NAME
     dskscan - Scan a floppy disc for sector headers

SYNOPSIS
     dskscan  [-type  TYPE]  [-side  SIDE]  [-comp COMP] [-dstep] [-retry COUNT]
     [-format FMT] [-first CYLINDER] [-last CYLINDER] [-xml] DISKIMAGE

DESCRIPTION
     Dskscan scans a floppy disc (or a disc image) and prints any sector headers
     that it finds. It does not attempt to read the sectors.

OPTIONS
     -type TYPE
	    Determines which driver is to be used to read from the disc.

	    auto    Select according to the disc image file.  This  is	the  de-
		    fault.

	    dsk     Use the DSK (CPCEmu format) image driver.

	    edsk    Use the extended version of the DSK format.

	    floppy  Use the floppy driver.

	    myz80   Use the hard disk (MYZ80 format) image driver.  (This format
		    cannot be autodetected.)

	    cfi     Use  the CFI (DOS fdcopy format) image driver.  (This format
		    cannot be autodetected.)

	    apridisk
		    Use the ApriDisk image driver (from the utility of the  same
		    name).  (This format cannot be autodetected.)

	    raw     Use the raw driver.

     -comp COMP
	    Select  the  compression  method  used on the source disc image file
	    (has no effect when reading a floppy disc).

	    auto    Detect from the first few bytes of the file. This is the de-
		    fault.

	    sq	    Huffman coded (SQ / USQ).

	    gz	    Gzipped (gzip / gunzip).

	    bz2     Burrows-Wheeler compressed (bzip2 / bunzip2).

     -side SIDE
	    Determines which side (0 or 1) of the source disc is to be	scanned.
	    If this option is not present both sides will be scanned.

     -dstep
	    Double-step  the source drive (used to read 360k discs in 1.2Mb dri-
	    ves). Only supported by the Linux floppy driver.

     -retry COUNT
	    Set the number of times to attempt a read/write/format  in	case  of
	    error.

     -format FMT
	    Do	not autodetect the disc format; use the named format. The format
	    need only be an approximation to the actual format used by the disc.

     -first CYL
	    Start scanning at the specified cylinder.

     -last CYL
	    Scan up to and including the specified cylinder.

     -xml   Output results as XML rather than as  text;  if  you  are  launching
	    dskscan  from another program which then parses what dskscan prints,
	    this may be easier for it to cope with.
