Btrfs Can't Read Superblock on External Disk Problem

I have added the btrfs tag to your topic.

I’m not a user of BTRFS personally, however, the error seems to indicate an issue with the file system; perhaps btrfs-check might be useful:

The presumption is that btrfs-check would need to be performed on an unmounted file system (much like using fsck on an ext4 file system); perhaps best initiated from a bootable Manjaro Installer USB. Please perform research as needed.


Some system context might be useful for those wishing to help. Please provide full system information using the following inxi command;

inxi --admin --verbosity=8 --filter --no-host --width

I’ve taken the liberty of leaving you the filtered command which obfuscates any personally identifiable information from the output. You might like to add this to your notes.

Regards.
