Hard-Disk Drive
A hard-disk drive is used to read information from, and write
information to, a permanent, non-removable disk mounted inside the
system unit.
The hard disk has a large storage capacity, usually tens of
megabytes. The computer also finds information faster on the hard
disk than on a diskette.

indicator light which blinks when the drive is reading from, or
writing to, the hard disk.
Note: Never turn the system off when a read/write indicator blinks.
