At which point he plugs in his new, free USB flash drive. Jimmy picks up the drive, whistling along to himself as he enters the office and settles down in his cubicle. That “something” is a 512GB USB flash drive! Last Wednesday, as Jimmy got out of his car after parking in the company-owned parking lot, he saw something on the ground. He Does Things With Computers (official title).

I don’t see any reason to use Disk Utility over the Finder when it comes to encrypting a disk. ĭisk Utility can be used to format a disk and enable encryption at the time, though it offers no benefit over just formatting a drive normally and then using OS X to encrypt it using the above steps. In Disk Utility, the option is never available and seems to be permanently disabled. For example, the Finder includes a one-click option to enable or disable disk encryption. Rather surprisingly, Disk Utility is pretty bad at dealing with disk encryption. Again, this process can take some time on larger and slower disks so plan accordingly.

You’ll be required to enter the password for the encrypted volume again, even if it’s mounted, before OS X will disable encryption. Right-click it within the Finder’s Sidebar or on the Desktop and select Decrypt volume name….

If you decide that the volume you’re using no longer needs to be encrypted, it can be decrypted just as simply.

If you’re planning to do this on a portable Mac, make sure you’re in a position where it isn’t going to run out of power and can be left running until it’s finished, so starting it at the airport just before you’re about to board isn’t going to be the best place to do this.

A near-empty 32GB USB 2.0 stick took only a few seconds but a 1TB USB 3.0 drive that’s almost full might take considerably longer.įortunately, OS X still provides access to the volume so you can keep reading and writing data to it though you’ll find you won’t be able to eject it until it’s completed. Finally, disk encryption requires a password hint be provided since forgetting it will mean you can no longer access any of the data the volume might contain, and there’s no amount of data recovery that can bypass this.ĭisk encryption can take anywhere from a few seconds to an hour depending on the size, speed and amount of data on a disk.

You can either specify your own or use the small 🔑 icon to bring up OS X’s Password Assistant to randomly generate one for you. OS X will then prompt you to enter a suitable password. With a suitable Mac-formatted disk connected to your Mac, right-click the volume within the Finder’s Sidebar or on the Desktop and select Encrypt volume name…. This allows you to encrypt a volume already containing files and folders without worrying about copying them back and forth. The Finder includes a built-in option to enable (and disable) disk encryption on a volume without first needing to reformat it, provided it’s Mac-formatted to begin with (see above). If you have a disk formatted in a more Windows-friendly format, such as ExFAT, then disk encryption won’t be possible.

OS X can only encrypt volumes that are Mac-formatted with the filesystem Mac OS Extended, otherwise known as HFS+. OS X can encrypt volumes located on external hard drives and USB sticks in just a few clicks, making it impossible to view the contents of a volume on any Mac unless the correct password is provided. By default, an external hard drive can be accessed on any other Mac without hinderance, so even if you have FileVault 2 enabled on your Mac but you’re backing up to an unencrypted hard drive, it’s rather redundant. Whether you’re using an external hard drive for backup purposes or to provide additional storage for your Mac, it’s important to make sure that whatever information it contains is as secure as possible.
