Why hard disk partitions are named as C,D,E,F and not as A,B,C,D?

Answer 1

It is because the way computers were originally set up, they needed to have the floppy disks as the first couple of drive letters.

Drive letters A and B are reserved for floppy disks because older computers needed to boot off floppies first.

Then once hard drives came along, the main hard drive has the C drive letter reserved as well.

So the only available other letters are D, E, F, G, so on and so forth.

Answer 2

ok her it is...

People are brain washed into thinking MS was out in (1970's) it was NOT, there was many DOS systems out even then Tandy Dos, (Radio Shack) DR Dos (IBM), Sinclare Dos. MS Dos only came into being in the 80"s. each computer had only 64kb off memory.

When computers first came out, running under DOS (disk operating system) the first drive was all ways the floppy disk, (A) drive, in those days there was no hard drives, each floppy disk where 5 1/4 floppy disks that held 320 kb, this held the bootup commands. and programs

A drive was the boot drive, and drive B (floppy) was the disk that held all the data on,

then came the hard drives that started at around 50 megabytes, and eventually got bigger and bigger, which was the C drive then came the time you could put two hard drivers in a computer, the second hard drive became D drive, then came other types of drives tape drives, zip drives, cd drives so the drive letters increased from A,B to all the letters of the alphabet A to Z,

Answer 3

Because Back in the day when MS-DOS (Microsoft Disk Operating System) to open a file there was no hard drive there were the floppy disks so now computers boot windows using (and yes its true) MS-DOS so there you have it P.S. A: and B: were the floppy disks and when they started usuing Hard drives they didnt want to change it so they started at C:

Answer 4

Because A & B are already allocated for use by a different drive. In Windows the A: drive is your 3.5 floppy drive. The B: drive is a second floppy drive. C: is your Windows partition. D is either another hard drive paritition or a CD/DVD drive.

Answer 5

Simply, because the drive letter A and B were meant for the floppy drive or removal storage drive. So the permanent disk drive starts with C

Answer 6

Before there were such things as hard disks, you had a floppy drive on your computer that you used to run nearly all programs.
If you were lucky, or rich, you had two floppy drives.
Naturally these were drives A and B.
Ever since those days, A and B have been reserved for floppy drives.

Answer 7

Thats because A, B were reserved for the floppy disk drives. Thats the old and new style floppy drives. From there its for the rest, hard drive, cd rom and etc.

Answer 8

Because in the old days, MS-DOS reserved A and B for floppy drives.

Today, these "legacy devices" are still used on older PCs, so Windows still supports them..

Answer 9

A and B are reserved for floppy drives (thanks to computer's evolutionary history), the rest(c,d,e..) can be changed if u want to during windows setup or using third party softwares like partition magic .

Answer 10

A: and B: were reserved for floppy drives. My current PC doesn't even have a floppy drive.
