What its Hard Disk Defragmentation
Hard Disks are the slowest device of your computer because of the mechanical movement of the head involved for the data retrieval. Keeping all other things constant, if you can make the movement of the hard disk head to be minimum for the same data transaction, the performance of your computer will increase.
This is the principle behind the defragmentation of hard disks. Data storage in the hard disks is in the form of files and these files are not stored at one place in the hard disk. The content of one file may get stored at several locations, which may not be contiguous, depending upon the availability of free sectors at the time of storage of the file.
Over a period of time, your hard disk may become several partially filled sectors and to store any new file, your computer may not find one place to store the file. In such case, it fragments the file into several pieces and stored them at different locations, all linked to one another with the help of the directory structure.
Hard Disk De-fragmentation if the process of re-arranging this data, so as to ensure that file contents are stored in contiguous sectors as far as possible. This avoids unnecessary head movement and saves lot of precious time in the retrieval of data and increases the speed and performance of your computer.
How to Defragment Your Hard Disk

Free space consolidation: The more fragmented the free space is, the more fragmented new files will be. Disk Defrag merges free space into a large contiguous block.
System files smart placement: Auslogic Disk Defrag tool minimizes the time needed for HDD to access system files improving overall computer performance.
Keeping the MFT Reserved Zone Clear: Normally, NTFS file system reserves about 12.5% of the disk volume for the MFT records (a place where information about every file and directory is stored). However, when the rest of the disk space is getting low, the MFT Reserved Zone will be used for storing regular files. This may lead to MFT fragmentation.
Disk Defrag 3 replaces regular files from the MFT Reserved Zone into the rest of the disk space, allowing NTFS to allocate contiguous space for the MFT records and thus to prevent its fragmentation.
