For those too young to remember, the A:\ drive was for the hard 3" floppy disks and B:\ drive was for the soft 5.25" floppy disks. The C:\ drive was for the new HDDs that came out, and for whatever reason the C:\ drive became the standard after that.

A was the first floppy drive and B the second floppy drive (in dos and cp/m). The type of drive was irrelevant.
FWIW they were the other way around on my system. The order of A:\ vs B:\ depended on their order on the cable (“first” and “second”), not type.
