Re: Z77 Extreme4 SATA port question
You might get on wegotserved forum and post about this there. While WHS2011 will generally use win7 drivers, it's possible that it just won't work with the ASmedia sata controller. I had a MicroCenter Sataii 60GB SSD drive that I originally wanted to installed WHS2011 on, the installed would get all the way to starting windows server for first time and just hang with the hard drive on. It was an incompatibility with that particular drive, it installed fine on an OCZ Vortex Sata II 60 GB drive.
After re-reading your post, are you saying that one port is recognized and one isn't(recognizes the drive that is), when connected to the asmedia sata III ports?
