops with Vista but I DO KNOW that multi read DMA 2 is definitly too slow in a desktop PC with the stats you have cause I have 2 gig memory, XP2, 2.8 processor and 32 bit.
