4-1-5 Defragmentation

Files created on this system are managed by Windows.
When a file is updated, Windows may write the
changed section of the file to a sector on the hard disk
drive that is different from the sector where it was
originally stored. If the file is updated repeatedly,
different sections of the file may be distributed to
widely separated locations on the hard disk drive.
Reading from and writing to such files takes much
time, possibly causing skipping during playback of
video and audio signals.
To prevent this from occurring, you should
periodically use the standard Windows disk
defragmenting tool or another defragmenting tool to
defragment the hard disk drives.
Refer to the Windows Online Help for more information
about using the Windows defragmenting tool.
Refer to the documentation supplied with the tools for more
information about using other defragmenting tools.
Note
Defragmenting tools require a certain amount of free
disk space to operate. Before defragmenting a logical
drive, check to be sure that the drive has at least 20%
free capacity.
