Hi I hope someone can help. I was using Disc Utility today and saw that the top HD is completely full and the one underneath has loads of room. It is causing my Mac to be troublesome yet I can't find where all this data is. I have searched my Library folder which has 6GB in it. Here is a screenshot of the Disc Utility page showing both HD drives. Any suggestions on where I find this mass of data so I can deal with it? Thanks in advance!
