I acquired an used 1Tb Western Digital hard drive and I want to check its health status under Linux Mint 18.2.
I checked its S.M.A.R.T health status and everything is reported as OK. gnome-disk reports only one bad sector.
I ran a short test with gnome-disk and it completed successfully.
I also tried to run a short test with smartctl with the smartctl /dev/sdc -t short command, and it reports a read failure (reads the command output bellow):
smartctl 6.5 2016-01-24 r4214 [x86_64-linux-4.8.0-53-generic] (local build)

Then I tried to run an extended test with gnome-disk, and this time it didn't complete successfully, it failed at 90%.
So I ran an extended test using smartctl using the sudo smartctl /dev/sdc -t long -C command, and here is the selftest log:
smartctl 6.5 2016-01-24 r4214 [x86_64-linux-4.8.0-53-generic] (local build)

Is the hard drive still reliable? Is this failure benign? How should I read smartctl logs in future cases?
