         It looks like you may have an unmounted partition, a bad patch 
with lots of bad sectors, or other things wrong.

     I would look at /dev/sda1 with a liveCD or just the CD with Ubuntu 
on it. Tell it to turn on but not install anything. Look at the 
partition and check if it looks like all the other partitions.

         Consider using dd to copy this partition to another empty 
partition.
