did the fsck complete- is it persistent across reboots?

and yes, you can totally do that. if all you need is the data, then you
can do what's outlined at
http://www.redhat.com/docs/manuals/linux/RHL-7.3-Manual/ref-guide/s1-filesystem-ext2-revert.html

MAKE SURE IT'S UNMOUNTED FIRST. (although if it won't mount in the first
place...)


#where foo = device node of your harddisk,

tune2fs -O ^has_journal foo

#then check filesystem just in case

e2fsck -y foo

#then mount it. the contents in ( ) may be necessary, they may not be
depending on kernel options and version of mount, etc.

mount (-t ext2) foo /mnt/bar


#OPTIONAL: remove old journal

rm -f /mnt/bar/.journal
