dosfstools contains that following utilities: dosfsck, dosfslabel and mkdosfs.
dosfsck is the Linux equivalent of PC/MS-DOS' CHKDSK. It checks the consistency of PC/MS-DOS file systems and optionally tries to repair them. The tests dosfsck performs are described in the man page.
dosfsck needs header files from dosfs.9 (or later) to compile.
Before using dosfsck to repair a file system that contains data of any value, you should verify that dosfsck is able to correct all reported errors. (Except fatal errors and those reported as unfixable, of course.) In order to do this, run it with the -V option, e.g.
dosfsck -V /dev/sda1 (automatic check)
or
dosfsck -V -r /dev/sda1 (interactive check and repair)
dosfsck will perform two passes: in the first pass, inconsistencies are detected and a list of changes to correct the problems is generated. In the second pass, those changes are applied whenever dosfsck reads data from disk. Hence no fixable errors should be reported in the second pass if the first pass was successful.
Please notify the author if fixable errors are reported in the second pass.
After verifying that dosfsck appears to be able to perform the desired operations, either confirm that you want the changes to be performed (if dosfsck was started with -r) or re-run dosfsck with the -a option (if it was started without -r).
Users of the following distributions (alphabetically sorted) can install dosfstools 3 with the regular package management tools of their distribution:
* Arch
