>   5 reallocated-sector-count    100   100    50   1 sectors   0x010000000000

That's your bad sector. The sector got reallocated.

libatamsart is correctly reporting an issue here. If I were you I'd probably not trust that disk anymore.
Comment 2 Lennart Poettering 2009-05-26 13:41:16 EDT
Oh, could you provide me with the smart blob data you can generate with 'skdump --save=blob /dev/sda' please? As it appears libatasmart fails to parse attribute 9 and 240 correctly. That's something I should fix.

How old is that drive, roughly?
