Definately. The 3ware daemon does this when it detects the drive did a 
relocation (I guess it does it via SMART) and I definately like the way 
this is done.

As far as I can understand, the 3ware hw raid5 will kick any drive that 
has read errors on it though, but I am not 100% sure of this, this is just 
my guess from experience with it. I have successfully re-introduced a 
failed drive into the raid though, so I guess it'll relocate just the way 
we discussed, when it actually tries to write again to the bad sector.
