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.
