I have a new Dell 4600 PC with 2 Hard drives (both new 80Gb and 120Gb) and a DVD+-RW.
I have the DVD+-RW on the second IDE cable and it runs happily in Ultra DMA mode 2. I have the 80Gb as my master drive on the first IDE cable and it runs happily in Ultra DMA mode 5.
If I add the 120Gb hard drive to either cable as a slave it runs in PIO mode (which ofcourse I don’t want). But if I add it as a master on the second IDE cable it runs in Ultra DMA Mode 5, but the DVD+-RW will then only run in PIO mode on the slave.
How can I get all three to run in Ultra DMA mode?
I have tried deleting and reinstalling the IDE controllers.
