Defragging is [url=http://www.sandvikfw.net/shopuk.php]hollister sale[/url] method performed on a hard disk so that you can improve performance and recover some lost disk space. Defragging is [url=http://www.thehygienerevolution.com/hollister.php]hollister france[/url] a vital part of a PC's upkeep as it keeps all the data on your harddrive in an easily readable order. If a disk drive is left without defragging, then as time passes the disk will begin to lose performance and also slowly reduce the available capacity to data. As you will be aware if your hard drive is running slowly then this will affect the rest of the system performance, in all applications and especially in games, where frame rate is important.

When you defrag your drive you re-arrange the order in which the data is stored on the drive. The Pc will arrange the data so that data that belongs together and needs to be read together is actually put in the same place on the drive. The obvious question here is why doesn't the PC store the data in the right way in the first place? In an ideal situation (such as a blank disk) the PC would [url=http://www.gotprintsigns.com/abercrombiepascher/‎]abercrombie pas cher[/url] do these as a first option. However with the amount of data being deleted and wrote to the disk every second the Computer is on it is no [url=http://www.giuseppezanottipaschere.com]giuseppe zanotti sneakers[/url] wonder that the data cannot be stored together.

Lets have a look at an example. Say you write 3 files to a disk all 10Mb in size the data would be all in a line each 10mb block after the [url=http://www.fibmilano.it]woolrich outlet[/url] other. This is how your PC would [url=http://www.ktbruce.co.uk/barbourjackets.php]barbour jackets[/url] prefer to store the data for maximum performance. It stands to reason that this is how you would like it to be stored as well if you needed to search for the data. But now lets say that you decide to delete the middle file as its no longer any use to you. You now have a gap inbetween your files.

Lets say this time you write a file of 15mb in size. This file will be written in the first 10Mb of space and the remaining 5Mb added to the backend of the free space.As you can imagine with the millions [url=http://www.rtnagel.com/louboutin.php]louboutin pas cher[/url] of files being written to and deleted from the disk each day, [url=http://www.agentparadise.com]woolrich outlet[/url] not to mention the temporary files that windows uses on a frequent basis its not hard to imagine the state in which your hard disk can be in after months of use. After a defrag in this simple example your PC would re-arrange the disk to look as follows.

When files or indeed groups of files that belong together are stores next to each other the PC has a much easier time locating the data plus the disk heads don't have to travel to different parts of the disk to retrieve the data required. This of course speeds up the disks performance and so in turn increases overall system performance. There are of course levels of performance gains. It [url=http://www.gotprintsigns.com/abercrombiepascher/‎]abercrombie soldes[/url] becomes more negligible as you move to faster hard disks with large memory buffers to compensate for file fragmentation however I would not ignore the problem of fragmentation, it doesn't take much effort to defrag your disk now and then

Simply put defragging doesn't really create any free space on your hard disk. It may appear when you look at the graphics that defrag programs show you, that the disk looks like it has more space, but all you are doing is moving data [url=http://www.davidhabchy.com]barbour sale[/url] about not removing any. Any disk space gain is negligible and is caused when the defrag program puts together half clusters of data. If a file is broken into pieces around the disk and defrag can put the file back into a single cluster, or just save a cluster somewhere a small amount of space will be released.

Programs such as Norton Speed Disk can also sort your entire sets of files and programs into the order that they are used. You will be pleased to know that Windows comes with an adequate defrag program which everyone can [url=http://www.ktbruce.co.uk/barbourjackets.php]barbour.co.uk[/url] use. There are also some other pieces of software out there for a more specific use. [url=http://www.rtnagel.com/airjordan.php]jordan pas cher[/url] Norton Speed disk is one option on the market which comes as part of Norton Utilities and Norton Systemworks.
