mbadblocks General Commands Manual mbadblocks

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 clus‐
ters itself.

s file
Use a list of bad sectors (counted from beginning of filesys‐
tem), rather than trying 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 preserved.

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. However, this process is only approximative, and some
items, such as crossreferences, footnotes and indices are lost in this
translation process. Indeed, these items have no appropriate represen‐
tation in the manpage format. Moreover, not all information has been
translated into the manpage version. Thus I strongly advise you to use
the original texinfo 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 fol‐
lowing commands:

./configure; make dvi; dvips mtools.dvi

* To generate a html copy, run:

./configure; make html

A premade html can be found at `‐

* To generate an info copy (browsable using emacs’ info mode),

./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.
