There are better defragmenters than the one that comes with the system, and really it's not necessary to defrag unless you are beginning to notice a slowdown in system responsiveness, or if you have just installed or uninstalled a program that takes up a significant percentage of your HDD space.
Brink, thanks for this guide but I want to ask you something.
On Screen one, we can see a third disk named as Volume{....
I have a disk like this but my friend is not. What is this disk could you tell me please?
In forums, I asked this and some peoples said that it was System Reserved disk. Is it right?
It was the System Reserved partition as it was listed in one of the earlier prerelease Windows 7 builds. It shows at System Reserverd now in all retail versions of Windows 7 now though.
Thank you John. Luckily Windows 7 usually will be set to not run Disk Defragmenter by default on the latest SSDs out there. It's still worth to check and make sure though.
