About Disk Management in Windows Server 2012
When you need disk partition management for Windows Server 2012, the built-in tool Disk Management may be the first choice. It displays all the information of each partition and disk including type, file system, status, capacity, free space.
For a hard drive, it allows you to convert basic to dynamic disk, and convert empty MBR to GPT disk and back. For a partition, it enables you to partition a hard drive, format a partition, change a drive's letter, shrink or extend a partition, delete a partition, etc.
However, Windows Server 2012 Disk Management is not good enough for all the situations you may face. For example, Disk Management can only extend a NTFS partition when there is contiguous unallocated space behind it. Even when you shrink a partition, the unallocated space generated will be behind the partition shrunk. You cannot add the unallocated space to another partition but this partition you just shrunk, which is not practical.
Moreover, Disk Management can convert basic disk to dynamic disk, but if you want to convert dynamic disk to basic disk, you need to clean this disk to empty disk first. It also requires the disk to be empty to convert to MBR/GPT disk. Therefore, you may need a more powerful disk management tool.
