Hard disk drives changed from 1980 to standard. Prior to this, hard disk drives, floppy disk drives were used as storage devices. Floppy disk drives were the first storage devices. They came into being from the 1960s The floppy disk was available 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 hard disk innovation, the size 8-inch floppy disk was introduced. Currently, floppy disk drive and floppy disk drive changed floppy disk. The only reason behind the labeling of the hard drive. As a result, in addition to the default drive (C) labeled as D, E etc. drive DVD drive and USB drive are labeled as F, G and further.
