RN10400 - multiple failed disks or failed NAS hardware?
Using latest firmware and 4 WD Red 4TB HDDs in RAID5 configuration. NAS fell on its side (vacuuming accident) and overnight registered 2 failed disks and a dead drive. Am currently doing HD diagnosti...

Try the fast write-zero test in lifeguard - that will remove the partitions. Then put it back in the NAS and power it up, and see if you get a different result.
Impressive, StephenB ! I did as you suggested, and instead of booting into Legacy Mode, the NAS appears to be booting normally. I will go ahead and run the other tests as suggested (keeping my fingers crossed!) and post the result.
Thanks very much.
Final (hopefully!) update: after running through the tests suggest by Sandshark it appears that all drive bays are functioning properly. I added another old but still serviceable HDD (on which I first performed the quick erase as suggested by StephenB ), and on bootup the NAS is working to expand the existing JBOD. I can now go ahead with some confidence to begin to replace the failed HDDs. Thankfully, the last time I had a NAS hardware failure (2015, when I upgraded to my current NAS) I also learned the hard way that a NAS isn't a backup, so I have a complete backup of all the data lost in my sad vacuuming accident. :)
Many thanks again for your prompt and capable assistance.

Well, I think that's probably your best case scenario. If the NAS had been off, the drives may have had a better chance of survival, especially if the floor is carpeted. But spinning platters aren't normally going to take that.
"Sad vacuuming accident" is not a phrase I thought I'd ever hear.
