A hard disk drive, commonly referred to as a hard drive, hard disk or fixed disk drive is a non-volatile storage device which stores digitally encoded data on rapidly rotating platters with magnetic surfaces. 50% of the world's neodymium magnets are currently used in computer hard disk drives with each hard disk drive typically containing two magnets. The magnets used in hard disk drives are very strong neodymium (rare earth) magnets. They are made of a mixture of neodymium, iron, and boron. The magnets are used in the actuator - a device which moves the actuator arm on the tip of which is the head which reads and writes data to/from the ultra-delicate platters. Driving the arm using magnets means that mechanical wear and tear is not an issue - unlike old-fashioned stepper motor powered hard drives. Hard drives are sophisticated devices thus to change any internal components or even for diagnosis we require the correct tool set .The Magnet exchanger tool removes most magnets from hard drives without damaging the read write heads, sensors or platters. The magnet is placed above the read write head so whenever there is requirement of removing read write head or platter firstly magnet has to be removed. Why is it important to use hard disk magnet exchanger tool? Dropping a magnet on the platter will scratch or damage the platter thus the hard disk magnet exchange tool is used which hold the magnet until the magnet is a safe distance away from the platter. Earlier there are conventional ways used for removing the magnet from hard disk which were not adequate as for example with pliers, hand etc, due to which loss of data take place and with hand the magnet losses its magnetic power too. If magnet were dropped on platter scratches or shocks could take place which cause data as well as economical loss. Now in this upcoming technological era Magnet exchanger tool has been generated which has easy way to operate with the magnet. Benefits of using hard disk magnet exchanger tool: The magnet will be placed properly without damaging to the platters or head .The tool can be used to remove the magnets holding the heads in place when the need arises to replace the heads after a hard disk head crashes. The tool is very easy to use. The struggle with pliers or other tools or with hand is over.
