Cannot make drive dynamic on Marvell-controller.

[ugle43]

I have 4 750 GB disks i want to setup in a software-raid in windows server 2008 R2, to do that they have to be dynamic discs, not basic. I have the P5W64 WS Professional Mobo, with the inbuilt intel-sata-ports, it works just fine to make the drives dynamic, However i only have 3 ports left on it, The motherboard also has a Marvell 88SE6141 sata-controll. If i try to make the drive hooked to that controller, i get the following message: "the request could not be performed because of an I/O device error". There is nothing wrong withe the disc. Is there a way to solve this problem, and also make the last disc dynamic?
