The ICN# is usually stored in the driver itself.  The hex replacement that
you describe will work, but you need the mask too to make it look nice.

HOWEVER:  You run the risk of twiddling the wrong byte in the driver and
making it useless.

I played a part in developing a driver/partitioner package.  We included
a facility for the user to develop his own icon and change it on-the-fly
while running the partitioner utility.  The software is currently being
shipped with some Everex drives, but due to their specification, the
user interface is nothing to write home about.  The driver is well written
and has password protection and encryption built in.
