Hi, As you may have noticed on this list, power supplies are very frequently a problem. Just taking what you said, a ST3500630AS 7200.10 disk requires up to 2.8A peak on the +12V line, which is 28A total for 10 disks. The Coolermaster Real Power Pro 750 has three separate 12V rails and each can only go up to 19A. So that might already be the answer, depending on how the rails match up with your wiring. I suggest hooking up a couple of the disks to your old power supply and powering them up separately [1]. If you don't see any problems on those disks then it was likely power related. -jim [1] http://modtown.co.uk/mt/article2.php?id=psumod - To unsubscribe from this list: send the line "unsubscribe linux-ide" in the body of a message to [EMAIL PROTECTED] More majordomo info at http://vger.kernel.org/majordomo-info.html
