While Windows NT/2000 and Windows 95 and 98's 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).
Usage: volumeid <driveletter:> xxxx-xxxx
This is a command-line program that you must run from a command-prompt
window.
Note that changes on NTFS volumes won't 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.
This module explores file system fragmentation and the tools that you can use to reduce fragmentation. Students will learn how Windows can compress files to take up less space on the hard disk.
