The partitioning scheme...
The computer technician who usually cares for this company believes that the system was in RAID 1.
the manual suggests that the maximal RAID 1 storage capacity for this system is 2 TB...
Should I assume a RAID 5 system and try reassembling the third partition of drives #1 and #2 with the unique partition of drives #3 and #4 ?

WD Sentinels can work in RAID1 mode only if it's a two-drive model or if there are only two drives inserted.

The manual suggests that the DX4000 can also work in RAID 1, but with a maximal storage capacity of 2 TB.
I don't know if in such case drives #3 and #4 are ignored or if the mirroring is done on as many drives are present in the NAS.
Yes, I also assume the system is using RAID 5.
RAID Reconstructor from Runtime is an alternative to UFS Explorer to reconstruct RAID 0 or RAID 5 : http://www.runtime.org/raid.htm

I totally agree. However, the documentation helps looking in the right direction. The manual only mentions RAID 1 and RAID 5. So, useless to search for RAID 10 (1+0). If the system supported it, it would be mentioned as it would be a sales argument.You might want to look more at the hex rather than the manuals
Absolutely. The last screenshot in my second post shows they are not mirrored.You should be able to tell if the drives are mirrored by comparing hex values at different parts of each drive (especially drives 3 and 4).
Totally agree. Yes it's RAID 5.If the drives do not match then its most likely RAID 5. If two sets of drives match, then its a RAID 1.
With 4 x 2TB drives, RAID 10 (1+0) would allow a maximum storage of 4 TB, not 5.5 TB.Indeed, I didn't see the last post. A 5.5TB partition. I also meant 1+0 rather than RAID 1
Raid5, Backward dynamic, 64Kb stripe size.
In sector 3907023920 of each drive should be present interesting info about this raid5 layout (Order, stripe size, offsets and so on)

Outside the fact that the 64 Kb stripe size is widespread, how do you know that this RAID 5 uses 64 Kb stripes and that it is "Backward dynamic"?
Did you ever work on this NAS model ?

I need to recover the data, I already have the 4 drives connected to USB ports on a laptop, but i need to recover the data, what software did you use SOSdonnees , can you please help me out here.
Thanks

Fixing the Boot issue is a headache, you will waste alot of time repairing this Storage (took me few days to get it back online)
i suggest to recover your files to another NAS (recommend Synology)
good luck

The solution is very clear here (If you a real DR Company),
but IF not am sure there are MANY DR companies ready to Assist in your country (Paid of course).
