I have now downloaded and run Seagate's tools and it does show a does

Automatic Write Reallocation Enable (AWRE) is on by default, but
Automatic Read Reallocation Enable (ARRE) is off. If I set ARRE on and
then run the long test (which reads all sectors sequentially), will that
reallocate any bad sectors and mark them as such? Is this a safe thing
to do?
Beware that failures have a way of escalating faster than you expect.
Do you have a good backup of the drive?
If not and the data has high value, do not power up the drive. Pack it
properly and send it to a professional recovery service.

It is common for Wintel-centric tools to only run on Windows. It's good
to keep an operational Windows system drive around. Mobile docks make
swapping drives easy.
Sometimes you get lucky and the tool is a live CD:

SMART is built-in to the firmware of the HDD/SSD; the drive
microcontroller does most of the work. Using the right tools, you can
pull SMART information out of the microcontroller and/or adjust tunable
SMART parameters. As the drive is failing, you especially want those
reports. If you post them here, people can tell you all kinds of
interesting things about your drive.

Take a picture of the screen with a digital camera (or phone), and then
type the exact screen contents into a reply.
