Question: when performing partitioning operations in Windows 7 Disk Management, I mistakenly clicked "Convert to Dynamic Disk" and performed the conversion successfully. Now, all hard disk partitions have become dynamic, and what should I do? I am unaccustomed to using dynamic disk.
3 Situations Where Hard Disk Will Convert to Dynamic
1. If users want to create a new partition in unallocated space when there have been 4 primary partitions on a MBR disk, creating partition will convert basic disk to dynamic. See details from Disk Convert to Dynamic after Create Partition.
2. Users want to extend a partition on basic disk but there is no contiguous unallocated space or free space on the right side. At this time, if a dynamic disk has existed, extending partition will convert basic disk to dynamic disk.
3. Click the function "Convert to Dynamic Disk" by mistake.
Of course after hard disk has become dynamic, users can create much more simple volumes which function like basic partitions or create advanced volumes, such as mirrored volume, spanned volume, and striped volume. Nevertheless, dynamic disk may bring users some problems. For instance, some operating systems can not be installed on dynamic disk, including Ubuntu and a small part of Windows operating systems. For Windows OS that does not support dynamic disk, please see Does Windows 7 Support Dynamic Disks. Moreover, users can perform a fresh Windows installation on a dynamic volume only if that volume was converted from a basic volume and retained an entry in the partition table. Simple volumes converted from basic disks do not have an entry in the partition table unless they were system or boot volumes prior to conversion. Therefore, a lot of users want to convert dynamic disk to basic after their hard disk has become dynamic.
How to Convert Dynamic Disk to Basic
Both Windows Disk Management and Diskpart provide solutions to reverting dynamic disk to basic, but they all require users to delete existing volumes. In Disk Management, just delete all volumes one by one and then the entire disk will become basic automatically. In Diskpart, type these commands successively: list disk, select disk n (n is the number of the dynamic disk), list volume, select volume n (n is the number of a volume), delete volume, select disk n, and convert basic. Every type ends with pressing on Enter key. If there is more than 1 volume, just delete them one by one.
Nevertheless, deleting volumes will result in data loss unless users make a backup in advance. Well then, is there a lossless solution when all hard disk partitions become dynamic? Of course there is. That is to make use of the partitioning software MiniTool Partition Wizard.
Convert Dynamic Disk to Basic with MiniTool Partition Wizard
Just launch the partition manager to get its main interface, select the dynamic disk which will be converted from the disk map, choose "Convert Dynamic Disk to Basic" from the left side or from drop-down list of "Disk" on the top, and click "Apply" button on the top to apply all changes. Note: if the dynamic disk saves Windows which is running, users need to restart computer, and then MiniTool Partition Wizard will make conversion in boot mode:
After changes have been completed, the computer will reboot normally, which shows the problem that all hard disk partitions become dynamic has been solved safely and successfully. For detailed steps and corresponding thumbnails, see Convert Dynamic Disk to Basic.
Note: MiniTool Partition Wizard Free Edition does not support operating dynamic disk, so please download advanced editions for dynamic disk support. Moreover, if users want to convert dynamic disk to basic via this program, only simple volumes are allowed on dynamic disk. If there is mirrored volume, break the mirror in Disk Management. If there is striped, spanned, or RAID 5 volume, delete it after backing up important data. Moreover, if the dynamic disk was a MBR disk before conversion, 4 simple volumes are allowed at most since the maximum number of partition MBR disk contains is 4. And users also need to backup important files and then delete redundant volumes.
