RN104 data-0 inactive since April, still stuck after PSU fix - need assemble advice
Hi all, I have a ReadyNAS 104 (firmware 6.10.10) with a 4-bay X-RAID2 setup: two Seagate IronWolf 4TB drives and two WD Red 3TB drives. The 3TB baseline across all four disks forms a RAID5 volume...

Thank you again for the detailed steps. No luck yet, I don't have a Windows machine on hand, so it'll take me a bit of time to procure one before I can attempt anything. Didn't want to leave your check-in unanswered, just may be a while before I'm back with results.
One clarification I'd like to have ready for when I do get to it: should the mount /dev/md127 /data command include -o ro (read-only) on this first attempt, given the two non-fresh disks (sdc3/sdd3)? Want to make sure I can copy everything off before anything writes back to the array.
Thanks again for your patience and help.

One update since my last message: I checked System > Volumes directly, and both data-0 and data are showing a red/inactive status with Free Space: 0, not just data-0. That, plus not having heard back on my earlier question yet, given the two non-fresh disks (sdc3/sdd3), I'm planning to include -o ro on the final mount /dev/md127 /data command on this first attempt, to make sure I can copy everything off before anything writes back to the array. Let me know if there's a reason that's not advisable for this specific case.

Yes, that is reasonable. You can also reboot the NAS read-only after the volume is mounted.
