NAME

dskdump - Sector-level copy from one floppy or image file to another

SYNOPSIS

dskdump [-itype TYPE] [-otype TYPE] [-iside SIDE] [-oside SIDE] [-icomp COMP] [-ocomp COMP] [-idstep] [-odstep] [-retry COUNT] [-format FMT] [-first CYLINDER] [-last CYLINDER] INPUT-IMAGE OUTPUT-IMAGE

DESCRIPTION

Dskdump copies floppy discs or images, optionally converting image types. Unlike dsktrans(1), dskdump can handle discs with different numbers or sizes of sector on different tracks.

OPTIONS

-itype TYPE: Determines which driver is to be used to read from the source 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.

-otype TYPE: Determines which driver is to be used to write to the destination disc. The drivers are as for -itype.
-icomp 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).

-ocomp COMP: Select the compression to be used on output. Compression methods are as for -icomp, except that bz2 cannot be used.
-iside SIDE: Determines which side (0 or 1) of the source disc is to be read from.
-oside SIDE: Determines which side (0 or 1) of the destination disc is to be written to.
-idstep: Double-step the source drive (used to read 360k discs in 1.2Mb drives). Only supported by the Linux floppy driver.
-odstep: Double-step the destination drive (used to write 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. dskdump does not make extensive use of the disc format; it is chiefly used to provide a guess at the number of tracks to dump.
-first CYL: Start copying at the specified cylinder. Cylinders prior to this will not be formatted or written.
-last CYL: Copy up to and including the specified cylinder.
-odstep: Double-step the destination drive (used to write 360k discs in 1.2Mb drives). Only supported by the Linux floppy driver.
