Abstract

The workstation user experiences gradual degradation of a machine's performance due to increasing disk fragmentation. As new files of various sizes are stored on the disk, and old files are removed, over time, the disk becomes quite fragmented. This degrades performance through increased I/O activity, because the system has to write new files in several scattered segments. Furthermore, the user often doesn't realize the gradual degradation in performance, so the problem goes unchecked until it becomes quite serious. The user needs a way of automatically checking the fragmentation on each partition, without leaving the desktop. Then the user would be able to constantly monitor the disk, and gauge when a disk optimization utility should be run.

Graphical Disk Drive Fragmentation Control

      The workstation user experiences gradual degradation of a
machine's performance due to increasing disk fragmentation.  As new
files of various sizes are stored on the disk, and old files are
removed, over time, the disk becomes quite fragmented.  This degrades
performance through increased I/O activity, because the system has to
write new files in several scattered segments.  Furthermore, the user
often doesn't realize the gradual degradation in performance, so the
problem goes unchecked until it becomes quite serious.  The user
needs a way of automatically checking the fragmentation on each
partition, without leaving the desktop.  Then the user would be able
to constantly monitor the disk, and gauge when a disk optimization
utility should be run.

      This system adds a new graphical End User Interface (EUI)
control called the Disk Fragmentation Indicator (DFI), which surfaces
disk fragmentation so that the user is aware upon detection of such
fragmentation.  At user-configured time intervals, this system
queries each partition as requested by the user-configured profile.
It surfaces a fragmentation indicator by partition, in bar chart
format, if there is excessive fragmentation detected.  Optionally,
the user can configure to surface the bar chart indiscriminately.
The fragmentation measurement, which is also a part of this system,
is defined and calculated as follows:
