There are some considerations to make when you change a basic disk to dynamic.
Consider the following:
You cannot upgrade a basic disk if it contains a system partition or a boot partition.
Once you change a basic disk to a dynamic disk, the volumes on the disk cannot be accessed by MS-DOS, Windows 95/98, or Windows NT.
After you upgrade a basic disk to a dynamic disk and create dynamic volumes on it, you cannot change the dynamic volumes back to partitions or basic volumes. You can revert a dynamic disk to basic, but you must delete all dynamic volumes on the disk and then use the Remove Disk from Dynamic Disk Group command.
On Windows Server operating systems, you can upgrade a basic disk to a dynamic disk that can be contained in a Microsoft Disk Management Disk Group or in an SFW dynamic disk group as follows:
If you upgrade a basic disk to a dynamic disk in a Microsoft Disk Management Disk Group, you can add it to an existing Microsoft Disk Management Disk Group or use it to create the Microsoft Disk Management Disk Group. You are not able to have more than one Microsoft Disk Management Disk Group.
If you upgrade a basic disk to a dynamic disk in an SFW dynamic disk group, you can add it to an existing SFW dynamic disk group or use it to create an SFW dynamic disk group. You can have multiple SFW dynamic disk groups.
When a basic disk with existing partitions is converted to a dynamic disk, all handles to the disk must be closed before the conversion. This means that all applications using the disk must be stopped before starting the conversion operation.
