Yep Microsoft is so obviously at fault here.  First of all they designed FAT
in the late 70s.  Shame on them for using a filesystem design similar to all
the other systems at the time.  Then to top it off they have the audacity to
try and repair it when the user boots the system with a drive attached which
is corrupted.

UNIX is such a better system.  Let's see what does it do in a similar
situation?  Well fsck notices the drive needs repair, finds all these file
fragments that are listed as allocated but not attached to any directory.
Gee it makes up names for them and puts them in the lost+found directory.

Gee seems like exactly the same thing to me.

The only real lessons to be learned here is.  If your drive has a problem
don't continue to use it without fixing the problem.  Don't use an OS that
caches data on removable drives (Windows doesn't MAC OS apparently does).
Don't use an OS that mounts a drive that hasn't been closed properly
(another MAC deficiency versus Windows).  Finally don't give your drive to
someone that doesn't know what they're talking about to have it fixed.

Now you know why you should NEVER use MS products and operating systems to 
recover corrupted MS filesystems.

Yup. Same problem as happens when Messy-Dog (MS DOS) does it.

FAT is fine for floppies and that's where it should have stayed.
