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 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 doc.

*   

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: ∞http://www.tux.org/pub/knaff/fdutilsIntegral

*   

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 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.

Options

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.
