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).
- -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.
