That's good and bad...  good that you have a journaled system, but: I think
that means you already _have_ a serious problem with your partition.  I was
wondering about the "Invalid argument during seek" - that looks more like
either your system is using the wrong drive geometry (BIOS settings?) or
hardware failure.  

Still umounting it and fscking will work if things aren't already totally
broken.
