Not correct. You really low-level format almost all hard-sectored media,
including floppies, because most still contain a sector header that
includes information like track and sector number before the actual data.
And the RK05 makes no exception. It (or better, the controller) actually
reads the sector header before writing a sector to ensure that the head is
on the correct track.
So in that respect it would be worthy to know if the
packs on eBay are
12 or 16 sectored? 12 sectored ones are relative more common than the
16 sectored ones AFAIK.
Well, I also have some 24 sector packs (e.g. HP 7900), a lot of 4 sector
packs (IBM 2315), and soft-sectored packs for HP 7905/7906. They all look
the same, but differ in recording and/or track density.
