Can I Repartition a Hard Disk Drive in Windows 7 without Data Loss?

There is no exception that the hard drive had partitioned already in brand new computer with OEM Windows 7 OS. But sometimes users are not satisfied with the partition which is not reasonable. So they need to repartition hard drive by themselves. There are two situations:

Situation 1: Hard drive only contains single big partition, including the system, boot, and data.

Situation 2: Hard drive is pre-partitioned with a small system drive and other data partitions.

In situation 1, users may launch Disk Management built-in Windows 7 to shrink the only partition and get an unallocated space, then create other partitions. Through this way users could get more partitions than one for different needs.

In situation 2, when you want to create more partitions, you will receive the error message as following:


Why does this error message appear? As we all know that one hard drive could contain maximum four primary partitions or three primary partitions and one extended partition in Window 7. However, it is different from other OS, there are two options when you create partition: create "primary partition" or "extend partition". All of this becomes automatic in Windows 7. Before three partitions existing, you could only create primary partition. Thus once the partition is setting up, there is no way to repartition hard drive without formatting hard drive in Windows 7. We could repartition hard drive through resize partition to solve this problem.

There are several ways for users to resize partition. The DiskPart.exe (a DOS command) and the built-in Disk Management could assist you doing some simple partition resizing operations. However, there are still some limitations of them. It could not work proper as you wish. Thus more and more users choose to use third-party partition software to help them manage their hard drive.
