If we have a lot of data and save at hard disk, one of the problem is about fragmentation. Harddisk save a lot of data in big or small size also we sometime delete and add new files at harddisk, this can make data separate to multiply sector of harddisk. Because data will fill blank sector first and if the blank sector is not enough than it will continue write to other blank sector which is sometime not always continuation of the first sector.
Saving a data to a harddisk is using a logical and systematic way, this will make file become fragmented. If this way is happen for long time and done for a lot of data, then the computer will need more time to find and collaborate a file in a fragmented harddisk.
By default, Microsoft Windows XP already have a tools for defrag harddisk, From desktop : Start > Programs > Accessories > System Tools > Disk Defragmenter. This tool provide by Windows to gather the scattered file and than write again to adjacent cluster, after defragment finish, each file can be become a contiguous section again at a harddisk.
Using Windows XP default disk defragmenter is good to make our computer run faster, but I don't like the slow process of this tool, also I think the default disk defragmenter of Windows XP is not do maximal job. Better for search other good and fast defragment tools.
Doing defragmentation at harddisk will not only make working at harddisk become faster, but also it can make harddisk more longer to life, because when the file structure already arranged in regularity, then the disk will do less work to call a file, it doesn't have to take any part in several locations of disk (maybe at beginning until the end of sector).
There are so many defragment sofware that can be download from freeware until shareware. In this article I want to share about a fast and easy defragment software call JKDefrag, the latest version is 3.36. Download it from this link: http://kessels.nl/JkDefrag/index.html JKDefrag is very easy to use for everyone. No need to install the software just click to run. So we can put JKDefrag portable at our USB Flash Disk for bring to anywhere.
Once we run JKDefrag then the software will run everything by itself. JKDefrag will start to defrag all mounted harddrive at computer. If we have a harddisk with 3 partitions, JKDefrag will automatically defrag it all start from drive C: then D: then E:, also JKDefrag will do defrag job for USB drive that plug into the computer and known as a new drive. I really like it, so usually to defrag all partitions at my computer, I run JKDefrag at night before I sleep and let the software run itself.
We can run JKDefrag anytime we want, and also it will not make something bad to our harddisk if we suddenly have to stop the defragment process, only when we want to defrag again with JKDefrag start from windows explorer by double click JKDefrag, than it have to start from the very beginning of hard disk drive. But we can choose which drive to defrag by run JKDefrag from command prompt with additional option.
