If you want two more identical drives then use dump, not tar, but you'd 
have to have them sliced/partitioned up the same beforehand and it 
wouldn't do bootblocks.

Silly question, but won't your RAID controller do it for you?  Or is 
that expecting too much?

Or what about using Ghost?  No experience of *doing* it myself, but 
someone I work with did it very successfully just a couple days ago to 
get a copy of an unbootable <hawk, spit> Linux SCSI disk onto an IDE.  
That would make the disks identical.
