Ah, right - so you're trying to avoid replacing a disk when SMART tells 
you it's starting to fail?  I can see where this might be handy in a 
massive ultra-low-cost storage (hey, come get 5GB of free e-mail 
storage) farm but I wouldn't recommend it for a typical business 
client.  Sort of like the badmem patches for linux - a cool hack but 
maybe not the wisest idea.

Lately I've just been seeing disks fail cold - no warning, just pop an 
IC - no motor, no heads.  Especially Hitachi Deskstars [cue Vader 
voice], 250GB range.
