[I modified the question to reflect the progress]
The TLDR version is, the card is adopted storage that says corrupted f2fs.
I used the process detailed Here but when I tried to mount the decrypted SD Card
I got "system call failed: Structure needs cleaning".
#mount -t f2fs /dev/mapper/crypt1 /mnt/1/
mount: /mnt/1: mount(2) system call failed: Structure needs cleaning.
When I tried to use fsck, I got "Error: In use by the system!"
#fsck.f2fs /dev/sdc2
Error: In use by the system!
Below is the info that may help you help me.
I'm not a linux expert, is this something I can correct?
After fsck.f2fs /dev/mapper/crypt1; mount -t f2fs -o ro,norecovery /dev/mapper/crypt1 /mnt/1;
I get:
many more like this
I'm not sure what to do next; if I restore is the lost directory on the corrupted drive or the main drive?
mount: /mnt/1: can't read superblock on /dev/mapper/crypt1.– Captain-Science Feb 09 '23 at 18:40
