Interesting. Didn't realize there was this option. Ran the Check Filesystem. Output below. Message "File system corruption detected." received with a Fix button active. Didn't press it bc I'm too new at this and know better.
Phase 1 - find and verify superblock...
Phase 2 - using internal log
- zero log...
ALERT: The filesystem has valuable metadata changes in a log which is being
ignored because the -n option was used. Expect spurious inconsistencies
which may be resolved by first mounting the filesystem to replay the log.
- scan filesystem freespace and inode maps...
