S.M.A.R.T. (smart) attribute 190 failing on Seagate Backup Plus 4TB drive

Solution 1:

Just an update for anyone Googling for this attribute, Airflow_Temperature_Cel values are read by SUBTRACTING the reported value from 100. So, for the report:

ID# ATTRIBUTE_NAME          FLAG     VALUE WORST THRESH
190 Airflow_Temperature_Cel 0x0022   040   039   045 

The threshold is actually set at 55 deg C

Current value is 60 deg C

And the worse recorded value is 61 deg C

These values align with those reported in ID#194 Temperature_Celsius

Solution 2:

You can make smart ignore the reading of the value by adding -I 190 -i 190 to the command line in your /etc/smartd.conf config file (See that page). Not sure it affects smartctl behavior though.

Generally, 190 can be ignored as indicator. But, 194 should not and your disk appears to be pretty hot, if you want to preserve it, you should ensure it gets colder. I invite you to read this research paper from Google regarding disk lifetime (with a paragraph for temperatures).

Just in case, you can also run Seagate tests on your disk (if possible), to ensure it's fully healthy SeaTools.
