Why should I use Disk Defragmente.?

Answer 1

Because you don't have a Macintosh?
If you had a Mac, you wouldn't need to defrag, since the OS does it on the fly. It also doesn't have a registry to get bloated or corrupted. :)

Answer 2

Disk defragmenter takes the information on your disk/ HD and compiles it hopefully in order
Background Info: Whenever anything is put on your comp. it is put on the first "empty" space on the drive then it jumps to the next open space and continues putting the information there, now the problem with that is now your information/program is in several fragments throughout the drive and in order to access the program/file the comp. must go back and forth jumping around the drive to find and get it all, which obviously takes time, and can cause a crash in slower systems. It is always a very good idea to defrag before installing a new program or game and after the install is done to try and keep all the files and bytes together.
Also when windows uses virtual memory which is your hard drive it does the same thing writes to the first blank space it sees so if it has to jump all over the hard drive finding little bits of space it is going to slow you down, where as if all the free space in pretty much in a continuous line then less time is taken to access it. One hint though is to set your virtual memory to a certain size so that it isn't always changing to fit it's wants, as this to will help keep it all together

Defragmenting your hard disk is a great way to boost the performance of your computer. Though the term "defragment" sounds a little abrasive, it is actually a simple and helpful process. After all, a defragmented hard disk is a happy hard disk.Adding and deleting files from your hard disk is a common task. Unfortunately, this process is not always done very efficiently. For example, when you delete a bunch of little files and add a new large file, the file may get broken up into mulitple sections on the hard disk. The computer will still read the newly added file as a single valid file, but the drive will have to scan multiple parts of the disk to read it. Because hard disk seek time is one of the most significant bottlenecks in a computer's performance, this can drag down your computer's speed quite a bit. If you have a ton of "fragmented" files on your hard disk, you might hear extra grinding, sputtering, and other weird noises coming from your computer. You computer does not like having fragmented files any more than you do. This is why defragmenting your hard disk is such a good idea. When you start to hear extra grinding sounds, or your computer doesn't open files as quickly as it did before, it's time to defragment. With Windows, you can use the pre-installed Intel defragment program to defragment your hard disk. You can also use a commercial software program like Norton Utilities to defragment your hard disk more efficiently and with more options. For Mac users, a disk utility such as DiskWarrior or Tech Tool Pro is the only way to do it. If you use your computer daily, defragmenting your hard drive once a month should keep the fragment-fiends away. I hope my answer to your question will give you some help

Answer 4

The process of rearranging the programs on the hard disk in a continuous way is called disk defrag. You need to defragment your disks because fragmentation slows down your computer considerably, since Windows must find all the pieces of the fragmented file (which is spread all around the hard disk) in order to load it. An average user needs to defrag disk once monthly. However if you use your computer about 7 hour per day, you will need to defrag your disks every three weeks.

Answer 5

Over time, your disk gets fragmented as a result of adding, deleting and modifying documents, e-mails, etc.
A defrag pulls all of the elements of your data together and reduces the number of disk seeks. It also moves your data to fill in the gaps and eliminate wasted space. So, two benefits:
1. Your systems responds faster.
2. Your disk has more usable space.

I would do a defrag at least once a month.

Answer 6

Think of the files on your hard drive a you would your CD collection. Once a year you put them all in order, either alphabeticaly or by artist. Any time you want to hear a certain CD you know right where it is. After a while, you get lazy, dont put disks back in the right boxes, leave some in the changer, or just toss em on the shelf anywhere. Once day you are dying to hear that special song, and you go nuts looking for the CD. After that happens a few times you bite the bullet and spend a couple of hours reoganizing your collection.

Answer 7

FACT: The computers slowest part is the Hard Drive.

It sorts files on the HDD (hard disk drive) to make it read faster.

Someone said "If you had a Mac, you wouldn't need to defrag, since the OS does it on the fly." that means MACs write to the HDD slower then PCs

If you don't care about speed then don't bother. But most people care about speed so do it.

Answer 8

Defragmenter re-locates data being distributed through out hard drive. Which means every activation of a certain program data is being stored randomly... By using Defrag it relocates all the data back to it's original place so that accessing data will be much faster...

Answer 9

Filling a hard drive with programs is like filling a row of boxes with items in them. If one item (file) fills the box, the next one is filled and so on. After you fill a row, you find you have like items that were supposed to go into the third box, so to have all items together you shove all the boxes down, put an empty next to 3 and continue filling..
Most drives are formatted to 4096 bytes per sector,when a sector gets full, parts of the file are written in the next sector. If that sector is full, it will go to the next available sector. After a while your computer slows down because the files are scattered all over the drive(fragmented). Defrag lines all the boxes up in neat rows again, with all parts of the file together.

Answer 10

Unlike others, I almost NEVER defragment my computer at all. I have no problem accessing datas on-the-fly, when I need it, without any problem whatsoever; I'm not a big fan of spending 5 hours+++ to shave .01 to 1 second off each task. Essentially, you are spending time to save time (very minimum amount).

Why should you? You shouldn't. I wouldn't bother.
