硬盘工作原理（国外英文资料） Let the pseudoscience go to hell - whether the hard drive is really hurting hard drives and FLASHGET really hurts the V5 version of the hard drive In advance, I just mentioned FLASHGET, I didnt mention ED and FTP because theyre all the same, and I dont want to do a typing I emphasize, Im just talking about FLASHGET here, but its the same thing with ED and FTP as the same as the so-called loss of the hard disk. Take a quote from someone Why does frequent reading and writing damage the hard disk? Head life is limited, so frequent, speaking, reading and writing will speed up the motor head arm and head wear, frequent, speaking, reading and writing disk will make the temperature more, a region that will affect the stability of magnetic medium can also lead to read/write error, high temperature will make the area expanding with heat and make closer to the head and dish (normally head only a few microns, and dish also closer?) , but also affects the data of a diaphragm head read sensitivity, can make the crystal oscillator clock frequency change, also can cause hard drive circuit component failure. Various tasks will also lead to premature failure IDE hard disk, the shortage of IDE hard disk itself, task request is too much can make seek frequent failure rate rise to head reset (reset is to head back to zero track, so that to seek) speed motor wear head arm and head. Let me start with the modern hard drive Todays hard drives, both in the IDE and SCSI, use the Winchester technology, which features the following features: 1. Magnetic head, disc and movement mechanism seal. 2. The surface of the plated disc with fixed and high-speed rotation is smooth and smooth. 3. The head of the head moves in radial direction. 4. The head of the head is stopped by the disc, but it is not in direct contact with the disc at work. Disc: hard disk is the magnetic powder, adhere to the aluminum alloy (new material also useful glass) on the surface of the disk. The magnetic powde
