How to clean up Hard Drive on your Computer - Clean my PC Free.

A brief explanation of Hard Drives.

The hard drive stores information such as the operating system, word processor files, music, videos etc. It stores this information on a magnetic disk. Turning on the computer starts the hard drive which spins, the speed depends on the make of drive. A central spindle holds the disk in place, digital information is then written to the drive by an arm which has a tiny magnet on its end.

The read-write arm.

An actuator or a servo is controlled by a motor which moves the arm across the disk electronically writing a series of zeros and ones, or on and off, these are called binaries. This magnetised information stays on the drive even when it is turned off.

Partitions, sectors and tracks.

This drive is made of partitions. At the beginning of a partition is a File Allocation Table or New Technology File System. When the computer wants to read some information off the drive, it looks at this table which points to the area where that information is. This information is kept on a tracks sector. The read/write head either magnetises or de-magnetises the magnetic disk. When a particular part or file on the drive is no longer required, the information isn’t destroyed, it remains on disk, this is why it is possible to recover deleted files. What is altered is the file allocation table or new technology file system which is told there is no information in that track on that sector. This is why it is so important to format and wipe the drive before disposing of.

Solid-state drive


Hard disk drives are slowly becoming obsolete. The new technology is solid-state drives which act very similar to random access memory. They are faster and much less likely to fail. Anyone who has dropped their laptop on the floor and found the system no working will tell you this. Over some time, the drive becomes cluttered with all sorts of junk such as temporary files etc. Keeping the drive in tip-top condition improves efficiency.
