Often enough, files just corrupt, without an underlying disk error. However, if there should be such an error, the hard disk needs to be replaced.

So-called cleaner software is usually superfluous, though. Some of these appllications cause harm rather than fix anything (for example because they delete registry entries that are required for an application to work properly).
