You said you ran e2fsck and it was OK. What was the command?

Normally with an e2fsck on a journalled fs, the app will replay the journal 
and make a few minor checks. This takes about 4 seconds, not the 40 minutes it 
takes to do a ful ext2 check.

I think you might need to fsck without the journal. I know there's a way to do 
this but a cursory glance at the man page didn't reveal it. Maybe an ext user 
will chip in with the correct method
