No the header is in the original file, not on the disk it is added by the disk read program
I think the sector headers are in the logical order, and so could just be stripped off to give a .raw format
Otherwise crate an array of sectors eg 35 by 2 by 10 and read the header, allocate it to the appropriate array index and down the file.
If you want you can check the correct order in the headers as you go.
