As expected: Self-tests do not work at all.

The smartctl output in this thread may show that  the problem is not 
specific to your system but specific to this drive model & FW.

Normally above "Self-test execution status" should match "Status" column 
of first row of self-test log. If not, this may indicate a broken 
implementation of self-tests.

On Linux, '-d ata' selects traditional ATA support which does not 
support 48-bit ATA commands. Without '-d ata', more logs may appear in 
'-x' output. Please use attachments for longer smartctl outputs to avoid 
reformatting.
