Volume Serial Number Editor allows you to modify your disk drive's volume serial number (not hard disk's physical serial number which you can find at back of your hard disk) without reformatting your hard drive.

This disk serial number is automatically generated and assigned when you format a disk partition and there is no documented way to change it without reformatting the disk volume. The format of volume serial number is: XXXX-XXXX (X maybe 0, 1, 2, 3, 4, 5, 6, 7, 8, 9, A, B, C, D, E, F). Volume Serial Number is a serial number assigned by the Operating System to a disk volume.
