While WinNT/2K and Windows 9xs built-in Label utility lets you change the labels of disk volumes, it does not provide any means for changing volume ids.
This utility, VolumeID, allows you to change the ids of FAT and NTFS disks (floppies or hard drives) on both Windows 9x and Windows NT/2K/XP/2K3.
VolumeID lets you change the ID of your HDD using the command : volumeid xxxx-xxxx, where X: is the letter of your drive and xxx-xxx the NEW ID.
Note that changes on NTFS volumes wont be visible until the next reboot.
In addition, you should shut down any applications you have running before changing a volume id. NT may become confused and think that the media (disk) has changed after a FAT volume id has changed and pop up messages indicating that you should reinsert the original disk (!). It may then fail the disk requests of applications using those drives.
