I am trying to recover data from a NAS that fell off a the top of a PC tower. One drive "sounds" OK the other one probably has something physically wrong with it.
For the first drive I get the following when I try to mount it.
david@Office-ThinkPad-T520:~$ sudo mount /dev/sdb2 /mnt
mount: /mnt: unknown filesystem type 'linux_raid_member'.
david@Office-ThinkPad-T520:~$
How do I read the data from it? ANy help would be greatly appreciated since about 15years of photos have been backed up to the NAS. (I know I should have had a cloud backup to - but such is the benefit of hindsight :-(
The second drive makes clicking sounds. But I get this from sudo fdisk - l
though after 15 minutes it didn't complete.
david@Office-ThinkPad-T520:~$ sudo fdisk -l

Thanks Norbert sudo fdisk -l /dev/sdb gives me

sudo fdisk -l /dev/sdb
to the question.sdb2
is a raid member. Look at/proc/mdstat
to find the md devices and try to mount them ( e.g./dev/md0
). It would also help if you add the output ofcat /proc/mdstat
to your question.
