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.
