ISJ utility  -  Work with JFS superblock


Introduction
------------

It's better to read "jfs_basic_info.txt" before reading
this document ;)


ISJ description
---------------

ISJ can show you all information about superblock of volume,
in particular - the status of dirty flag. Also,
ISJ allows your HDD to use only 2nd superblock.
(Pasha had a situation when physical bad block was located on
first JFS superblock - it's really not well)


If you see at system bootup a message like "Can't .... <do something>"
and after booting you see drive letter but no files
(with message "Run chkdsk /f ...") - you should run ISJ with "-c" switch
and ISJ set dirty flag to "no check".

Then you can reboot with access to this volume (without checking it),
and you should back up all data from volume.

STRONGLY RECOMMENDED:
	reformat this volume after data of volume back up.


Additional information
----------------------

ISJ finds only JFS partition. If you have several JFS partitions,
you can see volume labels and CHS locations. Writing to your HDD
makes only with "-c" switch after interactive confirmation.


Warranty
--------

ISJ is freeware utility from FreeJFS project.
You can use it at your own risk.
