Suddenly, My hard disk is not working. While booting, It gives failed command: READ DMA
and status: { DRDY }
error. So, I booted the system with live CD and tried to mount the hard disk. It gives the following error.

Is there any way to fix these errors?
Atleast, How to recover the data from the hard drive? Because, I have more important data in that hard disk.
What does these error means?
