The errors you were witnessing after attempting to re-insert it into the controller, were they generated at BIOS level within the controller bootup, or in FreeBSD. I'm completely assuming that your running OS was ON these disks, so the former is true. > This is a 4x250G R5 (so ~750G logical) that does have data on it that I > would very much like to recover somehow.

Recover from backup ;) I'm kidding. It's too late for that, isn't it. read on... > I can dig up the old logs (I think) from > when she was firing errors two weeks ago. Yes. Post the logs. If they are extensive, perhaps you could email them off-list, with a notice to the list that you have them in the event others would like to review them as well. > The drive was formatted UFS2 as > one large logical drive in sysinstall. ..so if I understand correctly, you had a RAID-5 with three operational physical disks, and one hot spare?
