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 :-)
