Hello,
I have worked with RAID setups for a long time (both hardware and software).
I have managed to recover data from NAS devices (such as WD sharespace), HP servers with hardware RAID controllers, regular machines with software RAID (level 5, 10).
Can you give me some details about this NAS device? If you can provide me with access to that device I can take a look at the situation.
Thank you for your time!
Best wishes,
Ionut
