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 default.

              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 default.

              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  drives).  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.
