Answer 1

Linux has no real notion of drives; it sees one unified filesystem mounted to the root directory (/). An app such as gparted will see drives and partitions, which can be mounted to the existing filesystem somewhere of your choosing.

Partitions, or more precisely, filesystems (which may be the entire drive) can be explicitly mounted to any directory of your choosing that you have permissions to use; to do this, you use the mount command, normally using sudo, since only root can mount filesystems normally. They can also be mounted automatically by opening it in Nautilus.

The best way to permanently use a disk is to include mounting instructions in the file /etc/fstab. That is where all the other mounts are, including the root filesystem, the swapdrive, etc. There is a lot of discussions on how to do this for various situations, and you should search and read some, then perhaps ask questions about specific problems rather than asking for it to be reposted here again.

The end result will look like one big disk, and can be set up in any way you want. Try experimenting first with the mount command to get it set up, then move on to /etc/fstab to avoid mounting it every time you reboot.
