DMA replaced by PIO

Gswiss · #1 06-17-08, 11:24

Running under XP-SP2, when we use a single disk, DMA is active and everything is fine.

When we connect a second physical disk as slave on the same Main IDE Channel, both switch to PIO.

We bought a new 80-connector ribbon and tried several different slave disks. No change.

FYI, both dvd readers are on secondary channel.

Could be hardware failure. Try this hard disk in another working pc.
