You said this is a USB attached drive. That probably showed up
because the USB bridge doesn't support passing a given SMART
command(s) to the drive.

So we know that one sector was reallocated. Whether that happened when
e2fsck attempted to write to it, or earlier, we don't know.

Other than that one sector, the rest of the drive looks to be useable
so far.

Again, that confirms to me the drive reallocated one bad sector, and
the rest of it seems to be OK so far.

You asked about this in an earlier message. The selective test portion
is used to report the status of the automatic testing the drive does
by itself if that's enabled, and your smartctl output shows that
automatic self tests are enabled on your drive. All the above says is
that the drive isn't running automatic self tests right now, so nothing to
worry about here.
