Once upon a time, it was hard to own a computer. Having a computer was such a luxury no one could easily afford. But, nowadays the number of computer owners are increased dramatically than it was guessed by the inventors. and why not? it is the most important machine today. In the present situation of Tech world, there is no wonder if anyone says that computer is an essential part of a human. Why C is the default drive, instead of A and B?

Though you may be using the computer for many days, most probably there would be many things which were unknown to you. If you are using the computer for many days, then here is a question for you.

Have you ever wondered why the names of drives start from “C”?.


Where had the A and B drive gone?

Here is the answer to the question:

Hard disk drives became standard since 1980. Before hard disk drives, Floppy disk drives were used as the storage devices. Floppy disk drives were the initial storage devices. They came into existence since 1960’s. Floppy disks came in two sizes 5 1/4 ” and 3 1/2″. Those two floppy disk drives were labeled as Local Disk (A) and Local Disk (B). After the invention of Hard disk, a floppy disk of size 8 inch came into existence. Presently Floppy disk drives and Floppy disk drives replaced the floppy disks.

This is the reason behind the labeling of hard drives. As a result, drives other than default drive (C) labeled as D, E etc. DVD drive and USB drive are labeled as F, G and so on.

Though “C” drive comes as the default, you can change it to A or B if you have the administrative rights.
