Disk Defragmenter in Windows 7 Takes a Long Time


This tip will help Windows 7 users and possibly also users of more

recent versions. If you disable your wireless Internet access network, defragmenting

will take much less time. Many computers have a wireless disable key,

often one of the function keys.


For wired networks, never disconnect the  ethernet cable.

Instead turn off the computer, then the wired router or modem. Then run

the computer with the modem or router off. When done defragmenting,

turn the computer off, then turn the modem or router on. After its ready

lights are on, you may turn your computer back on.


Some Internet Security or antivirus programs may run Disk Defragmenter

frequently as a default setting. If it is run in this manner, it will probably

pick up where it left off if the computer was not on long enough.


Always precede manual Disk Defragmenter runs with the Checkdisk

utility and the Disk Cleanup utility first.

The Checkdisk utility is accessed by right-clicking drive C in the files and

folders utility (Windows Explorer). Select Properties, Tools, Error Checking.

I recommend checking Automatically Fix File System Errors but not Attempt

Recovery of Bad Sectors. That is because the latter is normally not necessary

and can take hours to run.


The Checkdisk utility will only run at the next startup of the computer with these

settings. You will see a message asking you to approve this when you set up a Checkdisk



Running these 3 utilities monthly will help keep your Windows computer from running too

slowly. Checkdisk and Disk Cleanup could take 20 minutes each to run. Disk Defragmenter

could take up to an hour or two depending on how much is on your hard disk.
