If your disks are SATA I am assuming that perhaps your windows installation 
media doesn't have SATA drivers slipstreamed in. 

Question to all: Does XEN always try to use IDE? Or if the physical disk is 
SATA does it present the disk as a SATA drive?

I am unsure because I tend to use disk image files so we can migrate domUs 
between servers easier.
