Windows system disk bad sectors how to repair and use

hard disk use for a long time may have a variety of problems, and the hard disk "bad track" is the most common problem. In addition to the quality of the hard disk and the cause of aging, the hard disk is mainly due to the fact that it is not suitable for the hard disk in normal use. For example, the memory is too small, so that the application software frequently accesses the hard disk, the hard disk is excessively defragmented frequently, and the overclocking is inappropriate. Poor quality, high temperature, poor dustproof, vibration, etc.

The most delicate part of the computer should be the hard disk. Although this situation has changed with the continuous advancement of the manufacturing process, some hard disk manufacturers such as Quantum have also released related new technologies, such as the SPS vibration developed by Quantum 7th generation to reduce the impact of the hard disk. The protection system, in this way, counts on the body of the hard disk & "careful". But the shortcomings of the hard drive are not fundamentally changed. For those who like to chase new computer
users, the update frequency of the hard disk is generally not as fast as the CPU or the display card - even if you want to buy a new hard disk, the old hard disk should be hung in the chassis to play the heat, so people are special I don't want to see the hard drive fail, especially when the precious data is saved on the hard drive. The hard disk is logically damaged. It is not a big deal to reinstall the software, but the physical damage? In fact, as long as the situation is not particularly serious, using some methods to deal with it can generally solve the problem.

First, let's take a look at the physical damage of the hard disk, that is, what happens after the bad track.

1. It often goes wrong when reading a file or running a software, or it takes a long time to operate successfully. During this time, the hard disk keeps reading the disk and makes a harsh noise. This means that the hard disk is uploaded. Some sectors with data are bad.

2. The system cannot boot through the hard disk when booting. After the floppy disk is booted, 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. This situation is more serious because it is very likely that there is a problem with the boot sector of the hard disk.

3. A blue screen appears frequently for no reason when using the computer normally.

For the first three cases, we generally have a way to remedy more or less. Here are a few ways to fix bad sectors on your hard drive. Note that the top-ranked approach should be prioritized.

1. Start with the easiest way. In the Explorer of Windows
98, select the hard drive letter, right-click the mouse, and select “Properties> in the shortcut menu to completely scan the hard disk in the <quo;Tools> And automatically correct the possible bad clusters. For the second case above, you cannot enter the Windows
98 phenomenon, you can use the boot disk of Windows
98 to boot the machine, and then at the "A:>" prompt Type “scandiskX:” to scan the hard drive, where "X” is the specific hard drive letter. For bad clusters, the program will be marked with a black text in the form of "B".

2. In fact, the first method often does not work, because Windows98's automatic repair of "bad sectors" is largely for logical bad sectors, but can not automatically repair physical bad sectors. Therefore, it is necessary to consider "bad treatment" for these bad sectors. The so-called "cold treatment" is to mark these bad sectors, not to use, can not afford to hide. Remember the location of the bad track in the first method, then format the hard disk advanced, divide the area with bad sectors into a zone, and do not access the files in this zone later. It should be noted that, do not make this area too much to save the hard disk space, "economic", and should have appropriate room, because reading the "good road" around the bad track is not wise - bad The road is invasive. If you use the “good road” that is too close to the bad track, then it will not take long before the new bad track on the hard disk will appear again.

3. Use some software to deal with the hard disk, the most typical of which is PartitionMagic. Take the 4.0 version as an example: Scanning the hard disk can be done directly with the “check” command in PartitionMagic4, but the command has no automatic repair function, so it is best to call Windows98 related programs in PartitionMagic4 to complete this task. After marking the bad cluster, you can try to retest it by selecting ““Advanced/badSectorRetest” under the Operations menu. After dividing the bad cluster into one (or more) zones, you can consider hiding the zone to avoid In Windows 98, this function is implemented by the HidePartition menu item. It is important to note that if the partition with bad clusters is directly hidden without formatting, then the subsequent partitions of the partition will cause some of the characters related to the drive letter to not run correctly due to the change of the drive letter. Some software shortcuts created on the desktop will not find the host program. The solution is to use the DriveMapper menu item under the Tools menu. It will automatically collect shortcuts and related information in the registry and make them correct. modify. In particular, in the newer version of PartitionMagic5.0Pro, DriveMapper has also been upgraded to version 3.0, making this work more efficient and concise. In addition, the DiskManager software can do this work. After hiding the partition, don't try to merge the front and back partitions of the partition where the bad track is located - that is futile because the two partitions are not physically contiguous.

4. For the case of 0 sector damage of the hard disk, it seems to be tricky, but it is not helpless. - Just block the scrapped 0 sector, and replace it with 1 sector. The ideal software for this job is Pctools 9.0. Specifically, it is the DE tool in Pctools 9.0. It should be noted that after the modified sector is completed, the information of the partition table will be written only after formatting the hard disk. Enter 1 sector (now as 0 sector).

5. It is best not to use this trick: it is low-level on the hard disk. Because there are at least two disadvantages to the low-level hard disk: one is the wear disk, and the other is the hard disk with bad sectors, the low grid will accelerate the spread of bad sectors.

6. Finally, there is a point, that is, the relevant content of the motherboard BIOS should be set properly, especially for some motherboards before the TX chipset level, because there is no ability to automatically identify the hard disk specifications, often due to improper settings And affect the use of the hard disk, the hard disk can not make the best use of it, but also damage the hard disk.

The above describes the solution to the physical damage of the hard disk. However, most of these methods are negative, at the expense of hard drive capacity. The hard disk has bad sectors. If it is not because of aging problems, it means that there are some irregularities in the use. For example, the hard disk is defragmented too frequently, and the memory is too small, so that the application software frequently accesses the hard disk. Ignoring the dust-proof processing of the hard disk can also cause the mechanical head of the hard disk to cause mechanical failure due to difficulty in positioning. In addition, the CPU overclocking causes the FSB to increase, forcing the hard disk to work under excessive voltage for a long time, which will also cause a malfunction. Therefore, the use of the hard disk should be handled with caution.

The hard disk is a computer storage device that integrates precision machinery, microelectronic circuits and electromagnetic conversion. It stores computer system resources and important information and data. These factors make the hard disk the most important in the PC. A hardware device. Although the trouble-free working time (MTBF) of brand-name hard disk can exceed 20,000 hours —— it can be used normally for more than 5 years according to 10 hours of work every day, but if it is used improperly, it is very easy to malfunction. Even physical damage has occurred, causing the entire computer system to not work properly
