I have a Seagate Expansion Portable HDD, which I want to check the SMART status of^[Why? For FUN of course!]
I looked at a comment for a WD HDD, which made me look into man smartctl -> /--device after having the message from smartctl -a <dev/path> having:
Read Device Identity failed: scsi error unsupported field in scsi command
If this is a USB connected device, look at the various --device=TYPE variants
Now the manual lists many different possible device types and I am yet, unable to find the correct one. Any ideas would be appreciated.
I tried simply searching for "seagate" in man smartctl, but there was no match in the --device section.
I am currently trying to look for a way to get information on what USB to SATA adapter is being used (hopefully without having to open it up)
Some additional info:

SATA-to-USB bridges, like the one in your external drive enclosure, are notorious for messing up SMART features. You might get lucky, but it might be impossible to do what you want using the enclosure's built-in USB electronics.
If you don't get it working and are determined, you can probably shuck the drive and plug it directly into a real SATA port, on either your motherboard (if you have one) or a known-good USB adapter (if you have a laptop).
I'd like to refrain from that for now, considering this enclosure looks a bit difficult to open (as compared to the older Seagate Expansion model, which I did open, because its adapter went bad) and it's working pretty fine.
Besides, I won't feel like having done something new, in that case.
If it does turn out to work with some combination (I already tried
smartctl -d sat), I can then go ahead and add a tip for the GUI partition manager tool, to implement it there, for others.
