In addition to what others have already said, in theory keep an eye on
the Wear_Leveling_Count  that its not close to zero. Also, some AHCI
errors can be generated due to a controller issue or cable issue.  Try
smartctl -x on your drive as it sometimes gives more info.  If the disk
has not logged any smart errors yet you see it in dmesg, it might not be
the disk at issue, or at least the disk doesnt think so.
