Not what I would expect from a brand new drive!!
Does anybody have any tips on how i can work out where the fault
lies here? I wouldn't expect controller with so many other drives
working, and what on earth is the proper technique for replacing a
drive that failed part way through a resilver?
I really believe there is a problem with either the cabling or the
enclosure's backplane here.
Two disks is statistical coincidence, three disks means, it ain't the
disks that are bad (if you checked and there was no recall and the
firmware is correct and up to date).
Fix the real problem and the disks already in place should resilver
without further interruption.
