Roy - Your system is so new I don't know which 3rd party has even tested their drives in it yet. You also have some mechanical issues here as the HD mounting is very different than what has been used before. Review the iFixIt guide. You really need to get your system to Apple. I promise you Apple will exchange out under warranty '''Free !''' the HD if it's defective (which from your symptoms it sure sounds like it is). Please don't try opening it up as you don't want to give Apple a reason why they should refuse to repair this under warranty.
