But did yuo found code to check that track 1 has an extra sector without data (ID segment without DATA segment) with weir content.
This can probably be done by using read address command (even though we have 7 sync sequence instead of 3) or by doing a read track and looking for 7 A1 followed by FF
No code for testing that weird seq. It may be just some glitch of multiplicator machine, or in purpose to confuse copy HW .
