Fragmentation and Defragmentation is secure?

25 August 20082 Comments

Last week i read some articles on defragmentation utilities and defragmentation , but nobody tell when it is really required and how secure it is ? So here i want to share these things.

Fragmentation is caused by creating and deleting files and folders, installing new software, and storing various files, downloading files from the Internet. Computers do not necessarily save an entire file or folder in a single space on a disk; they’re saved in the first available space. After a large portion of a disk has been used, most of the subsequent files and folders are saved in pieces across the volume. When you delete files or folders, the empty spaces left behind are filled in randomly as you store new data. The more fragmented the volume is means the slower the computer’s file input and output performance.

Disk fragmentation leads to system slowdowns, PC crashes, slow startups and shutdowns.

Fragmentation makes the disk drive heads move too much when reading files which turn to system crashes. It is important to keep your disks defragmented and optimized as much as possible.

Defragmentation is the process of rewriting non-contiguous parts of a file to contiguous sectors on a disk for the purpose of increasing data access and retrieval speeds.

Some defragmenters also try to keep smaller files within a single directory together, as they are often accessed in sequence. Defragmentation reduces data access time and allows storage to be used more efficiently.

When we need to do defragmentation

What I found is lot of peoples doing defragmentation regularly but my experience says that doing defragmentation regularly is also damage disk because it does this by physically reorganizing the contents of the disk to store the pieces of each file close together and contiguously. It will create bad sector in disk, make problem in data reading, and also decrease magnetic flux around disk.

Defragmentation required to keep your disk faster and safe. So I will suggest you, do fragmentation when you face slow startups and shutdowns, system slowdowns, slower data access. Also lots of free utilities are available for defragmentation, so use good one.

    Hi… as long as i know the head of the hard drive has NO CONTACT with the disk which means the more you work will not affect the disk and so no bad sectors…

    as a suggestion for a good defragmentor i can say : Norton SpeedDisk … but it comes with a price to buy the norton systemworks or you need to get a pirated copy…

    thanx again
