I know how RAID work and prevent data lost from disks failures. I want to know is possible way/how easy to recover data from unfunctioned remaining RAID disks due to RAID controller failure or whole system failure. Can I even simply attach one of the RAID 1 disk to the desktop system and read as simple as USB disk? I know getting data from the other RAID types won’t be that simple but is there a way without building the whole RAID system again. Thanks.
The OP made clear it was a controller failure or entire system (I read hardware here) failure. Which does complicate things somewhat.
Yeah, if there’s a full system failure without any backups and no option to get the system operational again then I would land in clone the drives before trying to restore data from them.
