One thing to check is the controller properties in Device Manager. While
SATA is a single Channel host, the properties still show as Primary and
Secondary with Auto detection. Toggle any unused channels to None.

Also many vendors ship SATA II tech drives with a micro-jumper that
limits them to SATA I performance levels - make sure the jumper has
been removed ( if installed ).

thank for this suggestion, unfortunately I didn't found these parameters. In
Device Manager (hw configuration) under 'Controller SCSI and RAID' I've only
'ATI AHCI compatible RAID controller' and 'ATI RAID Console'. In the
properties folder I see only: General, Driver, Details and Resources, but I
don find your suggested parameter.
Could you explain in deep where I have to check?

I've already checked and I've removed the SATA I limitation jumper before
the installation.

thank you for patience
