New disk failed after sync. How do I recover?

I'll post that information later today.

As for googling the drive on readynas, I'll do that, but it is on the compatibility list, so I wouldn't think I had to do that.

Okay, so for this drive that failed in the NAS...

                        Raw Value      Value     Threshold     Status
Reallocated Sectors =        0          100         10          OK
Current Pend Sect Count =    0          100          0          OK
Uncorrectable Sect Count =   0          100          0          OK
Command Timeout =            0          100          0          OK

The Seagate site says "No newer firmware available"

So, from everything I'm reading, the drive appears to be okay.

Any ideas why it failed in the NAS?

Should I return it for a replacement?

My only idea is that it failed because it is ST2000DM001-1CH164 - and despite being on the HCL, lots of folks have trouble with them.

That worries me, because I've bought 3 of them to replace the drives I had in my NV+. Two of them are in there already. I only had problems with the last one.

Personally I've switched to WDC red drives.

If you can do an exchange with the reseller, that might be one option. That is, leave the working drives alone, and exchange the non-working one for a WD20EFRX.

We Replace disks at 50 Reallocated Sectors or above, and at above 1 ATA error. Thats if you purchased NAS with disks.
It could be a bad slot - Try the following.
(1)
If you have a known good disk that is compatible with the NAS. Turn the NAS off. Take out all disks and remember their order. Put in that 1 disk in that slot. Go to Factory Default it throught the Boot Menu (http://www.kossboss.com/rnasbootmenu). Dont worry about factory defaulting - I wouldnt have you do something that would hurt your data - the config is on your old disks that are sitting out of the NAS.NOTE: Factory defaulting with 1 known good drive in 1 slot should take no more than 10 to 15 minutes.Anyhow after the boot menu Once you select Factory Default open up RAIDAR and hit rescan until you seee that NAS with the bold Setup comment on the right most column. Press Setup button and do XRAID and hit Apply. If the NAS comes up with that disk we know the slot is good and the disk that you had problems with is bad
To bring NAS back in the way it was: Turn off NAS, Put in all the good disks back in NAS in same order, questionable disk on the Side - not in the nas. Turn NAS on - voila there is your old setup - as if you never did a factory default

Take that disk connect up to PC and run Comprehensive Diagnostic with the manufacturers tools - SeaTools

(3)
Turn off NAS, take disks out remember order. Take questionable disk and put it in known good slot. Factory Default thru boot menu. Go to Raidar, hit rescan once you see nas, hit Setup. Do XRAID if it works it works the disk is good the slot is bad.

If you come to the conclusion the slot is bad call in support so we can check warranty and RMA the chassis.
If you come to the conclusion the disk is bad call in support if that disk came with your NAS - if not buy new disk or call disk manufacturer for RMA

That is the question at the end of the day: Is the ST2000DM001 really compatible with the NAS? Yes, it's on the HCL. But it seems obvious that the Netgear testing did not (and does not) include all the drive submodels.

Kossboss - he's already gone down the seatools route. I agree it is reasonable (though tedious) to test the various NAS slots.

network23 - if you want to do this, you can skip kossboss' step 2, since seatools already is known to pass.

Do you think there is any point to putting it back into the NAS and see if it works a second time?

Well I wouldn't put it back with your existing RAID array - there is too much risk.

Trying it by itself (all other drives removed with the power down) would let you see if the problem only happens when the disk is plugged into slot 3, or if it happens in all slots. To be certain, you'd have to confirm that it fails in slot 3 (with other slots empty) by doing a factory default with the drive in that slot. And then do it again in other slots (particularly slot 1).

Kossboss is thinking that sometimes the NAS hardware fails so that one slot doesn't work at all (or doesn't work reliably). In that case, you'd be entitled to a replacement unit. It is a possibility.
