The Hard Drive's Driver:

The driver of the external disk is very similar to, the internal HDD on a computer, which consists of a rotating platter with a magnetic surface that rapidly stores digitally encoded data. It also provides the means of communication between the drive and the computer to which it is connected. It functions by giving the hard drive's serial/model number as well as physical information (sectors, heads, and the storage capacity) to the operating system so that it can recognize it.
