is defragmentation necessary?

Question

what is the use of de-fragmentation

what interval we to do de fragmentation

what will be the advantage

Answer 1

It's something like this... You have a large library with many books! Each day you have to write a project based on several books. After you do that you don't have time to put them back where you got them because another project comes in and so on. Day after day if you don't rearrange them it would become harder to search for what book you need so you have to rearange them :).

Answer 2

In different O/S , Disk Space allocation is done as per the Demands from the System . Also , there are deallocations of space in case some Applications etc no longer use some specific Disk Sectors .
In course of time , the Disk Spaces that are being used no longer remain contiguos . Something like :

11011 0000111 0011 00
00101001111000111111

If you consider 1 as used and 0 as unused or free , you can see that there are quite a few discontiguos space distribution .

DeFragmentation is the Process which makes more of Contiguos space Allocation . But it does not make 100% contiguos space. Some Fragmentation still remains . What interval ? needs to be decided upon :
1: How Heavy / How much Daily Usage your System is undergoing ?
2: What Special Tools do you have for DeFragmentation .
3: Do you need to take any of your Disk Drives or Disk Controllers Offline for doing Defragmentation .
4: In case of Commercial Usage , Cost for Doing such an Exercise ( Its the question of Money,Honey !!!! )

Hope this answers your question .

Answer 3

First thing's first: 'Fragmentation' is how we describe what happens when a given file (a program, an MP3, a word document, etc) gets it's bits and bytes stored on non-contiguous sectors on your hard drive, causing the drive to have to re-position the read head too often, slowing drive access and increasing the opportunities for error. 'De-fragmentation' shuffles those sectors around so that file's sectors are as contiguous as possible.

The advantage of defragmentation is that it restores your drive access speed. It won't make your drive access any faster than it was right after you installed your system, but it will take a system that has slowed over time and restore some of that 'fresh system' snappiness.

The interval between defrags is entirely dependent on how often you add, move, and delete files. If you are a download hound that pulls bunches of small files off the web on a regular basis, and moves them to other areas, or shuffles them around (decompress, extract, burn, whatever), you may want to defragment fairly often. If you mostly just surf the web and read your email online (via a web browser), it may be nearly unnecessary for your usage patterns. In the end, you should find out what your vendor (Microsoft, for most people) recommend, and follow their directions.

Answer 4

Reading and writing data on a heavily fragmented hard drive is slowed down as the time for the heads to move between fragments on the disk surface can be substantial. The disk operates at speeds millions of times slower than the CPU; thus the desire to process more efficiently encourages defragmentation. Operating system manufacturers often recommend periodic defragmentation in order to keep hard drive access as fast as possible.

Answer 5

Think of defragging as reorganizing your computer. Let's say you have a 30 volume encyclopedia at home. Ideally, you want all the volumes to stay together. But maybe volume 3 goes into the garage, volume 7 into the master bedroom, volume 12 into the kitchen, etc. All the volumes are in the same house but they're scattered. You can find them, it'll just take you some time.

Same thing happens to the files on your hard drive. They get scattered through use. The more scattered, the longer it takes to find things. Defragging attempts to take all those scattered files and physically move them closer together. So searches go faster.

Answer 6

Defragment moves your files together. When you delete files, it makes gaps on your hard drive. When your computer runs a program, it has to look for files in different areas of your hard drive. The gaps make it run slower. When you defragment, the files are moved together - no gaps. Its like if you had to go to New York for a file and Miami, and then Los Angeles. Just keep them all in Miami and you don't have to run all over the place. Your computer will tell you if your hard drive needs defragmenting - just let it analyze. When a certain percentage of files are fragmented, it will tell you to run the defrag. You sound as though you have never done it to your computer; in that case, defrag now.

Answer 7

Its not neccessary.....but its essential.It can help you to use your hard dsik more effieceintly by arranging the data in an oder.When we add or delete sumthing on our computers , the data is stored nt in a proper order,Whn we defragments a drive, it arranges it well and makes our work go faster.

Sumtimes it also lets u know how bad or good ur condition of hard disk is.

Answer 8

yes it makes you computer faster.it gets rid of fragmented files.etc.depending on how much you search the net is to how often to do it.i suggest once a week

Answer 9

It most absolutely is necessary

Answer 10

yes it can save the amount of free space on your desk top
