       mbadblocks - tests a floppy disk, and marks the bad blocks in the FAT

Note of warning
       This manpage has been automatically generated from mtools's texinfo documentation, and may
       not be entirely accurate or complete.  See the end of this man page for details.

       The mbadblocks command is used to mark some clusters on an MS-DOS filesystem bad.  It  has
       the following syntax:

       mbadblocks [-s sectorlist|-c clusterlist|-w] drive:

       If  no  command	line  flags  are  supplied, Mbadblocks scans an MS-DOS filesystem for bad
       blocks by simply trying to read them and flag them if read  fails.  All	blocks	that  are
       unused are scanned, and if detected bad are marked as such in the FAT.

       This  command  is  intended to be used right after mformat.  It is not intended to salvage
       data from bad disks.

Command line options
       c file
	      Use a list of bad clusters, rather than scanning for bad clusters itself.

       s file
	      Use a list of bad sectors (counted from beginning of filesystem), rather than  try-
	      ing for bad clusters itself.

       w      Write  a	random pattern to each cluster, then read it back and flag cluster as bad
	      if mismatch. Only free clusters are tested in such a way, so any file data is  pre-

       Mbadblocks  should  (but doesn't yet :-( ) also try to salvage bad blocks which are in use
       by reading them repeatedly, and then mark them bad.

Viewing the texi doc
       This manpage has been automatically generated from mtools's  texinfo  documentation.  How-
       ever,  this  process is only approximative, and some items, such as crossreferences, foot-
       notes and indices are lost in this translation  process.   Indeed,  these  items  have  no
       appropriate  representation in the manpage format.  Moreover, not all information has been
       translated into the manpage version.  Thus I strongly advise you to use the original  tex-
       info doc.  See the end of this manpage for instructions how to view the texinfo doc.

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

		     ./configure; make dvi; dvips mtools.dvi

       *      To generate a html copy,	run:

		     ./configure; make html

       A premade html can be found at `http://www.gnu.org/software/mtools/manual/mtools.html'

       *      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.
