Alas, although a physical drive does have a fixed *manufacturers*
serial-number (which is quite easily retrieved from within DOS), I have not
found/seen/read of a method to retrieve it from within Windows.
There is a method
- I do not recommend it - it relies on a level of technology that one
of my drives does not support
I do not know where I got the code, however I doubt that they will
mind it being re-posted ... if otherwise ... apologies
- I strongly recommend NOT using this stuff
- it is asking for support calls
- however it is worth *knowing* about

'Most hard disks sold in the last few years support SMART
(Self-Monitoring,

use
'this to return the hard disk physical serial number, NOT the volume

'will ONLY change if you replace the hard disk.

'To do this, use add a reference for Microsoft Scripting Runtime.
