you better look in smart table (-a -i, look for remap events in 1st place),
and test with some low-level tool, like MHDD or dd{_resque}.

What was the disk's history?
Was it damaged by external force?
Was it overheated? How many time is on spindle?
How many parks-unparks?
Any strange sounds?
Is read/write graph without strange apexes? (MHDD shows unusual delays,
too, but hdtach can show nice graphs; one can even SIGINFO dd and graph that)
