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.
I agree that it does seem that all USB-SATA/IDE devices seem to be built around the lowest cost components with little regard to serious users.
How does eSATA compare?
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.
Fair enough. A read error pretty much agrees with what I already know!
(Using myrescue to create an image, the disk has only just finished copying after well over a week; there were only ~150 bad blocks out of 48840246, which is a 200G disk. I'm surprised it took that long given that most of the disk read just fine.)
