I have a 120GB SSD that I boot from and would preferably like to keep this as free as possible. I have all of the Jam Packs and would like to install these now but can only seem to be able to select the boot drive to install them onto. I have 2 1tb Caviar Blacks with nothing on right now. Do they have to go on the boot drive? They will fit if need be, I'd just prefer to keep the boot drive less cluttered. Any advice would be great. Thanks!
