Defragmentation of Harddisk
Technology Updates
Defragmenting
Everyone knows that regularly scheduled hard drive defragmentations are a good thing -- like puppy dogs and kittens. For the most part, however, the majority of the understanding ends right then and there. SearchWindowsManageability.com's resident defrag tool expert, Frank Alperstaedt, finds himself answering the same basic questions over and over again. In an attempt to help our users grasp some of the more fundamental concepts of defragmentation, this article features a package of recently and frequently asked user questions. -- David Pye
IT pro: What is defragmenting? Why should I do it? How do I do it?
Alperstaedt: Defragmentation is a process that rearranges and reassembles your files on your hard disk. Think of your hard disk as a shoebox where you store lots of notes (the files). Windows XP/2000/NT simply takes your note (file), tears it into pieces and throws it into the box. When you load that file again, XP/2000/NT must first search for each piece and paste them together before the file is finally loaded. That process is time-consuming and reduces your performance.
You can only solve this problem by using a disk defragmenter.
The purpose of defragmentation is higher performance when accessing files. Due to the files' continuous storage, the operating system can find and read each file fragment faster than before. Especially on file servers or heavily accessed workstations, a performance gain of up to 100% can be reached. The regular usage of a defragger suppresses new fragmentation and helps you to work faster and more efficiently with Windows XP/2000/NT.
Things to take note
Remarks
• A volume must have at least 15% free space for defrag to completely and adequately defragment it. Defrag uses this space as a sorting area for file fragments. If a volume has less than 15% free space, defrag will only partially defragment it. To increase the free space on a volume, delete unneeded files or move them to another disk.
Some think otherwise
