Replacing a failed drive in a Qnap box

One of my customers has come to me with a QNAP Nas that has a failed drive. The QNAP is a 4 bay and has 4 x 2TB WD Red drives set up as RAID 5.

I have removed the failed drive and fitted a new one, but the NAS is still running in degraded mode. We have rebooted the NAS, upgraded the firmware and removed and reinserted the new drive, but nothing seems to work. The System Logs report the new drive as failed and the drive status is 'Disk read/write error'.

I am currently running a Bad Block Scan on the new drive.

Can anyone offer any advice as I'm now wondering whether the new drive is faulty or whether the QNAP is faulty.

Thanks

You should be able to recover the array through the storage manager.

None of the actions are available in Storage Manager because it's listing the error with the disk. QNAP say that the RAID is meant to rebuild itself when restarted with a new drive in but it's just not happening.

System logs show:

[RAID5 Disk Volume: Drive 1 2 3 4] Start Rebuilding
[RAID5 Disk Volume: Drive 1 2 3 4] Rebuilding Skipped
 
The drop down list in the RAID Management tab doesn't let you use any options at all with the array selected?
 
Its ages since I had to recover a RAID on a QNAP box but I seem to remember having to go into RAID Management, selecting something and using the drop down menu at the top left to do something before it would "automatically" rebuild the RAID which was either the spare or recover option and I think recover is just for accidental disconnection of a member disc not for a new disc but I'm a little vague on it. I'm 99% sure that you have to configure a new drive as a spare before it gets automatically pulled into a degraded array.
 
Hmm reading the docs suggests it should do it fully automatically if the array is degraded and you straight swap for an identical or higher capacity drive and if it doesn't its not seeing the drive as an appropriate replacement. Don't have that much experience with it but I know it didn't automatically do it the one time I've had to sort a member disc failure.

In Volume Management it is listing the replacement drive but showing a read/write error which makes me wonder if it failed to format the drive correctly. If the bad block scan doesn't fix it, I will pull the drive, format it in a PC and then reinsert the drive and it should hopefully reattempt the format.

FYI: The original drive was a WD Red 2TB and we have replaced it with an identical drive.
 
Quick update. Left the Bad Block Scan running overnight, got into work this morning and the system logs show:

[RAID5 Disk Volume: Drive 1 2 3 4] Add drive 1 to the volume failed.
Plugged drive failed to work.
Drive 1 plugged out.

Then in Storage Manager, it is showing HDD1 as not existing.

Now going to run WD Diagnostics on the drive.
 
If the "new" WD drive is the warranty replacement, just bin it.

I had 3 warranty drives for a 3month old 3TB red that failed and EACH OF THEM failed to low level format in 2 different PCs.

The warranty drives they send out seem to be failed drives that have had smart data reset and sent out again.
 
Seems to be common sadly with most non-enterprise lines of drives :S almost regardless of manufacturer - pretty bad.
