xdfcopy




Note
       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 represen-
       tation  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 doc.

       *      To generate a printable copy from the texinfo doc, run the  fol-
              lowing commands:

                     ./configure; make dvi; dvips fdutils.dvi



       *      To generate a HTML copy,  run:

                     ./configure; make html

              A       pre-made       HTML      can      be      found      at:
              `http://www.tux.org/pub/knaff/fdutils'

       *      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.

Description
          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 Den-
       sity 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

       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 ignored

       -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.
