That''s correct. However, normally a disk is able to correct problems by
relocating the impacted sectors. In your case it was an uncorrectable
error which seems to imply the relocation failed and normally that is a
very bad sign.

I''m not sure what the caused it, but I wouldn''t trust it
though.
Of course it might have been a SATA driver issue that hopefully is fixed.

sda2 is a partition, so I hope you meant to say sda.
