Defragging is method performed on [url=http://www.lotogame.fr/louboutin-pas-cher/]louboutin[/url] a hard disk in order to improve [url=http://www.corsodiesperanto.it/hoganit.html]hogan outlet[/url] performance and recover some lost disk space. Defragging is a vital element of a PC's upkeep as it keeps all the data on your hard disk in an easily readable order. If a hard disk 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 disk drive is running slowly then this will affect the rest of the system performance, in all applications and particularly in games, where frame rate is important.

When you defrag your harddrive 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 do these as a first option. Though with the amount of data being deleted and wrote to the disk every second the Pc is on it is no wonder that the data cannot be stored together.

Lets take a look at an example. Say you write 3 files to a disk all 10Mb [url=http://www.riad-marrakesh.fr]abercrombie pas cher[/url] in size the data would be all in a line each 10mb block after the other. This is how your PC would 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 [url=http://www.corsodiesperanto.it/moncleroutlet/]moncler outlet[/url] 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 of files being written to and deleted from the disk each day, not to mention the temporary files that windows uses on a frequent basis its not hard to imagine the state in [url=http://www.dearilievi.it]piumini moncler outlet[/url] 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 [url=http://www.davidhabchy.com]barbour outlet[/url] in turn increases overall system performance. There are of course levels of performance gains. It 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 [url=http://www.diecastlinks.co.uk]hollister uk[/url] much effort to defrag your disk now and then

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 about not removing any. Any disk space gain is negligible and is caused when the defrag program puts together [url=http://www.skoda-witzke.de/woolrichoutlet.php]woolrich outlet[/url] half clusters of data. Clusters can hold a number of files, but if not filled the next file is started at the next cluster. If a file is broken into pieces around the disk and defrag can put the [url=http://www.par5club.com/louboutin.php]louboutin[/url] file back into [url=http://www.jeremyparendt.com/Barbour-Paris.php]barbour pas cher soldes[/url] 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. For example it can be set so that your windows [url=http://www.jeremyparendt.com/Barbour-Paris.php]barbour france paris[/url] swap file is at the fastest part of the disk, followed by games and most used applications which also need the fastest part of the hard disk., Then documents etc and rarely used application can be put to the back of the disk., This gives the priority speed access to the applications that need it most. [url=http://www.mxitcms.com/abercrombie/]abercrombie[/url] Again this may only be a small increase in performance but every little helps. You will be pleased to know that Windows comes with an adequate defrag program which everyone can use. There are also some other pieces of software out there for a more specific use. Norton Speed disk is one option on the market which comes as part of Norton Utilities and Norton Systemworks. Doing a search on Defrag software on your favourite search engine will give you some options of free to use and pay for software.
