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. > Nevertheless, I reformated sda2 and also performed a double surface scan on > it, but after half a day, it turned out to be ok.
