Maybe you have "programs" you need moving. For this, and for Windows you UNINSTALL and re-install but select the other drive.
"how do i transfer all the files from the small drive to the bigger one?"
You can't. At least given the story so far. For now just put your data files on the other drive.
hi i've recently bought a laptop that i guess came with 2 hard drives. one has the OS installed on it with 44 GB of memory on it that i've almost filled up. the other hard drive has 240 GB. how do i transfer all the files from the small drive to the bigger one? cut and paste doesn't work.
