that could be detected and fixed..

the last time I copied a disk exectly I was puting it on a differnet
machine..
it only has to be unique for that machine.
the network considers the machine as part of the device ID.
If you have it on the same machine you probably are replacing a suspect
drive in which case you are doing the right thing,
if you want both drives on at once, just add 1 to one of them.
(and write it back).
