SAS drives will not work on SATA controllers. These are enterprise-grade devices that require a special controller. An SAS controller will run an SATA drive, but not the other way around. I'm going to run over to the ECS site and see if that board supports SAS. And look to see if the IcyDock does, too.
Oddly, my last post was on a thread about a foxconn bloodrage motherboard, which has two SAS ports.
EDIT: I think that you got the wrong drive. The motherboard does not support SAS. The IcyDock does, but that's not enough. It's just a pass-through device.
