Problems You May Encounter When Partitioning Unallocated Space

Unallocated space, or free space, is logical space on a hard drive that the operating system, e. g Windows can write to. It is space that is not allocated to active files within a file system. When you create a new file, the operating system finds available space and allocates that space to the file. Operating systems, like Windows, allocate space on the hard drive as adjacent groups of sectors, known as allocation units, or clusters.

To make use of the allocated space, we sometimes need to follow up with some action. While we may encounter some problems in partitioning: “I want to add unallocated space to my primary drive, how can I do that? I have no idea how to merge unallocated space to C drive; is there any way to add unallocated space to partition without reinstalling operating system? How do I make unallocated space into a normal partition without reinstalling Windows and without the risk of messing something up?” these are some of the problems People may have with unallocated space in partitioning.

Can I Partition the Unallocated Space behind 4 Primary Partitions?

One common problem for many users is that how to partition the unallocated space behind 4 primary partitions, including create primary partition in unallocated space, merge unallocated space to C drive, etc.

Windows built-in Disk Management could be a good way of creating a new partition. The first step is to click the unallocated space in the interface of the Disk management. Then either goes to the menu and selects Action > All Tasks > New Partition… or just right click the unallocated space and select New Partition.

It’s not likely that everyone hopes to delete anything, sometimes we need to merge unallocated space by deleting other partitions, but we can’t merge unallocated space to C drive even if deleting other partitions. What’s more, on some Windows OS, like Windows 2003, or Widows XP, we cannot even extend partition if there are partitions between C drive and unallocated space, as the “Extend Volume” function is not available.
