Sounds more like a hardware fault than a filesystem corruption to me.
Have you checked to see if anything is being logged by the driver
(eg by checking the output of 'dmesg')?

If there is nothing there, I would use 'dd' to try reading the partition
and/or raw drive from various offsets to see where the read error is
occuring. It seems like the first block has been able to be read  (to
get the partitioning information), but the read is failing pretty soon
in the partition. 

If it really is a filesystem corruption, then you should be able to dd
the entire content of the partition to /dev/null without any errors
being reported.
