Ah yes, C64 floppy drive “headbanging”.
IIRC this is because rather than ship a design with a limit switch or any position sensing at all, the drive software just rapidly slaps the read head home a bunch of times to ensure it’s properly aligned with track zero. I have a hard time believing this was to reduce part count, because the drive itself is a whole-ass 6502 computer; the sale price also reflected that. Instead, I think it’s a software fix for a “sometimes an issue” hardware problem.

One starts to get the impression that they should just have the archeologists dig the tunnel in the first place, and budget the project like one big find.
