Hi,
If your bios is set to AHCI mode and no UEFI (dont know what happens in this case), you can see the actual numbering of the disk using windows device manager.
In the general properties of each disk there is a "channel" number which gives the "true" physical number of sata connector (sata 0 to sata 5), the one written on the silk screen (yes, sometimes miracles happen).
Your SSD should be channel 0 and your HDD should be channel 2.
It is not obvious that windows numbering in Windows disk management assigns the same number.
ie. I have two HDD in sata3 0 and 1 and disk numbers are disk 0 and disk 1, however when I plug an e-sata disk (sata #5) it is channel 5 in properties and becomes disk 2 in disk management.
HDD disk 0, why not, if SSD is not considered as a true disk, and the assignement done after true HDD (?).
