Increase partition size server 2003 error

“Hello, I just want to increase my system partition at Disk Management, but I met the increase partition size error in Windows server 2003. I am not sure what’s wrong there, how can I increase partition size in Server 2003 without formatting?”

If you have similar problem in partition resizing, you can find the best solutions here.

When you fail to increase partition space, there are some reasons.

First, you can check if there are any unallocated space on the disk, you can extend the partition space only if there are unallocated space.

Next, you can check if the number you have typed in the size window is too big for your disk partition and there is no enough unallocated space to extend.

The both reasons can lead to a increase partition space error. And here we will provide you with some solutions to increase partition without formatting.

How to extend disk partition size server 2003 without formatting?

To increase disk partition space, you can try Disk Management, the Windows system tool which can resize the partitions easily. While sometimes you may fail to increase disk space, when you try to extend partitions, you find the “Extend Volume” grayed out. Then you can shrink partition first to spare some unallocated space, then you can extend partition easily.

You just need to right click the “Computer” and choose “Manage” to go, then enter “Disk Management” module, then you can right the partition to extend the volume.

But Disk Management may sometimes cause you data loss on the hard drive, you need to be careful. Here I would like to recommend another solution.
