Note: In this example, because the drive name contains a blank space, we escaped it with a backslash \. For example, to change to the external/ USB drive named Drive 1, we can get there like this: cd Drive\ 1

This gives us the information we need (the drive name) to then cd change directory into any drive. So that would look something like this when entered in Terminal: Mac:~ username$ cd /Volumes & lsĭrive 3

So we can use this information to get the names of all drives: On Macs, all connected drives (including hidden drives) are mounted/located under the /Volumes directory. The trick is knowing the name of the drive and where it is located. Here is how to cd (change directory) into an external drive using Terminal on Mac computers.
