Comment on Ask HN: What software do you miss that no longer runs on modern hardware?parent

Hmm. Sure about that? There may be a mixup in terminology. The mass storage device class is what USB sticks for example also uses, and that supports sector level access. In fact that's what's used, as the OS contains the file system implementation, not the device itself.

This is in contrast to the "Media Transfer Protocol" that a lot of smartphones use, for example, where the filesystem implementation is abstracted away in the device, and you essentially have commands to transfer files.

But there were some ways to effectively redefine the sectors themselves, e.g. formatting floppy disks with higher (or lower) capacity, independently of the file system that would sit on top (you'd still access sectors, but now there would be more or less of them). I don't know if USB floppy drivers still support that. And I also don't know whether Windows started to prevent sector-level access.
