This is a _very_ bad idea 

1.  MSDOS allocation chains are _not_ preserved when a file 
    is deleted.  

2.  Unlike unix, MSDOS stores the metadata in a directory.  If that
    directory is corrupted, you loose the metadata for the file.

3.  The MSDOS filesystem is inherently fragile compared with 
    a unix filesystem.

If you want *real* protection, mount things read-only where 
possible, use a backup system, store backups off site, use a 
UPS, and mirror your disks.

There's an undelete for Linux, although you loose some meta-data and 
may loose everything referenced in the indirect blocks.
