    Why is there no A or B partition


    Someone asked me today why the partition numbering always starts with C and why there are no A or B partitions. I did not know the answer. Does anybody know?

    Letters A and B are reserved for Floppy Drives. C to Z are reserved for Hard Disks, CD, DVD, TAPE and Other Magnetic Drives and Disks.

    They were reserved for floppy drives, but if you format a partition in W7 it will give you the option to name it A or B. I was surprized myself.

    Possibly due to past practice of reserving A & B for floppy drives? I know you can still set it later... I made my back-up HDD drive B:

    Thanks guys. That was simple. I was not around PCs during the floppy times so I did not know that. One never stops learning.
