Looks like you need to give a more detailed description of your
problem.

	I don't read comp.unix.questions, so go ahead and
	repost my reply if you want.  I've only seen the
	problem on V2.x though.  The important thing to
	check for is if the disk was write-protected when
	fsck ran.  The applicatable DSA specs require the
	be write-protected if RCT isn't in the correct state.
	If you watch the disk the light will even come on
	when this happens.

	Insufficient information.  It's possible that the time the
	drive spent offline caused BBR to start and after coming
	back online left the RCT in an inconsistant state.  Usualy
	fsck till say that it can't write on the disk (NO WRITE)
	when it starts.  That would prevent it from rewritting the
	clean byte when fsck(8) was done.  There are two possible
	fixes:

	1.  Run radisk.  That may be able to clean up the RCT.

	2.  Backup the disk and get field service to reformat.
