Hard disk damage repair
The most finicky computer components should be hard drive. Although the manufacturing process with the continuous progress, this situation has changed, a number of hard disk manufacturers such as Quantum also issued a related new technologies, such as Quantum seven generations in order to reduce the hard drive started by the impact shock developed sps protection system, as the body count on the hard disk "strong" together. However, the shortcomings of a bad hard drive easily, and has not been fundamentally changed. The hard drive to save the precious time of data. The hard disk is a logical damage be it, big deal to reinstall software, but the physical damage it? In fact, as long as the situation is not particularly serious, with some means, and in general can solve the problem. First, let's take a look at the hard disk has physical damage, that is, after what has been the phenomenon of bad sectors.
1, read a file or run a piece of software often wrong, or to operate successfully after a very long time, during which continued to read the disk drive and issued harsh noise, this phenomenon means that the hard drive containing data on some of the fan area has been bad.
2, boot the system can not boot the hard disk, floppy boot disk can be transferred after the letter, but can not enter, with the sys command conduction system can not succeed. This situation is more serious, because it is likely that the hard disk boot sector out of a problem.
3, normal use of a blue screen when the computer frequently for no reason. For the previous three kinds of situation, we generally have a way to make more or less remedial. The following provides several ways to fix bad sectors on the hard disk should be noted that priority should be given top surface method.
1, scan the hard disk. First, from the most simplest way to start. In Explorer, select the drive letter, right-click on the shortcut menu, select "Properties" in the "Tools" item on the hard disk to make a full scan processing, and on the possible bad clusters for automatic correction. For the above situation in the first two kinds of phenomena that can not enter the system, you can boot the machine with the boot disk, and then in "a:>"? Prompt, type "scandisk? X:"? To scan the hard disk, where "x" is a specific hard disk drive letter. For the bad cluster, the program will be black red of the "b" (bad) are marked.
2, cold treatment. In fact, the first one kinds of methods often does not work, because of "bad sectors" auto repair is largely in terms of the logical bad sectors, but not automatically repair physical bad sectors, it is necessary to consider these bad sectors as " cold treatment. " The so-called "cold treatment" is to make mark in these bad sectors, do not use, untouchables also avoid them since. 1 ways to remember the location of the bad sectors, and then high-level formatting the hard disk, there will be bad sectors in the region divided into a zone, then went to access this area, do not file. I want to clarify is not to save hard disk space for this division was too much "economic", but should leave appropriate leeway, because to read bad sectors around the "good" was an unwise - with the spread of bad sectors , if used with bad sectors relying too close to "good Road", then before long, the new bad sectors on the hard disk in turn appear?
3, with some software for the hard disk for processing. One of the most typical is the partitionmagic. Here for 4.0 version, for example: Scan the hard disk can be directly partitionmagic4 in the "check" command to complete, but the command no auto-repair function, so it is best to call in the partitionmagic4 associated procedures windows98 to complete this task. 3,0 sector is damaged. For the damage to the hard disk 0 sector the situation looks difficult, but not incurable - as long as the scrapped 0 sector shielding, but instead on the line with a sector, and the completion of this work, the ideal software is pctools9 .0, specifically, is pctools9.0 in de tools, to note that, in changing sector is completed, only the hard disk partition table will be formatted before the information is written to a sector (now as a 0 sector of).
4, low-grid. Less than a last resort, this move is best not to use: namely, the hard disk for low-grid. Because of the hard disk for low-grid there are at least two harmful effects: First, wear disc, and second, to have the hard drive for bad sectors, low-grid will accelerate the proliferation of bad sectors. Finally, there is that it is related to the contents of the motherboard bios to be set up properly, especially for some tx level before the motherboard chipset, the absence of the ability to automatically recognize the hard disk size, often a result of improper settings affect the use of hard drives, ranging from the hard disk can not make the best use, while in the hard disk damage. Described above is the hard drive when there is physical damage solutions. However, these methods are mostly negative, at the expense of the hard disk capacity at a price.
With the hard disk bad sectors, if not because of the problem of aging, then usually in the use of something wrong, such as the right too frequently defragmented the hard disk, memory, hard drives too few applications to the frequent visits. And ignore the dust on the hard disk drive heads because the deal will lead to difficulties in positioning lead to mechanical failure. In addition, the FSB cpu overclocking caused by increased, forcing a long drive to work at too high a voltage will cause malfunction, therefore, usually use the hard drive should be to exercise caution as the best way
