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.
