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
