Gary teaches us how to use disk utility to format Mac drives in this tutorial. First, go to your utility folder in your applications folder. Now, look for all the drives connected to your computer. A disk is a physical drive and the volume is a hard disk on your machine. You can partition this to two volumes by selecting the drive and clicking "erase". Now, select the latest version of the Mac format and then choose a name. Click erase, and now a new volume will be created on your computer. If you want to create multiple volumes you can partition the drives and apply it to your computer!
