Hard drive maintenance Raiders Let your love machine last longer

Hard drive can be said to be the most fragile and most expensive accessory in the computer. The damaged working sound of the three-stage IBM hard disk announced on PCPOP makes us creepy. At the same time, because the hard disk has important information of the user, it is one of the most commonly used and most important storage devices in the microcomputer system, and is also one of the devices with high probability of failure. Therefore, everyone will try their best to save the hard disk. The faults from the hard disk itself are generally small, mainly due to human factors or the user does not take practical maintenance measures according to the characteristics of the hard disk. Therefore, the hard disk must be properly maintained during use, otherwise it will malfunction or shorten the service life, and even cause data loss, causing irreparable loss and inconvenience to work and life. Today, I will explain to you the reasons for the hard disk failure and how to maintain it daily.

Where is the hard disk often broken?

First of all, we have to figure out where the hard disk is often bad, how is it bad, In this way, it is possible to prescribe the right medicine and achieve twice the result with half the effort.

1, logical bad sectors: commonly known as "soft bad sectors". It is caused by software installation or use error, and generally does not cause too much harm to the hard disk itself.

2, physical bad sectors: such bad sectors are the common symptoms of the previous IBM hard disk incident. The gap between the head and the disk is only 0.015~0.025 μm. With such a small gap, if the hard disk is in transit, if it is subjected to strong bumps, the hard disk will cause physical bad sectors. In addition, human error will also scrap a hard drive. When some careless people installed the machine, the hard disk screws were not tightened, which buried hidden dangers for future use. The vibration of the hard disk can also cause physical bad sectors.

3, zero track failure: As we all know, the hard disk read disk starts from 0 track. If the 0 track is damaged, it will cause the hard disk to be unable to read the disk, the boot cannot find the hard disk, and so on.

The above three kinds of calculations are common and difficult symptoms of hard disks. Logical bad sectors are typhoid in hard disk failures, which are generally easy to solve and can be solved with the Windows ScanDisk. If you can't get rid of the disease, you can't make a FORMAT hard drive and reinstall the system. But for physical bad sectors and zero track failures, we have to spend some time and effort.

Symptom 1: When you open a file or run a program, the hard disk repeatedly reads the disk and makes a mistake, or you have to go through a lot of effort to succeed. At the same time, the hard disk will emit a strange noise; when booting, the system cannot be booted through the hard disk. After booting with the floppy disk, it can be transferred to the hard disk drive letter, but it cannot be entered. The system can not be successfully transmitted with the SYS command; The progress is stopped, and the final error is not completed. When FDISK is executed on the hard disk, it will go back and forth to a certain progress.

These symptoms are common symptoms of physical bad sectors. There are currently no good medicines for completely repairing physical bad sectors. This problem can only be alleviated by repairing a small number of bad sectors or shielding bad sectors.

1. Start with the simplest method. If you can enter Win9X system, use Win9X's own disk scanner, "Scan Type", select "Complete", perform a complete "check" on your partition, and find and repair potential bad clusters as much as possible. . For the above phenomenon that you cannot boot through the hard disk, that is, you cannot enter Win9X, you can start the system with the Win9X boot disk, and then type SCANDISK D at the A:> prompt: (where “D” is the specific hard drive letter) To scan the hard drive. For bad clusters, the program will be marked with a black text in the form of "B".

2. Because Win9X can only repair logical bad sectors, it is not enough to deal with physical bad sectors. So the first step will often not work, but in all the repair work, it is the most important. We can where the disease occurs. Make a mark on these bad sectors, leave it far away, can't afford it, always can't afford it. Remember the location of the bad sectors in the first step, then divide the area with bad sectors into a single area for the hard disk Format. If the bad sectors are not continuous and far apart, you can divide the adjacent bad tracks into one area. You can even draw more areas. It is worth noting that the area containing bad sectors should not be too compact for the hard disk space, and the appropriate "good roads" should be left around the bad sectors as a buffer. Don't access the files in these dangerous areas in the future, because the bad roads are diffuse. If you use the "good roads" that are too close to the bad sectors, then it will not be long before the disease spreads! 123 next page total 3 pages
