Okay.
D has 0 fragments.
C has this:
Diskeeper has completed a defragmentation run on this volume and there remain 149 fragmented files and/or directories and 458 excess fragments. (There were 8176 excess fragments before the defragmentation run, and now there are 94% less.)
The average number of fragments per file is 1.00.
On average, you have 0% excess fragments per file on this volume. This is a slightly fragmented volume. You should schedule Diskeeper to run at least once a day (if you haven't already done so) to keep fragmentation at a low level.
OK let's get to work.
Put the install CD in the CD drive.
