Dead Drive
Question: I had a 'data degraded' message on my RN314, and the log said disk 2 was failing. I've replaced that, and it seemed to successfully resync, which was great news!
However, Disk 1 status has now changed to FAILED, and is now DEAD.
Ouch!
If I now replace Disk 1, should it resync again, and all will be OK?!
Thanks for any help out there.

Can you download the log zip file, and look in mdstat.log? Perhaps copy/paste it into a reply on this post.
Here is the log file...

Paid Netgear support (my.netgear.com) is the best path, as this is hard to troubleshoot and I don't know of any good guide. You can try to get per-incident support - but you'll need help from the mods ( JohnCM_S or Marc_V ) to get that. Don't get gearhead support, it doesn't cover what is needed.
