Disk defragmentation
The process of rearranging the data on a storage medium, such as a hard disk drive (HDD), for efficient storage and access
Process
Fragmented files
Files no loner kept together neatly, they are in random places
-
Defragmented files
A defragmentation utility will rearrange all the files so that each file is contiguous using the free spaces from deleted files
-
Hard disk
- Platter - This is the vinyl record, so to speak; the disk that contains the sectors and tracks (all the info).
- Spindle - This is the core that runs the platter and determines the speed of the spinning, measured in revolutions per minute (rpm).
- Head - This is the "needle" that reads the data from the platter. When this head is knocked off balance or fluctuates, your drive crashes.
- Arm - This holds the heads in place, and moves them around the platters when the disk is seeking a track or sector.
- Actuator Axis - This holds the arm in place—and is another component that, if disturbed, could cause a drive failure.
- Actuator - This is the device used to move the actuator arm to different positions to read from the disk. Because it changes the head from track to track, it is the only part in the disk besides the platter that moves actively—changing heads is done electronically, and waiting for the right sector to show up under the head is done passively.

Formatting
-
If it a used disc then all data will be lost, and prepared again as if the disc was being used for the first time
-
