Looks to me as though you definitely have a hard drive going bad. The
thing that says that to me is "unable to read", not "error reading". I'd
reboot from a DVD with linux rescue, do *not* mount the filesystems, and
do an fsck -c (and any other options) on all the partitions that are
formatted. This will check for bad blocks. If there's only a few, say, 1,
or 10, note how many of them there are, and let it take its default to
mark, and then fix everything else. If there's a *bunch* of them (100+),
you need a new hard disk, now.
