ReadyNAS Pro Pioneer Drive fails to resent

I have a Pro Pioneer configured as raid 1 with 3X2 drives.  Running raidaitor 4.2.28.  I replaced one drive on a volume with an identical 3tb drive.  Tested and passed.  Flashed resync for about a minute and just volume unprotected.  Front view says volume is dead.  Tried rebooting and nothing happened, volume unprotected.  Removed drive and reinserted with same result, drive passed testing, started resync and then nothing.  No message or anything.  

 

Is this just a dead drive that I need to replace?

    I already ordered another Seagate St3000DM001 disk before I received your reply.  I have had good luck with the Seagate disk, first failure in 5 years with 9 disks.  I will look at the others in the furture.  I put the new disk in and it synced up just fine.  The disk that failed was a backup disk that had been used before and was good when I took it out.

    Can you send in your logs (see the Sending Logs link in my sig)?

      I sent the logs in a separate email as instructed.

        This could well be a bad disk.

        Have you tried removing the disk, hooking it up to your PC and testing it using SeaTools?

        Btw, I would not recommend purchasing ST3000DM001 disks. These are known to have very high failure rates. Going forward I would get SeaGate NAS or WD RED disks. The WD RED 3TB is on the hard disk compatibility list: http://readynas.com/hard_disk_hcl

        Also, you have a ST2000DL003-9VT166 disk with CC3C firmware on it. This model disk is known to drop out of arrays in some cases when it shouldn't on firmware older than CC3D. You can update this disk from CC3C firmware to CC3D firmware.
