So I have a Norco 4220 Server with 16, 2TB Hard Drives, I have 4 of them connected through a reverse breakout cable, and I have 2 AOC-SASLP-MV8 which connect the other 12 drives. SF8087 to the backplane with the same connector. the first AOC card, all 8 of the drives load up just fine. In fact the AOC-Card in the startup sees all of the drives but when I get into windows (7 x64 ultimate) some of the hard drives from the 2nd card don't show up. I have tried to figure out a common factor but there doesn't appear to be any, its not a specific slot that isn't working, it isn't a specific drive that's not working, I really am baffled. 1-3 of them randomly appear but I can never get all 4 to show up. Any Ideas?
