I got a little less timid and tried running smartctl even though I was
quite unsure of what to expect. It ran. Each of the three USB HD gave
somewhat different output, but none gave output that claimed there was
a working SMART on the drive. These drives are Western Digital (WD).
The WD web site mentions SMART and also uses the words Smart Drive to
mean something else that is a proprietary marketing thing, AFAICT. I
was unable to find a list of part #s for drives that support S.M.A.R.T.
I think I should be in the market for a better class of drives, but not
this weekend. Thanks for the help.
My understanding is that S.M.A.R.T. doesn't generally work over USB.
As Wikipedia puts it:
For example, few external drives connected via USB and Firewire
correctly send S.M.A.R.T. data over those interfaces.

I can use smart on my USB drive enclosure with an ATA drive but not with
my USB drive enclosure with a SATA drive.
