WDC WD1001FALS-00E8B0 SATA I, not SATA II connection

I’m only posting this out of curiosity, My WDC WD1001FALS-00E8B0 drive reports via WD Dashboard that it is capable of SATA II, (3Gb/s) but is connected at SATA I (1.5Gb/s) speed. Crystal Disk Info shows “---- | SATA/300” as the transfer mode. Any ideas why? I am using SATA ports 1,2,3 on the MB

ASUS Prime B550 +
