Anyone know how to fix this one?

I had a bunch of these. I would get one of the first type when umounting the 
partition fromt he command line. The partition mounts, reads, writes, without 
a hitch aside from these error messages.

Any ideas?

(Started happening after failures reading the disk, maybe do to IDE cable 
problems--a spritz and reconnection gets it working again :-) )
