Hmmm, I had a look and I think it is set to auto.
That doesn't seem to make much difference though.
I had a look at another thread here which said to delete the Secondary IDE channel and then search again for hardware. I did this and got a blue screen/reset, but the Secondary channel is back again with the same settings when I check in Nero Info
The only thing now is, when I right click on it in the Device Manager and go to Properties, the "Advanced" tab is no longer there....
Another thing - Nero tells me that the ASPI layer is corrupted, although the Nero ASPI is fine (there are two in a drop-down list in Nero Info).
