Working with Scratch Disks and Hard Disk Drives

By default, Final Cut Pro uses the hard disk on which the application is installed as your scratch disk to store captured and render files. Ideally, you should use a hard disk other than your main system disk as your scratch disk. Depending on how much space you need for your media, you can have up to 12 scratch disks in your Final Cut Pro editing system.

Important: If you have multiple hard disks and partitions, make sure they do not have similar names, or you could encounter problems during capture. For more information, see Using Multiple Hard Disks.
