What is defragmentation?

Disk fragmentation occurs when a file is broken up into pieces to fit on the disk. Because data are continually being written, deleted, and resized, then there are more and more fragments. The resulting impact of fragmentation is slow PC performance, long boot-times, random crashes, and freeze-ups – even a complete inability to boot up at all. So when a file is spread out over several locations, it takes longer to read and write. Many users blame these problems on the operating system or think their computer is "old," while hard disk fragmentation is often the real culprit.



Sometimes, you try to speed up your computer by running a disk defragmenter, but cause programs or large files broken up or fragmented. This is terrible for us because once the data is lost due to defragmentation, it is hard to recover. Therefore, you can back up existing data and recover lost data before defragmenting the disk.
Will defragmentation harm my HDD?

Don't worry: Mac OS X defrag will not harm your HDD. As you already know, disk defragmentation can significantly speed up the traditional hard drive. It's because HDD fragments all the data and stores it in multiple locations. And it may take quite a time to read the file with its pieces situated in different places. The procedure for arranging the data is not harmful to your HDD and is aimed at boosting the computer's performance. While it is not advisable to turn to such extreme measures, defragmenting a hard drive disk is a safe procedure.
