MDT 2010 - Can't install OS on disk 1

Hi

We are running MDT 2010 SP1 at one of our customers, and having problems with Windows 7 installation on a specific model (Lenovo T440). The model comes with two disks:

Disk 0 (SSD) - 14GB
Disk 1 (HD) - 465GB

Our normal task sequence works fine if a machine only has one disk.

I want my OS to be installed on disk 1 and disk 0 empty formatted.

In my task sequence under "New Computer only" I have made two new format steps with a WMI query so it only runs if the machine is a Lenovo T440.

SSD

HD:

And a new step when installing OS with the same WMI query where disk 1 and partition 1 is selected.

But the task sequence install the OS on the SSD Disk (Disk 0) and fails.

Any ideas?

Regards,
