How do I know that the disk is failed?

Disk failure can be usually diagnosed when the data present in the disk is not been able to access. Disk failure usually occurs due to voltage fluctuation, fire or water accident or there is an error accidentally made by the user, when the files are accidentally deleted and it leads to boot failure.

Disk failure also occurs because of the bad sectors developed in the hard disk. Hard disk usually works under stress if the stress on the disk increases, though they are resistant of the stress the disk fails.
