Hi:
Running updated Debian on a pretty old iMac.  Seeing messages that complain about sda, only drive in the system:

Interpreting smartctl output is tough. Try to find manufacturer documentation that describes the SMART attributes, etc., for that specific make and model. 


The most important SMART report line to look at is:

SMART overall-health self-assessment test result: PASSED


Please run the following command:

# smartctl -t long <dev>


Run the following command until the test is done:

# smartctl -x <dev>'
Please post the complete, final SMART report. There is much more information than you have posted below.

I have an HDD with Power_On_Hours of 28k+.  It works.

That looks like your drive is overheating. Check cleanliness (e.g. dust) and cooling (fans, airflow restriction/ blockage). If those are good, swap the drive with a known good drive, run the above commands, and post the results.

I have drives with worse numbers for Hardware_ECC_Recovered.  They work.
