HBA's can fail. Cables can fail; usually, it's the connection/ connector. Re-seating cables can fix problems. Connections should feel solid. If not, install a new cable and recycle the old one. I assume there is some utility on BSD to read and pretty-print the smartd information (?). I would download the HGST Windows Drive Fitness Test (WinDFT) and use it to test all the drives. Ideally, by removing your BSD system drive, installing a Windows system drive, installing WinDFT, and running WinDFT before, during, and after you mess with the hardware. David
