Extend C: drive in dynamic disk

C: drive is set as primary partition to install operating system when we partition disk and its space is fixed. However, the operating system takes up more and more space as time passes by because it is improved by keeping being updated. Meanwhile, when operating system is running, it also takes up spare space. For the sake of the normal run of operating system in C: drive, we ought to extend C: drive space when encountering lack of space in C: drive. If we use the disk management tool built in operating system to extend C: drive, we need to delete this partition first and then create a new larger partition when reinstalling operating system. This process is complicated and costs a lot of time, though we can extend C: drive with this methods. We can solve this problem with professional partition magic if C: drive is in basic disk. However, if it is in dynamic disk, much partition magic is not available because it doesn't support dynamic disk and run normally in operating system.

Create volume in dynamic disk
The conception of dynamic disk has come out since Windows 2000 and the performance of dynamic disk is approved by computer users. We can easily convert basic disk to dynamic disk with disk management tool built in Windows operating system (select the basic partition and right click mouse, then click "Convert to Dynamic Disk"). We could experience its new features after finishing the conversion. At least two hard disks are suggested because creating volume is based on certain conditions. Except for simple volume, only there are at least two dynamic disks can striped volume, spanned volume and mirrored volume be created. And at least three dynamic disks are needed if we want to create RAID5 volume.

Resize volume in dynamic disk
After creating volumes in dynamic disk, we are supposed to extend C: drive if we encounter lack of space in C: drive. The operation of resizing volume is similar to the operation of resizing partition, both of which can be realized with professional partition magic. There is little software supporting dynamic disk but MiniTool Partition Wizard can make it.

Run MiniTool Partition Wizard. There must be unallocated space adjacent to C: drive. Otherwise, we can not extend C: drive. In the window, the 2.3GB space adjacent to C: drive is unallocated space. Select C: drive and click "Move/Resize" to extend C: drive. If there is no unallocated space, we can shrink D: drive to get unallocated space and then resize C: drive. There is no influence on operating system when we resize C: drive.

If we want to extend simple volume in one dynamic disk in the computer with multiple dynamic disks, we can use the unallocated space on the other dynamic disks to extend it. After extended, the simple volume becomes spanned volume automatically. More information about MiniTool Partition Wizard can be obtained on the official website
