How big is your filesystem?  8207728640*512 is >2T, I doubt
that your 8th partition on your IDE drive is that big... :)

Can you try an xfs_repair -n on /dev/hda8 when it's unmounted,
see if it finds any errors? (-n tells it to not really make any changes,
do it without -n if you really want it to repair).
