Hi, I would like to know if it's possible to disassemble both this: http://www.bestbuy.com/site/olspage.jsp?skuId=8478756&type=product&id=1185267958970 and this: http://www.bestbuy.com/site/olspage.jsp?skuId=8475063&type=product&id=1185271084002 drive to remove from the casing and put in a Mac Pro. I've seen pictures here: http://www.carltonbale.com/2008/01/western-digital-my-book-opening-the-case-removing-the-drive/ on how to disassemble the case, but am wondering if it will work in a Mac Pro. Any help is appreciated. Thanks!
