Are you sure? I read that as group disk having read *and* write access.

Obviously the OP seems unworried about read-access by himself or
anyone else, so world-readable on pretty much everything might
be appropriate.

Reading anything about a filesystem without going through the
normal access methods would appear to circumvent any file
protection scheme within it, so it's no surprise to me that
all the suggestions with lsblk etc have failed.

Cheers,
