Well, the Disk-Validator that lives in the L: directory does not really
fix the file structure.  Its main function is to rebuild the bit map so
that AmigaDos knows which blocks are free to be allocated to new files.
It gets invoked when the bit map has been altered but not yet written to the
disk when your Amiga crashes or loses power.  (It is also invoked when the
floppy is so full that there is no room to write out the bit map.)

C:DiskDoctor has to be invoked manually, and I'm not very impressed with
its success rate.  Release 1.4 could use improvements on this account.
