@jope @batteman @codewiz Uhm, never had good luck wie AFS/SFS/whatever... with FFS repair is sometimes quite easy, if you are brave enough to do it:
1) quick format the partition
2) run "Unformat" from like qbtools or similar
3) be done.
DiskSalv and other "repair" operations resulted in my issues, sometimes. Quick Format & unformat worked fairly well. Not always, but in >90% of the cases.
