External Hard Disk Drive Powered By Docstoc
					External hard disk drive are the drives which remain outside the CPU.
They are connected to the system via USB cable. The internal components
of an external hard disk drive are similar to the hard drives which are
found inside the system. They also have the platters and moving heads
like in the traditional hard disk drives. They are found in different
sizes like the 2.5 inch and 3.5 inch drives. They also support plug and
play, so we have to just connect the USB cable to the USB port of the
system. And the system automatically recognises the external hard drive
as a storage device and asigns a drive letter to it. In some cases we
will have to install the device drivers which comes with the external
hard drive package.
