I have 2 HDs:
Maxtor 120gb 7200rpm 8mb
Maxtor 250gb 7200rpm 8mb
if I put 120gb & 250gb both in the same IDE channel (Primary), then the 250gb would be running in PIO mode and the 120gb running DMA.
But if I put one in Primary and one in Secondary IDE channels (both as Masters), they'll both be running DMA.
Can someone tell me why I can't run both HDs on the same IDE channel in DMA?
All channels are set to "DMA when available", so I don't think it's a settings issues. I'm running WinXP SP1a.
