How to fix a bad track on a laptop hard drive

Hard Drive In addition to the quality of the hard drive itself and the reasons for aging, largely due to improper use of the usual cause. Computer illegal shutdown, the hard drive is still in the state of operation is forced to quit, static electricity or temperature is too high, a long time did not clean up the hard disk of the ash may cause the hard drive to upload some of the data sector has been bad, that is, the hard drive appears bad. So, how does the laptop hard drive have a bad way to fix it?
Before looking for a way to repair the bad path of a computer hard drive, first of all we need to understand that the hard drive bad path according to its nature can be divided into logical bad and physical bad channel two.
In general, the reason the hard drive generates a logical bad path may be that some genuine software writes information to certain sectors of the hard disk. Other software does not have access to this sector, in which case the hard drive detection tool will also consider the sector to have a bad path, which does not need to be repaired and is rarely used by software today. There is another situation where improper use is the result. For example, the hard drive is unexpectedly restarted when it reads data. It is possible to generate a logical bad path, which can even lead to a physical bad path, at which time the hard disk is scanned using the WINDNWS's own diskette tool, and the error is automatically repaired. Logical Bad DAO can also be repaired using professional software.
The physical bad word refers to the problem of the magnetic medium of the hard disk disc itself. Such faults cannot be repaired by means of software. Because with a variety of tools repeatedly scanning, is the hard disk's physical bad area to enforce multiple reads and writes, will inevitably become a lot of bad way, and then spread, the right way is to use the following method to decisively put the place has been broken to separate open. Generally, when the hard drive is determined to have bad lanes. It is not certain that the bad path is a logical or physical damage. In order to prevent misoperation on the hard disk two damage, so everyone except in peacetime use to pay more attention to the protection of hard disk, once found hard drive bad data loss, do not operate freely, contact Shanghai Day Shield Data recovery experts to help you recover data safely.
