I just bought a two channel raid controller (100/133) and two 80 GB drives (100). They only supplies one ribbon so I installed the two drives on the one ribbon (one being master and the other slave). Hey presto, it worked (meaning I could set up RAID 0). Not being happy with that and wanting the extra speed from using both channels, I bought an additional ribbon that is 133/100. I installed it and took one drive from the orignal ribbon. Firstly, I tried both as masters as I understood this is what you do. Secondly, tried one as master and one as slave. Thirdly, swapped that around. None of it worked as only one drive was picked up each time. Any ideas?
