ReadyNAS 4220 doesn't recongize new drive

Our 6-month old 4220 had a drive fail. It was one of the included drives (6 bays were occupied when the unit arrived) so netgear dispatched a replacement drive to us. We pulled the bad drive (drive #4 per web admin) and noticed we didn't get a hot plug alert in the logs. We installed the drive Netgear sent, again, we didn't get a hot plug alert in the logs and the volume didn't start rebuilding. We're running in RAID 6 X-RAID. We have a couple of older ReadyNAS units around and we're used to seeing the OS respond immediately when a drive is inserted or removed.

What are we missing toward getting the device to integrate this new drive into the volume.

It's 6 2-tb drives, by the way, and the OS is fully patched to the latest RAIDiator.

    Are you using X-RAID?

    What do you see for slot 4 in the web admin interface?

    Did you make sure the replacement disk had no partitions on it before adding it?
  • Yes, it's RAID6 and X-RAID. In the web admin, bay 4 shows a red LED. When I hover over it it indicates disk state is "failed". Temperature is "-1". It still indicates it's a Toshiba MK2002TSKB drive even though the replacement drive netgear sent is a Western Digital.

    We didn't put the drive into a computer before putting it into the ReadyNAS...since it came from Netgear we figured it was ready already.
  • Well, that bad drive which has been replaced now shows as type "unknown" ... but health is still "degraded" and it appears it hasn't started rebuiding the filesystem.

    Have you tried removing the new drive then putting it back in again?
  • Yes, tried that also. The green LED lights when the drive is inserted, but it shows no activity flickers like the other drives do.
