Googling: sense key recovered error 0x4 0x1d, suggests it's just an
abnormal success message. Use 'smartctl -x /dev/sdc' to extract SMART
info from the drive. If this fails, then it's probably not the best
chipset in the world, hence some commands including smart commands,
You are a better searcher than I...

This is a somewhat old version of smartmontools. Current is 6.3.

Well it might be worth looking on the smartmontools site to see if
ther's a -d option that'll work with your bridge. It might even be
Use smartctl -h to get a usage summary
ARGH!!! This is an HP SFF; I would have to dig out which model, but that
would not help. If the USB bridge is unknown, that fact that it is an HP,
probably will not help.
Or is it the drive? It has been in constant use for 3 years:
It's not the drive. It's most likely the USB>SATA bridge chipset.
Those were pretty much junk 4+ years ago when it came to passing
through the full ATA command set, including things like SMART
commands, and SCT.

Can get a replacement now for 1/2 the price. In fact can get a 2Tb USB
drive for $80 right now.
These days I wouldn't accept an enclosure that doesn't fully support
returning all of the results from a smartctl -x. I just bought super
cheapy PUREX enclosures for some laptop drives for $6 each. They're
USB 3.0, and smartctl -x returns everything including PHY events, and
smartctl -l scterc also works (and is nearly mandatory for any kind of
RAID, the alternative being changing the linux SCSI command timer).
