xdfcopy

NAME

       xdfcopy - Program to copy and format Xdf disks in Linux

SYNOPSIS

       xdfcopy [-Ddos-drive] [-d] [-n] [-hhead_skew]
       [-ttrack_skew] [source] target

DESCRIPTION

       Xdfcopy is a utility to copy and format Xdf disks. Xdf  is
       a  format  used  by OS/2 which can hold 1756k of data. Its
       advantage over 2m formats is that it's access is faster.

       This program only works with kernels  newer  than  1.3.40.
       (If  there's  sufficient  interest, I'll include a program
       working with older kernels in the next release)

       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, un-
       less the -n option is given.

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

OPTIONS

       -Ddosdrive
              Describes the DOS drive letter for mformat. If this
              option  is  given, an msdos filesystem is automati-
              cally 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 2.5.4.
               Example of working mtoolsrc lines:
                A /dev/fd0  0  0 0  0
                A /dev/fd0 12 80 2 23

              The former is preferable, as it matches any format.
              The latter matches only 23 sector formats (such  as
              Xdf and certain 2m formats).

               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

       -ttrack skew
              Uses a different track skew than the default  (14).
              For more details on skews, see the superformat man-
              page.


       -hhead skew
              Uses a different head skew than the default (0)


       -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.
