Hey, I added a second 1TB hard drive to my 2011 MacBook Pro and moved my iTunes library onto it. However, my Mac seems to think that 238.67 GB is being used on the primary hard-drive for iTunes. When I click on 'manage' it shows nothing in there; and I can see my iTunes music is indeed on the second hard drive. Plus, the amount reserved for 'Audio' (182GB) is exactly the size of my iTunes library. So why is 238.67 GB (over 50 GB more than my iTunes library size) being used on the main boot disc?
