Left hard drive failed, but works fine in PC

I have a RAID 1 array of two Seagate ST31000340AS 1TB drives. One had the bad firmware, and was upgraded. I've been using 1.08 beta 5 for maybe 4 or 5 months with no problem. The other day I rebooted the DNS-323, and when it came back up I got 2 emails. One says the volume has degraded, and the next says Left hard drive has failed. It does not show up in dmesg. I took it out and put it in a PC, and it works totally fine. I put it back in and I just get those emails every time.

Any ideas?

Re: Left hard drive failed, but works fine in PC

sometimes the dns behaves wierd. are you running raid1? then i'd say backup and reformat (maybe reformat in pc, just to make sure)

Oops, I forgot to mention that. I did format the drive in the PC and used it to make sure it was working fine. Still no luck when I plugged it back in.

I had a similar issue in the past with the same disks and it has cleared after a couple of DNS-323 restarts.

If it does not work for you first of all read the smartlog of the affected disk to rule out a genuine prefail condition and then reassemble the array from the command line using mdadm.

Re: Left hard drive failed, but works fine in PC

skydreamer are you still using your DNS-323 with those drives? I put the drive in the right bay and everything is working fine. There are no S.M.A.R.T. conditions. I guess the controller just went bad? I've tried power cycling the device several times and no luck. I'm wondering if I should try to get it repaired or just sadly toss it in the garbage.
