Computer hard disk is more easily damaged parts, but one reason is a considerable part of the user is caused by improper operation. In fact, as long as the attention of some small skills in daily use, they can reduce the possibility of hard drive failure, thus prolonging their normal life. 1 read and write off the bogey disk rotational speed is 7200 rpm, in reading and writing, the disc rotating at a high speed, if suddenly cut off the power supply, the head and disc violent friction, resulting in the hard disk bad sectors or even damage. So in the shutdown, attention must be paid to the hard disk light panel is no flicker, the hard disk has been completed after the read and write operations can shut down the computer according to the normal procedure. 2 prevent shaken hard disk storage devices are very sophisticated, read and write operations, head in the flying height of the surface of a disk of only a few microns; even when it does not work, the head and the disc is contact. Hard at work, the event of a large earthquake, it is easy to cause the head and the data collision, resulting in the disc information area damage or scratch disk, missing file data stored in hard disc. Therefore, in the work or shut down after the spindle motor has not been stopped before, do not move the computer or mobile hard disk, in order to avoid head disk impact and scratch the surface of the magnetic layer. In addition, more careful in hard disk installation, disassembly process should be, preventing excessive shaking or with the chassis plate collision. 3 away from the magnetic field is damaged invisible killer hard disk data, so as far as possible to make the hard disk not near a strong magnetic field, such as the sound box, mobile phone, radio, so as not to record information on the hard drive is damaged due to magnetization. 4 reducing the frequent operation if long time running a program (such as large software or games), then we must pay attention to the head, so a long time frequently read and write the same disk position (i.e. the program where the sector), and make the hard disk bad sectors. In addition, if long time use of an operating system, also can make the system file where the hard disk sector (non mobile) in a long read state, thus speeding up the damage rate of the sector. Of course, it is best to install two or more alternative use of operating system, to avoid a long hard disk sector read and write operations. 5 the proper use of the time in a day, it is best not to let the hard work more than 10 hours, and not to work more than 8 hours, should shut down the computer after using a period of time, so hard to have enough time to rest 6 regularly defragment hard disk work frequently read and write operations at the same time, increase, delete the program will generate a lot of discontinuous disk space and disk defragmenter. When the number of discontinuous disk space and disk fragmentation increased, it will affect the effectiveness of the hard disk read. If the data to the operation more frequently or constantly changing software, it should be at a certain time (such as a month) to run the windows system comes with the disk defragmentation tool, disk fragmentation and reorganization of discontinuous space, will play to the best performance of hard disk. 7 increase memory and good power supply if often use some memory needs great software (such as image processing, model design software), you should increase the memory, to reduce the amount of files on the hard disk exchange when the read and write operation, thereby prolonging the service life of the hard disk. In addition, we must supply stable performance, if the power supply impure or power shortage, it would be easy to cause data loss or damage to the hard drive.
