DESCRIPTION
Dsktrans copies floppy discs or images,
optionally converting image types. This is a high-level copy which
assumes that the disc has a straightforward geometry; all the
tracks are assumed to have the same layout of sectors, and
interleave is not preserved. See dskdump(1)
for a slower but more accurate copy which may preserve more of
these details.
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.
- -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.
- -md3
- Defeat MicroDesign 3 copy protection. Note that this does not
make dsktrans a circumvention device, since the authors of
MicroDesign have placed it in the public domain and given
permission for the copy-protection to be reverse engineered; I
posted their original press release to USENET as <1008359853.26849.0.nnrp-13.c2de7091@news.demon.co.uk>.
- -apricot
- Convert the first sector from an Apricot superblock to a PC-DOS
superblock. This allows Apricot-format discs to be imaged as files
(with the output image type as raw) and then loopback-mounted under
Linux.
- -logical
- Rearrange the tracks in the logical order. This option is
useful when the output image type is raw and you're reading a disc
with a non-IBM track layout, such as 144FEAT 1440K or ADFS 'L'.
- -noformat
- Don't format the target disc/image - assume it's in the correct
format already.
