That _can_ be due to internal fs corruption, but it's most often due
to hardware bad sector errors.  It's the standard filesystem error
code returned when the fs notices something bad on disk, whether
that's a failed IO or a data inconsistency.

Did you try "dmesg" to list the full kernel console log?  There are
console settings which limit the echoing of kernel errors to the
console, but "dmesg" will the entire recent kernel log in one go.
