I believe you are recommended to defrag your computer at least once a year but to be safe i usually run one every 2 months or so. I personally recommend you use a program called defraggler which does a good job at defragging.

Disc defrag won't finish on windows xp?

The very best way to run defrag is to startup your PC in Safe Mode and then run the defrag. Safe Mode is available by rebooting your PC and start tapping your F8 key (I tap it about once a second) until a menu comes up asking how you want to startup. Select the Safe Mode option and enter. ... if you're in the normal mode close all applications that are running then defrag but still the best way is "to run defrag is to startup your PC in Safe Mode..."


Can you defrag your hard drives while still using your PC?

With Windows XP if any programs (even those running in the background) or the screensaver interrupts the defrag, it will restart/hang. In Vista, the defrag is designed to defrag at a certain schedule in low priorty in the background. In order to defrag and use the PC at the same time you need to use an automatic defragmenter like Diskeeper which runs in the background in invisitasking mode and defrags silently without conflicting with other programs.

Do you have to be on the Internet to defrag?

No! In fact, it's best that you're NOT online while doing a defrag. Anytime defrag hits a part of a hard drive where the information is changing, defrag restarts doing that portion of the drive. While on the Internet, your PC is constantly sending and receiving files and changing what's on the hard drive. Your defrag will take a lot longer.

How do you run defrag with vista?

As far as I am aware, in Vista, you can't select specific drives to defrag. It's all or nothing. Do note that Vista uses a type of automatic defrag. That said, the automatic defrag in Vista is not as good as some of the third party solutions. The commercial defragmenters offer more control and features than the Vista defragger. Generally, automatic defrag is better than older manual or scheduled defragging since defragging takes place in the background without user intervention. Files are maintained in an optimal condition while the user can continue to work on the PC as usual.
