Disk fragmentation degrades hard disk performance over time.
When files are not stored contiguously on the disk, the
read/write head has to reposition itself frequently, and this
takes time. Thus periodically defragmenting your hard disks is a
good idea, and Windows comes with a utility to do this called
Defragmenter.  Defragmenting a hard disk takes some time, so
it's not something you'd want to do unnecessarily. However, the
version of Defragmenter that comes with Microsoft Windows 98
does not report whether your hard disk needs defragmenting, and
the Windows 95 version of Defragmenter has very limited
reporting. When you select one drive, the Windows 95
Defragmenter will report a fragmentation percentage if the drive
does not need defragmenting. But if you select multiple drives,
the process will start immediately without a report. In
addition, the calculation method of the Windows 95 version of
Defragmenter is faulty. It often reports that a drive is not
fragmented when the drive really is.  CrackUp, whic
