What a volume serial number looks like in Windows A volume serial number is the XXXX-XXXX identifier Windows generates and assigns to a disk volume when it is formatted (each X is a hexadecimal digit, 0 to F). It is separate from the drive's physical hardware serial number. Normally there is no supported way to change it without reformatting the volume; Volume Serial Number Editor changes it directly.
