This should not be confused with the hardware serial number that gets added in the manufacturing process. The Hard Disk Serial Number Changer (link) can change the serial number that gets assigned when a hard drive is formatted in Windows. This can be really useful if an existing hard drive has to be formatted without loosing an activation or software association. It can also come in handy if a new hard drive is added to a computer system to replace an older one especially if software needs to be transferred or reinstalled on that new hard drive.

The software program is portable and can therefor be executed directly after finishing the download. The program will provide access to all drive letters of connected hard drives and floppy drives and their assigned serial numbers.

A click in the Serial Number text field allows to edit the existing serial which has to be in the form XXXX-XXXX with only hex symbols allowed.
