The need of Defragmentation of HDD and How to do it?

Reading time: 2 min

Nowadays, most of the computers and personal PC runs on SSD but there are many devices that run on HDD. The response speed for reading and writing a file from HDD decreases if proper defragmentation is not provided to the disk. The term defragmentation is just the opposite of fragmentation.

When the disk gets formatted and new records get to return the data which is written to the disk is written in a straight line but when we delete some files the area that holds that data gets free. When the new record comes for the storage it gets stored in the disk area which is free which means the file gets stored into multiple locations. When reading this file the disk needs to run multiple times instead of one time to gather all the locations of the file which makes the whole process slow.

Defragmentation reverses these effects by doing two things. First, it reassembles any files that have been broken into little pieces and places the files in just one physical location. On your disk resulting in faster access. Second, it rearranges most of the free space on your drive into one large continuous chunk so that your PC won’t try to fragment new files or information and give you them up into little storage holes and free space.
