[QUOTE="parasbuy, post: 1216344, member: 189066"] Hi All, thanks for your posts over the last couple of months. I ended up bringing the Mac Pro into Apple. Apparently the problem had to go up a few levels to their Head Genius; took a couple of weeks but she is 'humming' now with all three drives in, regardless if I'm in Windows 7 or Mac OS X. If interested, here's the story regarding the resolution. The lower level techs tried their best but concluded that the SMART Controllers of all three drives had gone bad and recommended I get new drives replaced under warranty from each of the OEMs. Obviously, I called "bull crappola" and that the likelihood of all three drives going bad at the same time was remote, at best; and if it was true, that the Mac Pro must have done it and Apple should replace all three drives with new ones. After a bit, the Head Genius gave me a call at home and thought the conclusion was bogus, as well. He ended up testing each drive individually on their tester and they each performed stellar. Replaced the drive control board and still know problems. Eventually, he got to the RAM, pulled them all out, and re-sat the four 4GB sticks just for kicks and, voila, the SBBOD went away. He surmised that for whatever reason, a section on one of the sticks probably wasn't getting the right connection and the computer would get hung-up ever time it was engaged. That was it... nothing more complicated, it seems. Regardless, she's humming and I'm a happy camper. Thanks... hope this helps. Paras. [/QUOTE]
