windows - How to get hard drive serial number from command line?

From the Windows NT-based (Windows XP and 7 specifically) command prompt, how can I get the serial number of a hard drive as a variable? The one I'm looking at is the serial number of the physical hard disk drive

Answer

Try this command

this will get the volume serial number given to it by windows.

wmic diskdrive get serialnumber

this gets the manufacturers serial number of the hard drive.
