Similar situation on the 1581 disks. The directory format and file structures
are different. READ81S makes BIOS calls and essentially acts like the 1581's
higher level programming.

If by 3.5" drives you mean the 1581, they are intelligent devices. I've
understood intelligent to *definitely* mean they have their own CPU, which
the 1581's (and all other Commodore serial devices) do.
