I was wondering how would i go about adding adding a 1TB Hard drive to my system and how could i make it to where only my OS and programs stay on the old 160 GB one and all my files, docs, and music go to the 1TB one?
Install the 1TB hard drive inside the machine, partition and format it then move your current doc's, music and stuff to the 1TB drive and save stuff there in the future.
Once you get the 1tb drive installed formatted and partitioned how you want it, it'll just be a matter of dragging and dropping all the files you want to move to the drive. Your OS and programs will stay on your primary hard drive.
