Hard disks are larger, faster, and more reliable storage devices as compared to floppy disks. Hard disks have changed in their shape, size, and storage capacity ever since their introduction with the IBM-compatible PCs.
Today, the standard hard disk can store and retrieve enormous data much faster than the hard disks used a decade ago.
A computer system uses hard disks as the primary storage device for storing the operating system, applications, and data. Typically, a hard drive failure is the most traumatic event that can occur on a computer. If the hard disk crashes and the data are not backed up, the data is lost forever.
Currently, the two most widely used hard disk technologies are IDE and SCSI.
This tutorial covers the various IDE and SCSI options and configurations.
