What is the purpose of defrafmenting hard disk?
Answers:
When a file gets fragmented, it loads slower. It gets fragmented when the file is modified by the editing program. During the editing process, parts of the file remain in the original location, and new (updated) parts of the file are stored elsewhere.
If you have not defragmented for a very long time, you should run this sequence of basic maintenance first.
- run Disk Cleanup - from the System Tools section of Accessories
- Open My Computer, then Right Click on your C drive and pick PROPERTIES. Pick the Tools section and click on CHECK NOW. Check both tests, and YES, let it run after you restart. You see, CHECK DISK will ensure that your hard drive is working completely. This test might take an hour or so.
- THEN run DEFRAG - from the System Tools section of Accessories.
Good luck and Happy Computing!
defraging your hard disk can lead to faster computer speed.
Microsoft provided us with a utility to organize the sequential layout of our files on our hard drive. As we either add or remove programs from our computer, doing so can cause our files and programs to scatter themselves all over our disk drive. Then when we try to launch a program, our hard drive has to work much harder by searching many different areas of our drive in order to get that program to load for us. And this of course hinders our computer’s performance. So Microsoft’s Disk Defragmenter program addresses this issue by organizing all our programs and files on our hard disk in a sequential easy to search layout.

OK its like this. Get a book and tear out all the pages and scatter them all over the floor. Now try to read the book in order. You can still read the book but it takes you a long time to seek the information in the right order. Well defraging your hard drive does exactly that it puts all the little bits of the files in the right order so they are easier to find (thanks cause the individual bits are all together) - Obbiously this is faster!
You see as you delete something it leaves space to put new information - the problem is it might not be big enough to fit the whole file - so only a small part is stored there - the res somewhere else.
Hope that helps!
It optimizes the speed by which a file can be accessed..
For instance...
Suppose you have a 10-page document you want to store in a file cabinet.
Now suppose none of the drawers in your file cabinet had enough space for the whole 10-pages to be stored together, but it has room in drawer #1 for 2 pages, room in drawer #3 for 3 pages, room in drawer #4 for 3 pages and room in drawer # 6 for the remaining 2 pages
How quickly would you be able to access all four of those drawers and pull together your 10-page document? Not as quickly as if you'd been able to file the whole document together in one drawer, right?
When you defragment your hard drive, your system pulls together all those "loose ends" (fragments) of files and re-files them in a single, cohesive manner.
This means that when you request a file (be it data, a document. a program, or other bit of "software")... the hard drive only has to be accessed ONCE, instead of 4 (or 50, or 150) times.
Hope this helps,

Reading and writing data on a heavily fragmented file system is slowed down as the time needed for the disk heads to move between fragments and waiting for the disk platter to rotate into position is increased.
Put simply, the information on your hard drive gets disorganised and so takes longer to find all the pieces, just like if all the books in a library were put away out of order.
