I've never put grub on anything other than sda.  I do know that grub has 
some areas on the disk that it needs to access outside of a file system. 
  Fedora uses some security modules like selinux.  I don't know if that 
is the issue or not.

The way I'd do it is to just replace the disk so it is recognized as 
sda, boot with a rescue CD, make sure that /boot is mounted correctly 
and then run 'grub-install /dev/sda'.
