Hello Alex, SMART values are collected by the disk itself (smartmontools is only reading it). This would imply that the problem is between disk and controller. Since you have tons of Hardware_ECC_Recovered and none of UDMA_CRC_Error_Count I would think that the problem is with disk itself. I think the long waits are due to disk trying to re-read given sector multiple times. Your drive is 2TB, and according to this the bigger the drive the more likely you'll run into problems like these: http://forums.storagereview.com/index.php/topic/27994-smart-hardware-ecc-recovered-values/ I don't know how serious it is but if you keep anything important there I would recommend a backup. You should try SMART self tests.
