Volume data is degraded
Hi - I see this question has come up before, but I hope you can help with my specific problem. I have 2 x 3TB and 2 x 4TB Western Digital HDDs in my ReadyNAS 104. My usage shows 1.96TB free out of a...
Thank you for your quick and clear response (and the hopefully good news).
I've attached a screenshot - I note it does say "Raid 5" as well.
Does that look as it should? If so, I'll get straight to ordering that new drive.
Yep, that's the normal display for a single failed drive but data still intact due to RAID.
OK, I bought a new 14Tb drive and hot-swapped it for the failed Disk 4, thank you StephenB
While waiting for it to arrive, Disk 3 had been complaining of ATA failures, and on installing Disk 4, Disk 2 appears to have died completely. I've since removed it.
I've now got the following - can anyone advise what to do next?
How do I "remove inactive volumes"?

RAID-5 can't handle 2 failed drives. It might be possible to recover if the failed disk 2 and/or disk 4 can be cloned. But this would be tricky, and not something easily dealt with on the forum. Netgear offers a data recovery service ( https://kb.netgear.com/69/ReadyNAS-Data-Recovery-Diagnostics-Scope-of-Service) - there are others who specialize in this as well.
Yes, I have a feeling Disk 2 died overnight as Disk 4 was getting bedded in.
I'll see what Netgear support have to say about it.
Thanks for your quick reply.
