I am having some issue with my working laptop. Yesterday morning when I boot my laptop I observe that my hard disk is not responding as well as not anything is accessible from the hard disk of laptop. I thought that this may be due to any virus or malware so I did a full computer scan using Microsoft security essential. But it does not find any virus or malware. I have very important data of my work and I want to recover it in anyhow. If you have any idea how to recover my hard drive data pleas let me know. Your valuable suggestion would be appreciated. Thank you in advance.
