Hard drive serial number

[daslick]

Hard drives have a serial number that never changes even after formatting and they also have a volume serial number.

I am considering using the MAC addresses of all the network adapters and the serial numbers of the hard drives as returned by DriveGetSerial. Is anyone sure that this is NOT the volume serial number? At this point I am going to require that 2/3rds of the MAC Addresses and hd serial numbers. Any other suggestions?

Looks great! None of that data will change if the user formats?

Depending on version 1 or 2 there are several different criteria. You'll have to sort out, which don't change on format but e.g. on hardware change only:)...

Guess something like

$objItem.Architecture

$objItem.Family

$objItem.L2CacheSize

$objItem.L2CacheSpeed

$objItem.Manufacturer

$objItem.MaxClockSpeed

$objItem.PNPDeviceID

$objItem.ProcessorId

shouldn't change on format.

If you browse the thread you'll also see same alternate methods which may suite your purpose better.

Ok great. I'll probably test it on myself with a format... Thanks!
