       xdfcopy - copy and format XDF disks in Linux


       This  manpage  has  been  automatically  generated  from  fdutils's texinfo documentation.
       However, this process is only approximative, and some  items,  such  as  cross-references,
       footnotes  and  indices are lost in this translation process.  Indeed, these items have no
       appropriate representation in the manpage format.  Moreover, only the  items  specific  to
       each  command  have  been  translated,  and the general information about fdutils has been
       dropped in the manpage version.  Thus I strongly advise you to use  the  original  texinfo

       *      To generate a printable copy from the texinfo doc, run the following commands:

                     ./configure; make dvi; dvips fdutils.dvi

       *      To generate a HTML copy,  run:

                     ./configure; make html

              A pre-made HTML can be found at: `'

       *      To generate an info copy (browsable using emacs' info mode), run:

                     ./configure; make info

       The  texinfo  doc  looks most pretty when printed or as HTML.  Indeed, in the info version
       certain examples are difficult to read due to the quoting conventions used in info.


          xdfcopy [-format-id] [-d] [-n] [-h head-skew] [-t cylinder-skew] [-T
          end-cylinder] [source] target

       Xdfcopy is a utility to copy and format XDF disks. XDF  (eXtended  Density  Format)  is  a
       format  used  by  OS/2  which  can hold 1840KB of data (on a 3 1/2 high density disk). Its
       advantage over 2m formats is that it is faster: 38KB/s. Because  of  this  fast  speed,  I
       extended  the XDF standard to higher capacities (1992KB) with a transfer rate of 45KB/s. I
       called the new formats XXDF.

       This program works best with kernels newer than 2.0.0.

       If both source and target are given, xdfcopy copies the disk image  from  file  to  floppy
       disk or vice-versa. When copying to a floppy disk, the disk is first formatted, unless the
       -n option is given.

       If no source is given, the target is only formatted. In this case, the target  must  be  a
       floppy drive.


   Selecting a format
       Formats are selected by the format_id. The following formats are understood:

       0      Formats a 5 1/4 XDF disk (1520 KB, 45.6 KB/s).

       1      Formats a 3 1/2 high density XDF disk (1840 KB, 38.3 KB/s).

       2      Formats a 3 1/2 extra density XDF disk (3680 KB, 102 KB/s)

       3      Formats a 3 1/2 high density XXDF disk (1920 KB, 45 KB/s)

       4      Formats a 3 1/2 extra density XXDF disk (3840 KB, 90 KB/s)

Misc options

       -D dosdrive
              Describes  the  DOS  drive  letter  for mformat. If this option is given, an MS-DOS
              filesystem is automatically installed on the disk after  the  low-level  format  is
              complete.  In  order for this to work, the drive has to be configured to accept the
              23x2x80 geometry in your /etc/mtools or your ~/.mtoolsrc file. Moreover, this  only
              works with a version of mtools that is more recent than 3.0.

              Example of a working mtoolsrc line:

                 A /dev/fd0  0  0 0  0

              Examples of a non-working mtoolsrc line:

                 A /dev/fd0 12 80 2 18

       -n     Don't format the disk before copying the disk image to the disk.

Options for power users

       -t cylinder skew
              Uses  a  different track skew than the default (14). For more details on skews, see
              section  superformat. In this version of xdfcopy, the -t parameter is ignored.

       -h head skew
              Uses a different head skew than the default (0) In this version, this parameter  is

       -d     Debugging.  For  each  read  or  write  operation, the time it took to complete the
              operation is printed (in milliseconds). This can be used to optimize the skews.

       -T end-cylinders
              Tells how many cylinders to format.  With the XXDF formats, it is actually possible
              to  format  up  to  83 cylinders, yielding a format of up to 1992KB on a 3 1/2 high
              density disk.
