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. Some examples are:
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.
ntwdm (Under Windows 2000 and later) Use Simon Owen's FDRAWCMD
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.
logical Similar to the raw driver, but the resulting disc image
contains tracks laid out in logical filesystem order.
Mainly used for imaging discs in formats (such as ADFS)
where the mapping of tracks to cylinders/heads does not
match the way it's done on the PC.
qm Sydex's CopyQM format (can only be read, not written).
teledisk
Sydex's Teledisk format (can only be read, not written).
-otype TYPE
Determines which driver is to be used to write to the destina‐
tion 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 per‐
mission 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>.
-pcdos 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.
-apricot
Reverse -pcdos, and convert the first sector from a PC-DOS
superblock to an Apricot superblock. Note that this is the
opposite of what this option did in LibDsk 1.1.9 and earlier.
-logical
Rearrange the tracks in the logical order. This option has been
superseded; instead you should use -otype logical to output to a
logically-sectored raw image.
-noformat
Don't format the target disc/image - assume it's in the correct
format already.
