If you require recover files from crashed hard drive, refrain from attempting to format or repair the hard drive before recovering the data that needs to be recovered. Determine first if the hard drive is recognized by the computer system and if you are able to browse through some of its folders. If yes, you should start with copying your important files, like documents, pictures, videos, etc. onto another working hard drive. If no, then you might want to try to use some recovery software that would be able to locate any recoverable files on the crashed hard drive. But if you hear any clicking sounds coming from the hard drive or it does not seem to be detected anymore, keep away from further attempts and seek professional help.
