The drive itself wasn't actually dead, I did some running tests on it and it spun up OK in an enclosure and then in another machine. So I tried to put the drive back on the array and it doesn't believe in having data anymore. This is a 4x250G R5 (so ~750G logical) that does have data on it that I would very much like to recover somehow. I know this is very likely a fruitless endeavor, I just need to try. OnTrack and other recovery places are just too expensive for this. I can dig up the old logs (I think) from when she was firing errors two weeks ago. The drive was formatted UFS2 as one large logical drive in sysinstall. Hope that's helpful. Thanks for the reponse. -- Ryan
