Thanks for that Steve. And sorry for taking so long to get back to you.
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,
Graham
