I see what you mean about the seek dots,..

Why is it different; with 3 partitions on
the 8500 and only 2 on the 780? I tried
clicking the cubes on the info tab but no
response and no information at all on the
health tab. Shouldn't it at least show basic
information like how many hours? I ran error
scan tab and it came back all green.

Thoughts, suggestions?

Will the new HD's be like that?

I can't tell if the Hitachi is on a USB cable, or
is connected to a SATA or IDE internal cable.

USB doesn't usually have passthrough for SMART,
so the window should remain blank.

However, your Info page for the Hitachi is populated,
even if all the tick boxes are ticked, so I can't really
be sure why SMART has gone missing. While it's possible
for SMART to not be implemented on a drive, the Hitachi
has design roots from IBM research, and I think they
played a leading role in SMART. SMART should really be there.
The other bit of weirdness, is HDTune lists a temperature
for the Hitachi, and that would be obtained via SMART.
Temperature is carried in the SMART table.

I have had SMART "freak out" on Windows 10, but that
was Microsoft screwing around, and they fixed that.
It's working again.

My guess is that the Hitachi is a "weird-nick".
That's what the evidence says. There's enough evidence
there to say it should have worked, yet it didn't work
and the table stayed blank.

The Seagate DM003 is still safe to use, provided
you continue to make backups.

I have probably a couple dozen drives here, and I
think all of them have a SMART screen :-) There is
one drive that won't have one, but that's my 4GB IDE
drive from the year 1999 or so. That may predate SMART.
And I have drives that are older than that, that haven't
been powered up in probably 30 years (and are likely
to be frozen via "stiction"). One of those was 250MB
in size (i.e. "huge"). And the heads don't have a ramp
to retract onto, and the heads land on the platter
(that is bad for the heads).

One of the companies did a research project in the lab,
where they allow the platter to spin, and they let the
heads rest on the platter. It takes a whole 30 days,
to grind the heads off :-) The reason they're doing
experiments like that, is planning for the day when
heads no longer "fly". I don't want to buy any of those
drives!
