1.2. Introduction 

Hard disks make normally the following types of troubles: 

 Some sectors of the hard disk become incapable of storing and retrieving data. To recover from this problem any disk scanning software can be used. Scandisk, Norton Disk Doctor etc. are this kind of software. They mark these sectors as bad sectors and then the programs do not use them for reading and writing. 

 The hard disk is not installed properly. This problem can be recovered by reinstalling the hard disk.  The hard disk is crashed. It is normally not recoverable. The solution is to leave the old and buy a new hard disk and install it. 

So when any body knows hard disk installation he can solve the common hard disk problems. 

To run a hard disk in your computer, the hard disk should be connected to your computer by proper cabling and configured properly. It is called hard disk installation. There are different types of hard disks with different interfaces. Most of the hard disks available today are with IDE interface. So in this lesson we have specially discussed how to install an IDE hard disk.
