To partition and format the DataLocker with Disk Management, please follow these steps:
If there is a blue bar, then the drive has already been partitioned and formatted. Make sure, that if you have data on the DataLocker drive, you back it up before proceeding. Once you are ready, right-click on the blue bar and select Delete Volume. You will see a pop-up window asking you if you really want to delete the partition. Click Yes. The bar should now turn black.
