Noone knows. The GUID is not random that is for sure. But it is somehow related to the hardware in the machine, possibly to the ip address, the time of day, and god knows what else... You can try asking MS but it is highly likely they will not tell you because that would be a massive security flaw in windows... > Or how (if it is random) LDM driver knows that new inserted > drive contains part of Volume. Each dynamic disk contains the COMPLETE LDM database. Therefore each disk describes all the other disks. Also, IIRC, each disk stores its own GUID so the LDM driver can tell them apart.
