This is your problem (well, symptom). The disk isn't failing hardware-wise, but it is seeing a lot of transmission errors. The ATA bus errors in dmesg seem to agree with that. I'd say you have a problem on the SATA bus. That can be either a faulty controller, faulty wiring or a faulty SATA chip on the disk. If you can, try to swap the disk positions or connectors. If the problem remains on ata3, the problem is in the controller. Similar tests can help you rule out faulty cables.

As Camaleon has said, for Seagate drives this isn't necessarily true. My WD drives keep the raw value strictly at 0, but the Seagates I use always report very high read error rate (same goes for ECC recovered). They seem to me more like debug flags than actual counters. I find it more instructive to look at the longevity indicators in the middle (VALUE, WORST and THRESH), because they help interpret the raw data without requiring you to read a data sheet.
