Hello, I've just installed an SSD into my Mac Pro and have installed all of my apps onto it. I want to use my old HDD for storage, but not sure how to set it up. At the moment it is appearing on my desktop with Snow Leopard and all of my old apps on it. I've backed up all my files onto an external HD and presume I should erase it next, Mac OS Extended (journaled)?. One thing I am wondering is, If I buy something on iTunes how will it know to store them on my old hd and not on the ssd? also will I have the regular OS X folder structure, documents, pictures etc... or will it be the same as a regular external hard drive? Bit of a newbie question I'm sure, but could do with some friendly advice. Thanks.
