Butterfly seeking test mode
I've been testing 2 SSDs where I only select "butterfly seeking" test mode only that resulted in an error. But that is not my problem.
When I run the test using "Default (Cyclic)" test mode, only one of the SSD received the same error. Apparently, for one of the SSD the test skipped the "butterfly seeking" test, but the other SSD it ran this test.
So my question is does the software read the internal setting of the SSD to determine to skip this test, e.g. identify device info?
I've checked the commands sent to the SSD, "SMART read" was issued, so I'm wondering if specific bits in the SMART data structure enabled this type of behavior?
