Hard disk is a very special fittings in PC, the value of its itself does not calculate big (at present the hard disk of 160G capacity is not worth 600 yuan) , but the value of the data that bears the weight of on hard disk is to cannot use exact number to measure however. Look especially according to current hard disk capacity, major computer user is the product of use 100G above, high capacity hard disk stores huge data while, also having an apparent reason: If your hard disk appears problem, so all data can have missing risk, the data bulk that hard disk bears the weight of is greater, mean a loss bigger, especially disk array, the cost that data recovers is the value that exceeds hard disk itself far.
Of course, to average user, data does not have what commerce value it seems that. But the data that this differs to tell an user at saying general can be lost casually, say for example, some user comes for years part of the photograph of collect carefully, movie and data of a few people are like a diary to once lose,wait, although look,be like without what immediate pecuniary loss, but these data are likely to this user of dispute Chang Zhengui; Additional, the word of hard disk occurrence problem also can let a system break down inside proper time, the trouble that cause also cannot be ignored. Show according to investigation, the machine rate that PC system breakdown exceeds 20% is caused by hard disk, maintain daily so as bigger as the sense that maintains the job, correct use and safeguard not only can let hard disk prolong life, the trouble that because data is missing,can be absolved more and brings even pecuniary loss.
The internal composition of hard disk
Although is outer ministry structure respect, there is certain distinction between all sorts of hard disk, but its interior structure is basic and identical, after all the substaintial work way of hard disk won't be changed. The core part of hard disk interior includes electric machinery of dish of body, main shaft, read/write head, search electric machinery to wait. What need to remind everybody nevertheless is, must not open the case of hard disk at will below common environment, the interior because of hard disk dish the face cannot is infected with on dirt, discard as useless instantly otherwise.
The path of the maintenance of hard disk
Should undertake maintaining normally to PC fittings actually with maintenance sentence, with respect to the character that must know fittings itself, the operation that has harm to its especially must understand, can avoid so and go. We can undertake maintenance respectively according to the characteristic of hard disk.
