What is Minning of Disk Defragment ?

Answer 1

In the simplest terms, it means rearranging the contents of your disk so that fragments of a file are stored close together.

This improves your system's performance by speeding up reads on your hard disk.

Answer 2

The more you use your computer, the more data is stored on your hard drive. Think of it as a giant vinyl disk player (the old school ones :P). Hold the needle up off of the disk. Whenever your computer writes data, it will just push down the needle onto the disk and start writing at the first available location while the disk keeps spinning. When it finishes writing, the disk continues to spin even though the needle is no longer touching. After extended periods of raising/lowered, there will be many small gaps between one block of information and the next. When you do a Disk Defragment, it will re-organize all the data that is store on that disk into a logical order, pushing all the used data to the front of the disk, leaving a very large space of "empty" space that can be written to all in the same location. Kind of like organizing all your files into a filling cabinet, putting all your files in the back and leaving the front empty.

Answer 3

In order to be as fast as possible in writing, (not having to wait while the file is moved to a bigger location), when files are stored under modern operating systems, they are written down in scattered locations on the disk and a list is kept of the locations. This is especially true of files that start small and grow over time, like databases. If files that are used a lot are fragmented all over the disk, then the disk access slows down as the head is jumped all over the disk. This is especially bad if a search in undertaken.
So what Disk Degragment does is look through the list of files and the available empty storage and it carefully shifts the files so all the sections are together and the file can be read from beginning to end with minimal changing of tracks. It is kind like taking a magazine that has a lot of stories continued later in the mag and cutting up the pages so every story has all its contents stapled together for easy reading.

Answer 4

A disk drive starts off by being a blank slate and then files get written and more files get written. This is not a problem until files get shortened or deleted. Suddenly there's holes (unused space) where a file used to be. It might not be enough to hold a whole file, though, so these are often skipped over for one that is.

Ultimately, though, you run out of space, even though you might have enough unusued space - just not all in one place. So what disk defragmentation does is go through the list of files and write them back onto the disk in a way that keeps them together and effectively minimizes any "holes" in the layout area you might have.. Particularly required with the older FAT, not so much the newer NTFS (both are recognized storage formats on disk.

Answer 5

Meaning of disk defragment?

Defragmentation puts all the pieces of data that form a file into a continuous number of disk sectors. THis speeds up disk access because the heads dont have to move so much. Many seeks take excess time and slow the system down from data access.

Answer 6

Think of your computer as a bookshelf. And files are books. Now, let's say that you have an application that you run often. And this application has many files to run. Then, let's say that this application is a set encyclopedias. When an application is run, the computer places files in available clusters in memory. After you run this application, the files sometimes don't get put back into the correct sectors. Therefore, what defragment does is gather those files (or encyclopedias) and place them back on the bookshelf in the correct order so that the application can gather these files (books) again later. Putting these "books" on the shelf in order will allow your computer to run a little bit faster because the computer doesn't have to search for these files all over your computer's memory because they will be organized together.

Answer 7

when you install or use your computer on a regular basis more of the data stored always gets stored in sectors that have a lot of free space. For example if a file as to access a dll file stored many sectors away it will have to rotate the harddisk so many times. By using defragmentation you bring the files closer to the present sectors. Defragmentation is mandatory once every 14 days. This is essential to speed up your computer and maintain it condition.

Answer 8

Over time when Windows stores files over your HDD, it gets stored as non sequential peices scattered across the drive. This is called fragmentation. For Eg:

3 files stored initially
AAAABBBBBCCCC

The second file removed
AAAA-----CCCC

A 4th file saved- as fragments
AAAADDDDDCCCCDD

When the drive is fragmented, the HDD head has to mechanically 'go'to each fragment and read it, increasing the time taken to access the file, which leads to slow opening of programs etc. If this were only for a couple of files, the difference may not be noticed. But the problem with fragmentation is that once it starts, its like a spreading disease which leads to subesquent disarray and slowdowns. In severe cases, it can pose a potential threat to drive health and lead to hangs/freezes etc. The lesser the fragmentation, faster the PC. Imagine if you had to run a marathon with a knee injury, that would be the state of a fragmented drive.

The link you have given is of a freeware tool. You can check out trial versions of various tools in the market before deciding what to run, but its a good idea to stick to one.

Answer 9

disk defragmentation means putting the data on the continuous disk sectors the are scattered on the disk
this process puts the data together and increases the speed of data retrieval

Answer 10

i think you mean to say meaning instead of minning... defragmentation is a process wherein your system reorganizes the contents of your disk and store them close together, thus it creates a larger area of free space. this process is recommended to keep your access to your disk from degrading over time..

i alsot inspects your hard disk to find out if there are any bad sectors, or bad clusters..
