To format a drive, please follow the steps below:
Important Note: If you have an Intel-based Mac, you will want to use the GUID Partition Table as recommended by Apple.
(Click to enlarge.)
Double left-click on your Internal Mac drive. Choose Applications then Utilities, and double-click on Disk Utilities.
In the left pane, choose the DataLocker drive that you want to partition and format. Usually there are two listings for each drive unless you have more than one partition on a particular drive. Choose the DataLocker drive listing that is farthest to the left for the drive that you want to format. It is usually directly above the name of the drive.
Under Volume Scheme click the drop-down box and click on 1 partition.
Click the Options button and choose Apple Partition Map then click on Ok.
Change the Format to Mac OS Extended (Journaled). You can also give the drive a name by typing it into the Name box. When you are done, click on Apply.
A box will pop-up letting you know that formatting and partitioning the drive will erase all of the information that is on the drive. If you don’t need any of the information on the drive, then click on Partition. If you do need the data on the drive, you will need to copy the data to another location before proceeding.
The drive is now formatting and you will see a status bar at the bottom that says formatting the diskand gives the name of the drive, the format it is applying and the name that you specified. When it is done, this bar will go away and the drive should now be listed on your desktop.
