This is not possible, as USB does not transfer the relevant
commands. The only way os to open the enclosure, remove the disk
and connect it directly.
Note that some known incompetents here claim differently, but
have as of now failed to provide any proof.

Depends on your USB drive chipset.
Some chipsets from Cypress and Oxford do support passing S.M.A.R.T. ,
others do not.

Don't buy from Ebay?...
Thanks for the replies.
I'm buying a new Seagate FreeAgent external USB hard drive on Ebay. I
wanted to use S.M.A.R.T. to confirm that it is in fact a new drive. If
S.M.A.R.T. won't work on a USB drive, is there any other way I can
confirm that the drive is new?
Thanks.

As there is no standardized vau to transport SMART over USB, these do
not work. Only some (few) chipsets have non-standardized ways and
they work only with the respective tools for specifically that
chipset.

pass-through said:The current USB mass storage specification is based on a version of
SCSI (SPC-2) that can't support SAT. But some chips manufacturers
implement proprietary SCSI commands that allow ATA pass through

through SCSI commands) for which some information is publicly
available...
The SCSI to ATA Translation (SAT) standard (ANSI INCITS 431-2007) may
solve many problems in this area. It defines how SCSI commands will
be translated to the corresponding ATA commands and defines a
pass-through mechanism.

The only way is to open it.
As it is Ebay, you might not have warranty anyways.
One it is open, connect it directly to get SMART data,
and look on the label to see the manufacturing date and a possible
refurbishing date.
However I would strongly advise not to buy HDDs on Ebay.
All it takes is one good drop to kill a drive, possibly weeks
or months after the event.

It looks like only certain Cypress chips provide the necessary
pass-through <smartmontools.sourceforge.net/faq.html#testinghelp>:
But it looks like external monitoring /can/ get better in the future (ibid):

Hi all,
Here is a page that claims to list all known USB-to-IDE bridge devices,
and whether or not it is possible to transport SMART data over them:
http://www.hdsentinel.com/usbharddisks.php (from the makers of "Hard Disk
Sentinel" software).
Of course, as others have pointed out, this relies on non-standard
extensions of the USB mass storage protocol, since the official standard
does /not/ support SMART-over-USB. As far as a I know, the only free/open-
source software support for these non-standard extensions is in
smartmontools' support for some Cypress chips: http://
