By using MHDD, if you found an error code "UNC" in several areas (not in groups as a pattern), you can use the option "remapo" = ON.
The function remap = ON is useful to relocate the LBA sector from the damaged area to the table while the damage.
Remap safe to the data recovery from hard drive for not found error codes along the 100 sectors or more. If this occurs, the possibility of data will be corrupted when accessed. To repair the corrupted data, you can use some special utility that is designed for this function.
Here is the complete guide:
1. When the loading process MHDD, press F4, then scan selection box will appear.
2. To activate the remap function: press the down arrow key on your keyboard, to highlight the "remap", then press the space bar to change the option "OFF" to "ON"
3. When finished changing the remap to "ON" press F4 again to remap process running.
4. After the remap process is complete, scan the hard drive again with MHDD, press F4 twice and let the scan run to completion.
5. If no more errors are found, then the bad sectors have all been successfully relocated, and for data recovery from hard drive you can connect the hard drive as slave to another hard drive to copy the data. Or use a cloning software like Media Tools Professional to perform sector to sector cloning to another hard drive healthy.

Recovering files from a corrupted hard drive can be easy if you arm yourself with knowledge, and if the hard drive was only slightly damaged. However, determining the damage of the hard drive can be tricky. So, it is advisable to let the experts check the severity of the damage. This way, you can know if you can repair your hard drive on your own or if you’ll need their help.

Recovery may be required due to physical damage to the storage device or logical damage to the file system that prevents it from being mounted by the host operating system (OS). A wide variety of failures can cause physical damage to storage media. CD-ROMs can have their metallic substrate or dye layer scratched off; hard disks can suffer any of several mechanical failures, such as head crashes and failed motors; tapes can simply break. Data recovery is often performed by specialized commercial services.
