- dosfsck, version 1
- ==================
-
- WARNING: This is ALPHA test software. 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

- 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.

- BTW, version 2 isn't ALPHA anymore :-)
