OS X: Flash Drive Basics on a Mac


What is a flash drive?

A flash drive is a small, removable hard drive that plugs into a USB port on your computer. You can purchase a flash drive for less than $20 at just about any retail store with an electronics department, and even at some grocery stores and pharmacies. Flash drives are a convenient way to bring your files with you and open them on a different computer. You could also use a flash drive to back up important documents and other files. In this lesson, we’ll show you how to use a flash drive with your computer.

To connect a flash drive:

  1. Insert the flash drive into a USB port on your computer. You should find a USB port on the front, back, or side of your computer (the location may vary depending on whether you have a desktop or a laptop).
  2. Open Finder and locate and select the flash drive from the Sidebar on the left side of the window. Note that the name of the flash drive may vary. You may also see the flash drive on the desktop. If so, double-click it to open the flash drive in a new Finder window.


NOTE: If you don’t see the flash drive on the desktop, go to Finderright-arrowPreferences (you may have to click the desktop first to switch to Finder). Next, make sure the External disks option is checked on the General tab.


To safely remove a flash drive:

When you’re done using a flash drive, don’t remove it from the USB port just yet! You’ll need to make sure to disconnect it properly to avoid damaging files on the drive.

In Finder, click the Eject button next to the flash drive. Alternatively, you can right-click the flash drive and select Eject.


You can now safely remove the flash drive from the USB port.
