Don't 8 inch drives have 77 tracks?
YES. Although 8" "emulation" sometimes cheats and uses 80.And some users with drives without a physical stop tried to squeeze a few more tracks (and 41,42 on 360K) The inability to read those "extra" tracks on a different drive didn't show up until the disk was nearly full (inner tracks are normally last allocated)
SA400 was 35 track (TRS80, and SA390 Apple) Q: how many tracks are the HP formats?
