| .SH Description |
| .PP |
| The \fR\&\f(CWmbadblocks\fR command is used to mark some clusters on an |
| MS-DOS filesystem bad. It has the following syntax: |
| .PP |
| \&\fR\&\f(CWmbadblocks\fR [\fR\&\f(CW-s\fR \fIsectorlist\fR|\fR\&\f(CW-c\fR \fIclusterlist\fR|-w] \fIdrive\fR\fR\&\f(CW:\fR |
| .PP |
| If no command line flags are supplied, \fR\&\f(CWMbadblocks\fR 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. |
| .PP |
| This command is intended to be used right after \fR\&\f(CWmformat\fR. It is |
| not intended to salvage data from bad disks. |
| .PP |
| .SH Command\ line\ options |
| .TP |
| \&\fR\&\f(CWc\ \fIfile\fR\&\f(CW\fR\ |
| Use a list of bad clusters, rather than scanning for bad clusters |
| itself. |
| .TP |
| \&\fR\&\f(CWs\ \fIfile\fR\&\f(CW\fR\ |
| Use a list of bad sectors (counted from beginning of filesystem), |
| rather than trying for bad clusters itself. |
| .TP |
| \&\fR\&\f(CWw\fR\ |
| 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. |
| .PP |
| .SH Bugs |
| \&\fR\&\f(CWMbadblocks\fR should (but doesn't yet :-( ) also try to salvage bad |
| blocks which are in use by reading them repeatedly, and then mark them |
| bad. |

| .SH 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. |

| 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. |
