You could create you own specially named file with ascii value > 128
and then store your own "Serial Numbers" in it, to keep prying
eyes out set the system and hidden bits.  
This is probably the easyest solution.

IDE drives have unique serial numbers burned into the ROM which can be
read by software (I posted a link to one source listing earlier in this
thread).

In the case of security and tracking systems, Volume serial numbers
aren't secure.  It's easily modified with a sector editor, and source is
readily available to modify it without a sector editor.  When you have
multiple partitions, each partition has its own volume number, which
repartitioning will also blow away.

How is this done?  I've heard talk of this, and since it's usually
displayed on the screen at boot-up, there should be some way to
accomplish it.  Any pointers, URLs, etc., that might provide some leads
on this?

Hi Louis,

just a couple of weeks ago we had this discussion after just the
same question of mine and some people were kind enough to explain
it.
I've tested it in PM and RM and it works fine. If you're interested
I'll email you the source code.

The only way I know of to get a harddrive Serial number is to take the
harddrive out of the computer and looking at the number on the label.

Why couldn't you use the volume serial number?  There is a program out
called VASN that allows you to set a volume label's serial number to any
hex digit you which (if you are worried about the harddrive being
reformatted (how often would anyone expect that to happen?)).

A better suggestion (probably the best) is to not use a harddrive's
serial number, but instead use the BIOS serial number which is on the
motherboard, and can be read on nearly all computers.
