Volume Degraded without errors
Hello! I have a ReadyNas 104 with 2 WDC WD40EFRX-68WT0N0 4TB NAS HDs. Out of the blue, the system started to show the 2nd HD as DEGRADED. I have destroyed, reseted the hole system and for...

Replace the disk.
Getting another WD40EFRX is fine, you could also get a 4 TB Seagate Ironwolf. Avoid the WD40EFAX, as it is SMR.

Not a definitive test. You could try testing it with WD's dashboard software. But it's pretty clear that the NAS is not happy with the disk.

That's what I'm thinking, replacing the disc! I've already disconnected it.
Is it possible to downgrade the RAID 1 to JBOD so the unit stop flashing "DEGRADED" all over while I can't afford a new disc? (I'm brazillian, it's very expensive to buy a new HD now... I will have to wait a few months until I can get a new one.- StephenBOct 11, 2022Guru - Experienced User

You'd need to reinstall any apps, recreate the shares, backup jobs, and similar stuff. And restore all the data from a backup.
There is a way to do it with the linux command line (ssh), but I don't recommend going that route unless you already are comfortable with linux. Also, it's best to make sure you have an up-to-date backup if you go that route.
FWIW, you should make sure you have your important data backed up anyway, as it is quite possible that disk 1 will fail while you are waiting.

I'm quite comfortable with linux / unix. If you have a how-to, I would like to try.
I have another backup solution besides nas, so my data is not (so much) uncovered!
