To partition and format the drive with Disk Management, please follow these steps:
Important: You may need to initialize the drive. If so, please see the Initialization drive here.
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, you back it up before proceeding. Once you are ready to proceed, right-click on the blue bar and choose Delete Volume... You will see a pop-up window asking you if you really want to delete the partition. Click Yes. The bar should turn black.
Note: To create multiple partitions on the DataLocker, you will have to type in a smaller amount in megabytes, and it will partition and format only that amount. For example, if you have a 500 GB hard drive and you want to divide the drive into two partitions, you could type in 250000 (for 250 GB's) in the Simple volume size in MBarea.
Once you finish formatting the first partition, you will need to go back and repeat these steps again to partition and format the left-over unallocated area of the DataLocker. The result will be two partitions on the DataLocker. Remember, when you change, or add partitions it will destroy any data on the DataLocker. So be sure to plan out ahead how many and what size partitions you want before creating any.
