Good morning everyone,
After reading all your messages (a few times), re-examining the man
pages (a few times), and re-visiting the smartmontools web site, I
believe the real problem was that I was seriously misunderstanding the
"Type" column. I thought that it meant that some attributes were
currently at "Pre-fail" levels, and the others were at "Old_age"
levels. I now understand that this column is simply telling me whether
a given attribute
a. will be an indication that the drive *might* be about to fail
if/when in the future it exceeds its threshold, or
b. is simply exceeding its expected lifetime when it exceeds its
threshold (so the threshold value is a life expectancy).

correct.

This apparently was a result of my misunderstanding the "Type" column.
I sit corrected.

I now understand. Thank-you.

I needed a magnifying glass to do it, but I did it. You're correct;
they match.

I did it. I see the error message. Thank-you.

(sigh) Now I need a calculator and a magnifying glass! (just kidding)
I did it. ...about 7 months. That's about right.

> ... Is the drive somewhere where it gets a lot of vibration?
* 2 waste collection trucks each week.
* other occasional trucks (moving vans, delivery/pick-up of "roll-off"
waste containers, etc.).
* large aircraft overhead (I'm directly under one airport approachway
for the city's airport about a mile away.).
* thunder from close lightning strikes in summer thunderstorms.
Nothing really serious. But I see Tony notes the numbers are ok for
Seagate drives.
> It's getting pretty warm there.
The workstation is along the house's north wall with a window above it.
It's slightly chilly in winter (I often need to wear a windbreaker), and
slightly warm (mid 80s degrees F, about 30 degrees C in the late
afternoon) in summer.

No. But I'm now convinced. Thank-you.

> It's normal for Seagate drives.
Good. Thank-you.
In the midst of all this, I discovered a new graphical tool for
smartmontools. It's called "GSmartControl". Its home page is here:
"https://gsmartcontrol.sourceforge.io/home/";.
It's available in Fedora repositories. I installed it and tried it.
Looks good. Maybe others will find it helpful.
I thank everyone for their help. I'm marking this thread solved.
Bill.
