I am looking for the following parameters:
- RAID type (XRAID, RAID4, RAID5, etc)
- Block order
- Parity delay
- Block size
- etc...
dmesg.log says its RAID-4, and will tell you which drive is the parity disk - normally disk 3 (numbering from 0).

There might be some more info scattered around, but I'm not seeing what you're looking for.
Is your array (and NAS) functioning? Are you attempting to mount in a linux system? Or something else?
Thanks for you prompt reply!

My NAS was stuck on booting (see this thread). I put in four (4) new discs and the NAS itself is functioning fine again now.
Unfortunately, up till now, I am unable to recover any data from my four old discs through R-Studio, ReClaiMe, etc. probably
because I do not have the right RAID parameters. My idea is to find the parameters from the current log files in the NAS with
the new HDDs and put those parameters in, for instance, R-Studio.

It's a bad sign that R-Studio and ReclaiMe aren't able to detect the RAID parameters. Have you tried this: https://www.r-studio.com/Unformat_Help/finding_raid_parameters.html
JohnCM_S and/or Marc_V should be able to track down what you need though. If they don't respond, I suspect R-Studio and ReclaiMe support both know this parameters, so they should be able to help.
