I have tried swapping the sata cable/slot with a known functioning drive of a 1TB Baracuda, The SSHD was bought last month and is basically brand new, have tried formatting drive to no success, and removed it entirely from the boot order, also interrmittently fails to detect on boot and have to turn off and on for it to be detected. Have also tried SeaTools and it passes both a Short and SMART test, what else can I do but to send it back under warranty or try a long test and format?
