RN424 , 4x 8TB WD Red Plus failing after 120 days?

Just a quick update – I got in touch with the vendor (from where I bought the RN424 and the 4 HDs), they recommend doing the RMA directly with WD, which I did, got the reply with the RMA number and RMA Date: 08/11/2021 03:51 PM) and sent them my failed disk that afternoon, WD should have received next day.

Update #2  WD dispatched a replacement disk on 21 August (Saturday morning @5:02). unfortunately UPS failed to recognise the tracking number during the weekend, and also on Monday morning, but on Monday afternoon I received more mails following the despatching, with delivery expected by the end of 24 August.

Update #3 Received the replacement from WD on Wednesday 25 August 2021~9:00 am

I think I have read somewhere StephenB saying that he tests his replacement HDs, so I put on test using DLGDIAG – Estimated time required ~66h

Update #4 Friday 27 ~19:30. DLGDIAG fails the replacement HD  “Too many bad sectors detected”. I immediately filed a “Question” on the WD Support (could not find any specific way of “connecting” to the RMA).

StephenB, Thank You !!!

Update #5 Wednesday 1 September ~19:05 “Incident Update” reply from WD

“……..I am sorry to hear that your replacement device was faulty well; relevant teams are informed about this issue and we will continue assisting you until we provide a solution.

It may take time to hear back from relevant teams about how to proceed but we will do our best to conclude this issue as fast as possible. ………”

Update #6  Thursday 2 September 18:05 (UK time)

On 30 July , when the incident occurred, the situation was:

RN424 has ~14.03TB used and 7.74TB free.

RN214a has ~7.71TB used and 3.19TB free

RN214b has ~4.22TB used, 4.97TB of snapshots and 1.77TB free

On 2 September, the situation is

RN424 – unprotected volume, NAS is offline. I did not copy/move any conspicuous amount of data, just  the end of the folders in use, so the usage can be considered to be the same as above

RN214a – 8.35TB data, 138GB snapshots, 2.42 TB free of 10.90TB

RN214b – 5.73TB data, 955.54GB snapshots, 4.24 TB free of 10.90TB

Update #7 Monday 4 October (yes, it has been a month)

WD is still trying to sort out a replacement disk for me – there have been some wishful emails on their part expecially because my spare NAS has gone to 30% “space left”, then to 20% “space left”.

But I cannot wait any longer so I bought another 8TB WD Red Plus, CMR 7200rpm (as well as UPS, which was needed)

Update #8 Tuesday 5 October – Parcel delivered Hurray…..

Unfortunately I just checked and the WD80EFBX (supposedly the replacement for the WD80EFAX) is NOT in the compatibilty list…….
