How to repair disk bad sectors in Windows system?

Computer Shop News The most delicate part of the computer should be the hard drive. 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 PC users who like to catch up with new ones, 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 (the computer automatically shuts down) to exert the residual heat, so people are not particularly Would like to see the hard drive fail, especially when the precious data is saved on the hard drive. Hard disk is logical damage, it is not a big deal to reinstall software, but physical damage, in fact, as long as the situation is not particularly serious, with some methods to deal with, generally can solve the problem. First of all, let's take a look at the physical damage of the hard disk, that is, what happens after the bad track. 1. When reading a file or running a software, it often fails, or it takes a long time to operate successfully. During this period, the hard disk continuously reads the disk and makes a harsh noise. This phenomenon means that some fans have data on the hard disk. The area is broken. 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 simplest method. Select the hard drive letter in the Windows 98 Explorer, right-click the mouse, select “Properties> in the shortcut menu, and perform a full scan on the hard disk in the <Tools> item, and the possible bad clusters Make automatic corrections. For the second case above, you cannot enter Windows98. You can boot the machine with the Windows 98 boot disk, and then type “scandiskX:” at the "A:>” prompt to scan the hard disk, 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, so it is necessary to consider These bad sectors are "cold processing". 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. Here (computer automatic shutdown) with 4.0 version as an example: scanning the hard disk can be directly used in the PartitionMagic4 “ check & rdquo; command to complete, but the command has no automatic repair function, so it is best to call Windows98 related procedures 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 continuous. 4. For the case of 0 sector damage of the hard disk, it seems to be tricky, but it is not helpless. Just shield the scrapped 0 sector and replace it with 1 sector. The ideal software to complete this work. It is Pctools9.0, specifically, the DE tool in Pctools9.0. It should be noted that after the modified sector is completed, the information of the partition table will be written to 1 sector only after formatting the hard disk (now As a 0 sector). 5. Less than a last resort, this trick is best not to use: that is, low-level hard drive. Because there are at least two low-level hard disks (the computer has no sound): one is wearing discs, and the other is that for hard drives with bad sectors, low grids 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, it will often affect the use of the hard disk due to improper settings. Lighter hard drives can't do their best, but damage the hard drive. 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. Hard disk has bad sectors, if it is not because of aging problems, it means that there is something wrong with the use of the flat http://www.xsyzj.cn, such as excessively defragmenting the hard disk, too little memory, so that the application software Hard disk access, etc. 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.
