Ever wondered where is the B drive on your Windows PC? I had once thought about it, but didn’t go hunting to know where. Now Anthony digs out the answer:
Later, as computers came with hard drives, the second floppy drive became a useless appendage – the computer equivalent of an appendix. To avoid confusion during the evolutionary window when computers with new hard drives coexisted beside computers with two floppies, the hard drives were given the “C” slot.
Technically speaking, the “computer” isn’t missing the B drive, it’s just that later Microsoft operating systems have omitted it as unnecessary. You can read more about the ins and outs of archaic drive systems at Microsoft Support.
