When need disk partition software in Windows 2012?

With the release of Windows 2012, we can see that it is much easier for users to mange hard disk partition than the version before. Disk Management built-in Windows 2012 contains “Extend Volume” and “Shrink Volume”, two convenient functions assist Windows 2012 users to shrink or extend existing partition more easily than before.

However, the “Extend Volume” and “Shrink Volume” options can only work on NTFS partition. Besides, you can only extend one partition when it is followed by an adjacent unallocated space.To be specific, when there is no continuous free space to the partition we want to extend on the right side, the “Extend Volume” will be greyed out. Although with the help of “Shrink Volume”, we can get an unallocated space, we cannot move it next to the partition we need to extend.

In this situation, you have two solutions: one is to delete a contiguous existing partition (it is risk to lose important data); another one is to turn to a professional disk partition manager for Windows Server 2012. Apparently, the second one is much safer.
