How to unique identify a PC by it's hardware information?

NTDEV
1

Hi,
I want to unique identify a PC by it’s hardware information. Now I use Hard drive disk serial number.
But there is some question: I Just can get the IDE HardDriver’s serial number can’t get SCSI HardDriver’s serial number. How I get SCSI harddriver’s serial number?
Is there another way to unique identify a PC by it’s hardware information but without use it’s HardDDriver’s Serial number?

Thanks for you help .

MAC address on the network card.

I’ve seen too many systems that all had the same disk serial number, usually
zero.

Hi,Loren Wilton

Thanks for you idea. But many computer doesn’t have any Network Adapter!

We tried this approach and had problem with some wireless network cards
(sony lap tops, etc). The MAC address changes each time the machine
reboots.

I supose you can’t just use the SID the OS generates for the machine
during installation?

The problem with using hardware information is that people change
hardware. Particularly using the ID of something like an IDE hard drive
(which I pretty much have to replace every year in my home machine)
seems bad. What about a different piece of hardware like the NIC?

Also, we ran into many computers with the same MAC address, even
counting machines only with actual landline Ethernet cards. Apparently a
few manufacturers were not very careful in the past.

For what? any such numbering can be faked very simply.

Now I use Hard drive disk serial number.

Ethernet MAC address is simpler.

But there is some question: I Just can get the IDE
HardDriver’s serial number can’t get SCSI HardDriver’s serial
number. How I get SCSI harddriver’s serial number?

At least the ancient SCSI-2 spec does not specify this in any mode
pages or INQUIRY data.
Dunno about the more modern versions.

Usually, the disk replace requires the OS reinstall, which will also
generate a different SID.

Hi,Peter Wieland

That’s a good idea. But sometimes, we get the some system that copied by Ghost or the same kind software , then all there system have same SID.
