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.
