Use at your own risk. + +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). + +Please send bug reports, comments, flames, etc. to +almesber@nessie.cs.id.ethz.ch or almesber@bernina.ethz.ch + +- Werner + +FAT32 and LFN support +===================== + +I've finally implemented some of the new features of MS-DOS +filesystems: FAT32 and long filenames. + +FAT32 is automatically detected and of course the different FAT +structure is handled. (Internally many changes were needed, so 32 bit +variables for all cluster numbers and 64 bit vars for offsets inside +the filesystem.) New checks for FAT32 are most notably on the backup +boot sector and the new info sector. Also the possibility that the +root directory resides in a cluster chain (instead of in a static +area) on FAT32 is handled. + +dosfscheck also knows about VFAT long filenames now. It parses those +names and uses them in listings etc. when available. There are also +some checks on the (cruel) structure of how LFNs are stored and some +attempts to fix problems. + +- Roman <roman@hodek.net> + +BTW, version 2 isn't ALPHA anymore :-) |
