The error reported task_file_status = 0x4041 on port 3 is a result of an ATA response where the PxIS.TFES bit was set. The ahci driver must do a port reset at that point. The SATA disk failed to perform an operation and reported it. I suspect this is not a data error and may be more on the lines of a firmware fault on the SATA controller. So it may well be a faulty disk in the most unruly way, that is conditional e.g. could be anything around or on the ATA chain, a bad cable, running to hot, interference, mobo firmware ... etc.
