Oh that's funny, I am also old enough, but I'd have sworn I used floppy disks that had "HDD" on them. I think you're right though. All the pics are showing "2HD" and the more rare "3HD". There were disks with "High Density Diskette" printed on them, and initialisms "HD" and "DD" (double density). But I can't find any examples of HDD outside of hard disks.
