坏道修复（mhdd） Summary Due to the hard disk with magnetic media to store data, after a long time of use or improper use, there will be some problems, also known as bad, but this may be the wrong software sectors, there may be a hard disk itself hardware failure, but not to say that the hard disk has after the bad sectors will be scrapped, in fact the treatment properly, we can make the hard disk recovery, at least you can let the hard prolong life. [edit this paragraph] categories The hard disk has bad sectors in addition to the hard disk itself quality and aging reasons, and largely because it is usually caused by improper use. According to the nature of the hard disk can be divided into two kinds of physical and logical bad sectors, simple, logical defects is due to some software or improper use of bad sectors, it can use the software to repair, which is a magnetic medium physical bad sectors hard disk itself problems, such as disk physical damage, this kind of commonly used software fault can not repair the mistake. [edit this paragraph] Note If your hard drive once these phenomena, you should pay attention to whether there have been bad sectors hard disk: (1) in reading a file or running a program, the hard disk repeatedly read and error, prompt file damage and other information, or it takes a long time to succeed; sometimes there will be a blue screen and so on; (2) the sound of the hard disk suddenly changed from the normal friction sound to the strange sound; (3) in the case of excluding virus infection, the system can not start normally, and there is Sector not found or General error in reading drive C and other prompt information; (4) Format hard disk, to a certain progress stopped, and finally reported wrong, can not be completed; (5) the Scandisk scan disk error is automatically run every time the system is turned on; (6) when a FDISK is executed on a hard disk, a progress will be repeated; (7) start not through the hard disk boot, floppy disks can start to h
