Is SMART really that dumb?

I have never found a way to get smart to report what specific sectors
is pending.

You can do a smartctl -l long against the device and generally it will
stop when it hits that sector.

Also usually the errors are found by linux doing a read against it, so
there should be error messages on the reads in the messages file when
it happened, that is usually what I use to determine what sectors are
getting the error.
