Yep, I'm afraid so. I did a temporary retreat and decided to put the beast back together because I need to use it. It really doesn't make sense to me why I am having this problem. I don't mean to take joy in your difficulties but It is comforting to know that somebody else has experienced problems with this. Somewhere I have a list of drives that are supposed to work and it is a list expanded far beyond the original list in the manual. If I find it are you interesed in seeing it? I have this strange feeling that I am going to stumble onto that list and some drives as soon as I get this beast back together and in the rack in my studio. It has been out far too long now and I have need for it. BTW, I think that list came from DPS before they were absorbed into another company.
