Greetings & Merry Christmas to all; I need to support a disk format that has been built into the linux driver floppy.c since about 2.5.47 or so. That is the ability to format and use a floppy disk format whose LSN0 is track 0, sector 0. Unforch, attempting to do a setfdprm on a format description in mediaprm that ends in the string 'zero-based' is such a shock to setfdprm that it bails out with an error, before it reads the rest of the mediaprm file. Are there patches for fdutils that allow it to work with those zero-based disk formats? Without this, I cannot set for that condition, and an attempted dd if=/dev/fd0u720 fails with an i/o error without reading a single byte of an 80 track, double-sided, double-density formatted on a color computer running os9 system disk. Thanks. -- Cheers, Gene "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo. Please use in that order." -Ed Howdershelt (Author) But like the Good Book says...
