Add space to C drive on Windows Server 2008 without reinstalling

It is very common that C drive runs out of space at a certain time after installing Operating System, no matter you use single hard disk or RAID arrays for the server. Nobody likes to start from scratch, so many people search by Google or ask in some forums with similar questions, for example:

  • Is it possible to add space to C drive, as there is plenty of free space in drive D?
  • Is it safe to add free space to C drive from other volumes, will it cause data loss?

In this article, I’ll show you how to add space to C drive in Windows Server 2008 R2 safely and easily. As long as there is Unallocated space or free space in any other volumes in the same disk, you can add the disk space to C drive keeping everything intact.

Which tool?

Server 2008 native Disk Management has Shrink Volume and Extend Volume to resize disk partition, but you cannot shrink D to extend C drive. In most cases, you still need 3rd-party partition software. However, there is data loss risk while doing disk partition modification with software, so you should pay more attention.

Some so-called safe partition software cannot guarantee 100% system and data safe. Actually, even if the partition software is well-designed, some hardware issue such as power failure cause damage, too. To completely get rid of these risks, NIUBI Partition Editor provides 1 Second Rollback technology to protect system and data. If any software or hardware issue occur, it automatically recover to original status in 1 second. With the help of this innovative technology, server can back online without damage in a flash. NIUBI Partition Editor is the only one partition software that can ensure 100% system and data safe.

To add disk space to C drive in Windows Server 2008, you should find out the disk partition layout of your server and follow the corresponding solution below.

Case 1 – add Unallocated space to C drive

Click Server Manager on bottom left corner to open Disk Management, and then you’ll see all disk partitions. As you see, there is 10GB Unallocated space behind C drive.
