ReadyNAS 102 Power LED flashing after power failure
Our ReadyNAS has a single factory supplied drive in bay 1. We had a power failure that has left the ReadyNAS 102 with a flashing power LED.
Initially the unit would not shut down pressing the powe...
You might try RAIDar 6.4, and let us know what status it sees for the NAS. https://kb.netgear.com/20684/ReadyNAS-Downloads
RAIDar 6.4 says;
Status: Previously formatted disk(s) detected (Dirty Disks)
Firmware: 6.9.2
"The disks installed on this ReadyNAS system are formatted in a file system that the system does not recognize. You must reformat these disks in a recognized file system to continue set-up. reformatting disks means that you will lose any data on them. Click Format to continue."
Wow! That's what happens after a power failure!! I can't get the device to respond in any way, but RAIDar will reformat the disks anyway? There has to be another option to retrieve the data off this device. Is the Data still in ReadyCloud?

ReadyCloud is a VPN that provides access, it doesn't include cloud storage.
What you could try is getting the Paragon Linux-for-Windows package (~$20): https://www.paragon-software.com/us/home/linuxfs-windows/ That does support btrfs - if the file system isn't corrupted it should be able to access the data volume if you connect one of the RN102 disks via USB. Though I haven't tested this with RAID-1 myself.
ReclaiMe RAID recovery software is another option, though much more expensive.
You could also try paid Netgear support (my.netgear.com).

Bad things can happen when cached writes are lost. I always recommend using a UPS with all NAS. FWIW you should also have a backup plan in place, since RAID alone isn't enough to keep data safe.
I was able to copy mission critical data from two computers that access the ReadyNAS drive regularly and have the ReadyCloud symbol in favorites in Windows Explorer to our older NAS drive. Not sure how that worked, but it did.
I then purchased and installed Paragon Linux-for-Windows, put the 1Tb drive in an external drive box and connected it via USB. Paragon Linux-for-Windows was unable to read the drive under any circumstances (software did not "see" a drive). Since it could not "see" a drive in the external box, it was unable to format or provide any other services.
I was able to put a 100Gb drive in Bay 1 and format it. I then put the corrupted 1Tb drive in Bay 2 and it showed up as present, performed some internal magic, and is listed as 1Tb volume, but I could not access it, nor could I format it.
I'm now thinking that stuffing the 1Tb drive in a Windows computer and reformatting it will help it to become visible when it is returned to the NAS Bay 1. From there I could reformat it for NAS use and reload our data...
When I get this back in service I will have an appropriate recommended UPS for it...
Any other advice?
