Its Western Digitial.
I use to have it on the HD Cage of my Antec Lanboy, but I moved it here like a week ago:http://www.newegg.com/product/product.asp?item=N82E16817998001
and since about yesterday or 2 days ago I starting noticing that it made those sounds. Like it started spinning very fast.
I wanna know its temp for sure, but both Programs I tried to use, wont work, they just make my PC restart, everytimg I try to use them.
