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
Use a list of bad clusters, rather than scanning for bad clusters itself.
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.
Mtools' texinfo doc
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.
