Hallo Spiro, > The 1541 and the 2031 layout differ in the length of bytes > between end of header and start of sync of the data. There is nothing between end of header and start of sync of the data: the bytes between the end of the header and the start of the data ARE the syncbytes. The header and all further syncbytes are only written once: when formatting a disk. The syncbytes trigger the hardware in such a way that it doesn't matter if there are 2, 3, 4 or even more syncbytes in a row. The minimum is 11 1-bits in a row IIRC. The drive starts reading/writing the moment it detects the first 0-bit. For more tecnical details please see my site at Documents, chapter 1541. -- ___ / __|__ / / |_/ Groetjes, Ruud \ \__|_\ \___| http://Ruud.C64.org Message was sent through the cbm-hackers mailing list
