my reason for wanting this was redundancy. Sometimes Im using too many sups (one for biab, one for protools, etc) and then some software cant find the hardrive. So , I reinstalled biab putting 80 gigs of wmas on the c drive for a idiot proof solution, so I don't get embarrassed when something doesn't work in front of my producer. If I can switch them, then I'll go home and play around with the hard drives until it works. Thanks for the imput.
