Even though it is not the main drive it is connected to the system and needs checked. As you already know both your drives passed both, Seatools and Crystal Disk tests.
I failed to mention earlier but I was pressed for time, that with memtest, and assuming your RAM is good it will take at least 8 passes and up to 12 to 14 hours to run, most users will start the testing and let memtest run over-nite.
If you have RAM failures earlier than that or immediately follow the procedures for testing each stick and motherboard (MB) slots.
