In my case, adding: hint.ahcich.1.sata_rev="2" to /boot/device.hints seems to have fixed the problem. My dmesg now says: ada1 at ahcich1 bus 0 scbus1 target 0 lun 0 ada1: <ST2000LX001-1RG174 SDM1> ACS-3 ATA SATA 3.x device ada1: Serial Number XXXXX ada1: 300.000MB/s transfers (SATA 2.x, UDMA6, PIO 8192bytes) ada1: Command Queueing enabled ada1: 1907729MB (3907029168 512 byte sectors) Whereas previously it said: ada1: 600.000MB/s transfers (SATA 3.x, UDMA6, PIO 8192bytes) Thanks again, ???
