Friends, in the storage media devices like hard disk, pen drive, and mobile devices, platter and memory sticks are used for data storage. The platter is further divided into sectors. On these sectors, data is read and written by the head. Sometimes hard disk sectors get damaged if the hard disk has been running for too long. This damage occurs in the form of Bad sectors. Once bad sectors are created in the hard disk, these cannot be removed. In this session of logical data recovery training, we will discuss about the Data Recovery procedure of hard disks affected with Bad Sectors.
