Mac Pro won't clean install OSX on new HDD
I have a Mac Pro early 2008 and I was running windows and mac on 2 separate hard drives. I was using the 500gb WD hdd that came with the mac that had mac installed and I just upgraded to mavericks, and I was also using a new WD 1TB hdd for Windows (http://www.amazon.com/gp/aw/d/B0088PUEPK/ref=mp_s_a_1_1?qid=1394048774&sr=8-1). I was using windows more because I was having trouble switching back and forth and sometimes the mac hdd wouldn't show up. I tried a few different things with the harddrive and I just came to the conclusion that the mac hdd was dead. It was the original hdd that came with the Mac Pro so it was pretty old I figured it just died, it wouldn't show up anywhere. Anyways, I bought. 2TB WD hdd (http://www.amazon.com/gp/aw/d/B008YAHW6I) to use for mac and now when I tried to install it with the retail mac snow leopard install disk from apple, it gets to the grey apple logo with the loading circle and just stays there forever. I've left it on for a while and it still stays there, which is the same thing that happened when I tired to reinstall it to the old mac harddrive that I think is dead. I've started up into boot option and the new hdd doesn't show up, idk if it's supposed to show up being that's it's a new hdd or what. So I'm not sure if the hard drive is incompatible or the installer disc is incompatible with this Mac Pro. Or the 2tb is too big, I've heard people run up to 3tb on one hard drive on mac pros and they still run good. So I'm not sure, if anybody could please help I'm sure it's probably something simple. Links to the harddrives I have are above. Thanks a lot !
