How do I recover data from drive having BAD sectors?

The best way to recover data from drives having bad sector, is to clone the drive or to create disk image of the drive and then to process cloned drive or created image, this eventually helps in ignoring the bad sectors and avoids continuous read attempts directly on the disk in real-time situation.

The less number of read attempts ensures no further increase in bad sectors and no further loss of data.
