To partition and format the drive with Disk Management, follow these steps:
If you don’t have My Computer on your desktop, it should be located in your Start Menu. You can also find Computer Management in the Control Panel under Administrative Tools.
Important: You may need to initialize the drive. If so, please see the initialization guide 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, right-clickon the blue bar and choose Delete Partition. You will see a pop-up window asking you if you really want to delete the partition. Click Yes. The bar should now be black.
Note: If you would like to create multiple partitions on the DataLocker, you can type in the amount in megabytes you want for the Primary Partition, and it will partition and format only that amount. For example, if you have a 500 GB DataLocker and you want to split the DataLocker into two partitions, you could type in 250000 (for 250 GB's) in the Partition size in MB area.
Once you finish formatting this first partition, you will need to go back and follow all these steps again to partition and format the left-over unallocated area of the DataLocker. The next time around, however, you will need to choose Extended Partion when you come to the Select Partition Typewindow. (Look at previous step.) Remember, when you change or add partition it will destroy any data on the DataLocker. So, be sure to plan how many and what size partitions you want before creating them.
