How about the output of "smartctl -all /dev/sdb"?
"Device does not support SMART" (I assume that was --all)
That's probably because it's going via USB? hdparm -i /dev/sdb also gives me nothing useful ("HDIO_DRIVE_CMD(identify) failed: Invalid exchange")
No there are only about two USB mass storage chipsets that support passthrough of the smart commands, neither of which I can actually find built into a USB-SATA or USB-IDE converter. In fact I am so desperate for one for my own drive recovery purposes I am thinking of building my own around one of those chipsets.
As to your question about the entries in messages. Those are basically saying there is a problem getting the data from that block device. In the event that you had a device that supported the full set of SCSI sense keys you would see some diagnostic information here, but really all you are getting is that a read event has failed.
