Greetings!

To be honest, I have never really mixed and matched drives in the empeg. It has always been one pair or another. I think there were some issues about mixing different manufacturer's drives (i.e., Toshiba and IBM), but I have not read anything about two drives by the same maker. I know other people have upgraded to mixed IBM configurations on the board without problem, though. Perhaps one of those people could take it from here...
