Oh, to add insult to injury, the issue came back with the new SATA cables, but only on one drive. I think one of my Hitachi drives is dying but the WD drive that was "dead" had a dying cable because I brought it to work with me, plugged it into one of our servers with an eSATA dock and SMART said that my 4 year old drive that has been running for 25000 hours is in fine shape . I think it might have been a double issue. Once the wife wakes up and I have access to the tower, I'm going to remove the drive from the raid and check the SMART logs. I'm just hoping that it isn't the RAID drivers (last updated when X79 came out. ) or the SATA controller itself. You know, You would think that Intel's Rapid Storage Technology Enterprise would be able to check and run SMART tests on drives in your raid. My Phenom II 940 motherboard with an nVidia 750a SLI chipset was able to, and you could schedule it to run regularly too. Not to say it is bad, it's just a little lacking for a server-grade fakeraid RAID solution (C600 chipset.) I do say though, RSTE rebuilds RAID-5 almost twice as fast as nVidia's fakeraid which is a huge plus.
