Rich,
How do I do a defrag? Is there a utility software I should be running?
Thanks
Paul
Click Start / All Programs / Accessories / System Tools / Disk Defragmenter
Highlight the system partition ( C: ) and click Defragment. It may take a while, so do it when you won't be using the computer for a while. If you have additional hard drive partitions, you can do those, as well; but they have to be done separately.
There also is an "Analyze" button you can click for Windows to tell you whether it thinks you need to defrag, but in my opinion it allows the drive to get too fragged before recommending defragmentation. Defragging once a month is usually sufficient and a good idea, regardless of what the Analyze button says.
Don't defrag a computer during an electrical storm or other time when power failures are likely unless the computer is on a battery backup or uninterruptable power supply. When defragging a laptop, do it while on AC power.
If you're maintaining a clone using Casper, I wouldn't bother defragging the clone until such time as it's pressed into service. If you need it some day, you can defrag it once you've swapped it into the computer.
What defragmentation does is puts fragmented files back together. In the course of working with files, they get fragmented. What this means in simple terms is that the clusters that comprise a file will no longer be contiguous, but rather will be scattered here and there on the hard drive. When the file is called, the hard drive has to pick up the pieces wherever they lie, and they are reassembled in memory. This reduces performance and increases hard drive wear.
Looking at it visually, if we have three contiguous files,
A,
B, and
C, they might look like this on the hard drive:
AAAABBBBCCCCCCC
But after working with them for a while, they may look like this:
AACBBCCACCBCCBA
The Disk Defragmenter puts all the pieces of each file back together again, which decreases loading time, increases performance, and reduces drive wear.
Of course, the defrag process itself causes some drive wear, so you don't want to overdo it. Once a month or when the "Analyze" button results in a recommendation to defrag is usually sufficient.
