Hi Grant,

When the OS first tries to mount each of the previously-uncleanly-
unmounted journaled filesystems, you should get a prompt that looks
something like:

  Filesystem (XXX) not cleanly unmounted, you have 10 seconds to 
    hit return to force a check (fsck)...

and then you can choose to run fsck or you can choose to ignore the
message and let the journal do its best to figure out how to proceed. 
In most cases (where there hasn't been any serous damage), you can
safely ignore the message and let the journal take care of it.

Thats the default behavior in recent versions of Red Hat, Mandrake, and
KRUD.  I can't say what the default is for other distros.

hth,
Ed
