I recently purchased a 3TB external hard drive. While using the disk management tool in Windows I created unallocated space intended to be used for a partition. The system wouldn't allow me to create the partition continually showing an error message that MBR drives are limited to the first 2TB of space available. My question is two fold: How do I return the unallocated space to the primary partition on the disk? How do I then add the secondary partition?
