RN424 , 4x 8TB WD Red Plus failing after 120 days?
This problem is with a RN424 with 4x 8TB WD80EFAX, all identical HDs purchased at the same time as the 424. The system has 6.10.4 Hotfix1 and has been up for 120 days, I had not even transferred all ...

Status.log simply says
[21/07/30 12:20:38 GMT] warning:disk:LOGMSG_DELETE_DISK Disk Model:WDC WD80EFAX-68KNBN0 Serial:VGJL3SDG was removed from Channel 2 of the head unit.
[21/07/30 12:20:41 GMT] warning:volume:LOGMSG_HEALTH_VOLUME Volume data health changed from Redundant to Degraded.”
(yes I can PHISICALLY remove the disk and test it)
Is it possible for the RN424 to “misdiagnose” an otherwise healthy disks or to suffer an hardware fault?
Disks can fail at any time, so it would be useful to test it in the PC.
The bay in the NAS might also have failed - if you have a spare disk, you might try doing a factory install (with only the spare disk inserted, in bay 1). Then power down and move the disk to bay 2. Power up, and make sure it works. If you try this test, label the disks by slot as you remove them.

But what should I do now
- a) should I switch the RN424 off and take it offline? I can copy the few folders I would be working on RN214B and continue there for some time.
- b) should I MOVE data back to other NASes freeing space (but that would not do anything, the Volume is degraded because one disk is missing, it will remain degraded: the only advantage would be that – if there is another HD fault, I would have lost less data – mott point, maybe.
I suggest running the disk test on the RN424 before you copy new data onto it (look on the volume settings wheel for the disk test). That will take a while, and you can test disk 2 in a Windows PC in parallel. Once you know the disk health, you can sort out the path forward.
Since the volume is degraded, the data is at more risk than your other NAS. If a second disk fails in the RN424, you will lose the data on it. So finding a way to back up the critical data on the RN424 would be prudent.
Do you have a backup plan in mind for the RN424? Ideally you'd move everthing on to it, and use the RN214s as backups.
I meant"Disks can fail at any time, so it would be useful to test it in the PC. "
OK - "hot removal" from the 424?
Sorry, ignore that "I meant" before the quote from Stephen B..

Even if it's healthy, its out of sync with the array. So hot removal is fine.
The disk is SO dead that the WD utilities (neither Lifeguard Diagnostic DLGDIAG 1.37 nor the “Dashboard”) could not even see it.

Victoria also saw it, as fail it immediately too.
On the 424 I run the extended disk test as adviced. The test completed on Saturday afternoon. I received an email stating that it had been completed, no mention of any Warning or Errors, I presumed it was ok, but I just downloaded the logs, and in volume.log, the last line reads:
“data disk test 2021-07-30 20:54:30 2021-07-31 13:49:00 pass”.
The other advice was:
“The bay in the NAS might also have failed - if you have a spare disk, you might try doing a factory install (with only the spare disk inserted, in bay 1). Then power down and move the disk to bay 2. Power up, and make sure it works. If you try this test, label the disks by slot as you remove them.”
Do you mean a factory default as in
or via Option 2 in the boot menu (P97 on the HM manual) – (I presume it is the same operation)
I guess that it would format the ”spare disk” (I don’t have a free one, but I suppose I can re-clone one 50Gb hd with a spare W7 copy I have)

A factory default is one way. If the spare disk is unformatted, you can just power up the NAS with it installed, and it will automatically do a factory default (no boot menu action required).
It would be destructive.
Not sure if you need to do this, since you found a failed disk.
WDC will likely give you a recertified drive, though given the quick failure you might be able to talk them into a new replacement. You could also see if the seller will exchange it (unlikely given the 120 days, but maybe worth a shot).
Apologies, I thought I posted the message (within the “==”) last week, but I must have prepared the reply but NOT pressed the “Post” button.
Then, of course, I was checking the mails for eventual replies which never came. Sorry !

Update – I eventually managed to find a free-ish SATA disk on some PC, backed it up, and low-level formatted it. I am just about putting in the RN424 in Slot 1. I imagine it should do a factory default automatically; after that I will switch it off and try the other slots.
I am having problems posting my replies. I posted the one below 3hours ago, and it never seemed to appear, but I only noticed 1h ago. Lets try again.
