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.

Zeg NEE tegen de 'slimme' meter.
Is it possible to do some kind of "low
level" format (whatever that
means) using an rk05? /P
They're hard-sectored. Every time you write to a sector it does a
low-level format of the sector. Anything that will write to all the
sectors of the pack will effectively format it.
What you can't do that easily is change a 12-sector pack (e.g., for
PDP-11) into a 16-sector pack (e.g., for PDP-8), or any other such
sectoring changes. The sector marks are physical slots in the hub
ridge. Some of us have speculated that a person could contrive a
circuit with a PLL to fake the sector marks electronically, and ignore
the physical ones, but I haven't heard of it actually being done.
