Does the firmware impact how / if the Hard drive will function (Mac OS X 10.6)? I am going to be replacing the Hard drive in my Mid 2010 Mac Book Pro (Snow Leopard 10.6.8) and I noticed that on the box the Hard drive claims to support Mountain Lion or Higher. I am wondering if this is just placed there for convenience (claiming to support highest firmware since most people will have it) or if this means that it will not run with OS X 10.6.8? 

HD model: WD WDBMYH0010BNC 

Does the firmware impact how / if the Hard drive will function?
For the Model WD WDBMYH0010BNC 

I found multiple places that claim it will work on 10.6.8.
