Initialize Drive for Mac

G-DRIVE mobile with Thunderbolt has been factory-formatted, or ‘initialized’, for use

with Mac OS. Should you wish to reinitialize the drive—and quickly erase all contents

of the drive—here are the steps:

1. First, open the Disk Utility program, located on your hard drive under Applications/

Utilities/Disk Utility. The window below will appear, and your G-DRIVE mobile with

Thunderbolt will be displayed in the left-hand column.

2. Select your drive by clicking its icon in the left-side column. Information about the

drive will be displayed at the bottom of the window.

3. Select the Erase tab to view the formatting options. By default, the Format pop-up

menu is set to the Mac OS Extended (Journaled) option.
