I removed 2 external usb drives and replaced them with internal drives via sata cables to the motherboard. And now every day I get 2 emails from smartctl saying that the two external drives are missing. That's all fine and good, but I know that, I disconnected them on purpose. For the life of me I can't find where smartctl is getting the list of drives to scan from. There's nothing in /dev/ there's nothing in /etc/smart* nothing anywhere. Where is the list that smartctl is deriving the scan list to send warning emails from?
