Name¶
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.
Description¶
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 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.
Bugs¶
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 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 texinfo doc. See the
end of this manpage for instructions how to view the texinfo doc.

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.
