remove inactive disk and possibly a bad disk
Good day, I have a messy issue with a lot of uncertainty and forgotten facts because this happened over a year ago and I'm now trying to recover my data. I have a ReadyNAS, RNDU4000. Firmware 6.10.5...

My question is - What is the best way to restore the data? I don't need to get the system running again. Just want a backup of all files I had. I think the disks were setup as RAID 5.
Or is it a lost battle?
I think the best path is data recovery.
If you want to try that on your own, you'd need a way to connect the disks to a Windows PC and try ReclaiMe software
( https://www.reclaime.com/ ) or other RAID recovery software that supports BTRFS.
Netgear also offers a data recovery service you might be able to use: https://kb.netgear.com/69/ReadyNAS-Data-Recovery-Diagnostics-Scope-of-Service One issue with this is that you have a legacy NAS running OS-6 which they normally won't support. They might make an exception for data recovery - not sure.
There are other folks who offer this (some might be local to you). Best to check whether they have experience with mdadm raid + btrfs before you contract with them - many folks are more experienced with PC/Mac data recovery.
After you get the data back (being positive!) - you should put a backup plan in place. Devices can fail, and RAID isn't enough to keep your data safe.
I've been trying to reach the support for a few weeks without success. So my best options seams to be to do it myself.
A question to your suggestion

Are there any tool that can recover directly from the NAS thought the network, so I don't have to connect the disks individually to my computer. I only have one SATA/USB connector available at the moment and I guess would be good to let the recovery program have access to all 3 drives when it's doing its magic.... just guessing though.
Many thanks

You'd need to get suitable adapter/docks, so you can connect all three drives. There are some that handle multiple drives. Prices vary, but you can find 4 bay enclosures for about $125 USD.
