#2. Utilizing Diskpart for Windows 2003 Extend C Drive
To extend C drive on Windows Server 2003 with Diskpart commands, there must be a continuous unallocated space next to the C drive. This is the precondition that enables you to utilize the Diskpart command to take effect. Otherwise, you'll receive an error message that prevents you from executing the next command.
Error: The volume you have selected may not be extended
The volume you have selected may not be extended.
Please select another volume and try again.
The reason behind the error message is concerned with the precondition as we've explained. It's due to the lack of unallocated space. In addition, the system volume can only be extended by running Diskpart.exe from a command line by a bootable CD.
How to solve common errors and extend C drive in Diskpart
Step 1. Open Diskpart Command Prompt in Windows Server 2003
Input Diskpart in the search bar, and click "OK" to enter the Diskpart Utility.
Step 2. Extend C drive with continuous unallocated space
"x" in the examples refers to the number of a hard disk or partition.
- Input list disk command, and press Enter. Then, all of the disks will be listed.
- Input select disk x command to select the target disk, and then press Enter.
- Input list partition and press Enter. Then, all the partitions will be listed.
- Select the number of system partition that needs to be extended by inputting select partition x and pressing Enter.
- Input Extend command, and press Enter.
- Input Exit to leave the Diskpart window.
Step 3. Extend C drive with non-continuous unallocated space (Data backup is required)
When there is no unallocated space right behind system volume, you have to delete the adjacent drive to get unallocated space and then increase the C drive by inputting the relevant commands followed by the Enter key.
"x" in the examples refers to the number of a hard disk or partition.
