I would agree, but last time I had a similar problem, I was able to mount,
move /home to another drive, reinstalled and ran just fine. I have yet to
try that.

In any case, it seems that the first corrupted block is not 0, this was a
one-time message. Now it all points out to blocks with 6 digits, about 10
consecutive ones. I guess I would use a live cd to check things out, or move
them to safety, if I can. Hopefully, these are just these few bad blocks.
