As far as I know, that is not the case. Unpatched DOS 3.3 can store only
140K since it supports only 5.25 inch disks. Patched DOS 3.3 (with
another hardware driver I mean) can store up to 400KB if the medium is
big enough, but not 16MB.
New ProDOS introduced a new
high level format that stores up to 32MB in size.
Yes.
Does it mean 512 bytes per
sector or double "65535" ? If not that, how does it make 32MB in size?
The "16 sector" low level format has nothing to do with any 16MB DOS
maximum; such a 16MB DOS maximum does not exist at all.
ProDOS uses the same 16-sector low level format as DOS, *if and only if*
you use ProDOS on a 5.25 inch disk. On other disks (hard disks, 3.5 inch
floppies, CD-ROMs, etc.) it does not use that format.
I don't really understand that question, though. Could you reword it?
