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.
