I have a question on this.  Is it even possible?  I don't know the 
details, but I seem to remember that each controller writes to the disk 
in its own way so that another controller type (different brand of SCSI 
controller) won't be able to read the disk or use it.  Anyone remember 
what I am talking about?   I don't remember details -- this is from a 
while ago that I have this memory...  (Seem to remember that, for 
example, swapping out a symbios logic for an adaptec wouldn't work since 
the low level controller stuff was not compatible)

best
Chad
