5.25 Drive Nibbler Question



5.25 Drive Nibble Question

    I understand that all copy-protected software and non-copy-protected
software are stored in 4-4 encoded format.  Are they always 384 bytes
(normal 256 bytes) in the order of bit from the beginning through the end.
    Does copy-protected software change the sector order within 256 bytes,
but it never change 384 bytes?  For example, GCR software is supposed to
read 256 bytes on track 2 sector 5, but it only reads 128 bytes in one place
and another 128 bytes in place such as half track or sector, but GCR
software has ability to read all 384 bytes before it can become valid in 256
bytes.
    Do you know what I am talking about?

    Is it true that Copy II Plus CAN COPY 384 bytes in nibbles from track 0
sector 0 through track 22 sector 15 from the source to the destination, but
without reading 384 bytes, it will not be possible to copy 256 bytes?
