[net.micro.mac] HFS Disk checker

stew@endor.harvard.edu (Stew Rubenstein) (09/05/86)

Does anyone know of a program (commercial or otherwise) which checks
the bitmap, extent, and catalog files of an HFS disk for consistency?
Something that reports blocks marked as allocated but not assigned
to any file, blocks multiply allocated, etc?

Failing that, does anyone have any example code which reads these
files for any purpose?  The program ought not be hard to write...

The other day, I found out something was wrong when FEdit plus crashed
when trying to open a file (any file) from my hard disk.  Everything
seemed OK from the Finder, but I did a backup, reinit and restore
anyway.  Anyone have any tools at all for helping to cope with this
situation?
