In basic disk, if we need to expand partition, we can do it with the professional partition magic. In dynamic disk, we should expand RAID 5 array with professional dynamic disk manager. Before expanding RAID 5, the most important thing we should pay attention to is the data security. Some poor qualified dynamic disk manager may cause terrible effect on data. In Windows operating system, the mostly-used tool is the built-in disk management tool.
This is the built-in disk management tool of Windows. If we try to expand RAID 5, we have to delete the original RAID 5 disk array and then create a new RAID 5 and set the size of it. That causes much data loss and time waste. With professional dynamic disk manager, the operation can be rather easier. We can use professional dynamic disk manager to resize RAID 5 directly with the unallocated space and it won't cause any effect on data in dynamic disk. But there are not much disk management software supporting dynamic disk management. Here I strongly recommend you a powerful dynamic disk manager named MiniTool Partition Wizard.
This picture is the screenshot of main interface of MiniTool Partition Wizard. Before expanding, we should make sure that there is some unallocated space in dynamic disk. For example, the disk list above shows us that all the three disks have unallocated space. The maximum capacity we can use to expand is the smallest one among the three. Click "Move/Resize" button in toolbar to enter into the resize interface.
In this interface, we can expand RAID 5 array by dragging the border of this volume handle rightwards. Click "OK" button after setting.
This picture shows the preview effect of expanded RAID 5 array and this is the maximum capacity of RAID 5, because there is no more unallocated space in the third dynamic disk. At last, remember to click "Apply" button. MiniTool Partition Wizard will execute all operations. Beyond this, MiniTool Partition Wizard has more disk management functions over both dynamic disk and basic disk. Visit the official website to get more information: https://www.partitionwizard.com/.
