Hard drive for a long time on this kind of problems that may arise, while the hard disk "bad sectors" such as problem identification, one of the most common problems. In addition to the hard disk itself quality reasons, there is usually pay attention to maintenance hard disk, can also cause hard disk damage. Hard disk damage is divided into logical bad sectors and physical bad two, the former is soft bad sectors, usually due to improper operation or use of the software, you can use software to repair; the latter is a real physical bad sectors, it shows generating a physical damage on the hard disk track can only be solved by changing the use of the hard disk partition or sectors. So in the course of the hard disk determines how hard is bad sectors or bad sectors it coming? The following phenomena occur if the hard disk, then the time to pay attention whether the hard disk has bad sectors;
1. When reading a file or run a program, the system repeatedly read the disk and error, suggesting that information such as file corruption, or take a long time to run successfully; sometimes even a blue screen and so on.
2. Run the hard disk voice suddenly increased from the normal friction sound into a strange sound.
3. The system does not start normally under exclusion of virus infection, the emergence of "Sector not found" or "General error in reading drive C" contains.
4. Format the hard disk, to a certain progress at a standstill, the last error, can not be completed.
5. each time the system is turned on will automatically run Scandisk scan disk error.
6. implementation Fdisk the hard drive, to a certain schedule will be repeated forward and backwards or stagnating.
We need to take extra care if your hard disk above scenario, then your hard drive has begun to appear bad sectors. Then the hard disk of course we should be how to reduce the incidence of hard disk bad sectors, improve the life of the hard drive it? Here are some suggestions.
1. kept clean to prevent static electricity
Although a sealing member is hard, but if the environment may cause excessive dust or hard contact failure, the local short circuit or dust into the internal dish peer failures. Similarly, when you are working hard to pay attention to prevent static electricity, static electricity is invisible killer hard drive can easily lead to bad sectors hard disk, so be sure to discharge his hands and metal tools on other metal precursors removable hard disk, hard disk and avoid the electric plug. Hand can easily lift the back of the drive circuit board, when the hard disk should be seized by hand on both sides of the hard disk, to avoid contact with the circuit board static.
2. gently correct shutdown
Avoid hard in the course of collision with other solid objects, gently. Correct computer shutdown can reduce the harm caused by momentary power pulse on the hard disk. Often abnormal shutdown would hurt the hard disk.
3. Finishing the regular and timely maintenance
Hard disk using a long time will produce a large number of file fragments, too much fragmentation can cause slow implementation of the program and start to develop the habit of timely clean-up. When a small amount of hard disk has bad sectors, the need for repeated retry the head when reading the data on the bad sectors, can easily result in proliferation of bad sectors, so it should be timely maintenance and avoid bad sectors to expand.
4. Other Considerations
Temperature and humidity also have an impact on the hard disk, maintaining, in use, preferably 20-25 ° C, humidity 45% -65% is appropriate. Also try to avoid hard disk to magnetic fields, such as stereos, speakers, click, radio, cell phone, etc., in order to avoid the data in the hard disk error due to magnetization.
