ERROR_VOLMGR_DISK_DYNAMIC

ERROR_VOLMGR_DISK_DYNAMIC (0xC0380007) is a Windows Volume Manager HRESULT. The disk is already a dynamic disk, so a conversion-to-dynamic operation is not applicable.

What to check for ERROR_VOLMGR_DISK_DYNAMIC

  • Inspect the disk type before attempting another conversion.
  • Use a volume operation compatible with dynamic disks instead of repeating conversion.
  • Back up data before any conversion back to basic; supported conversion workflows can require deleting volumes.
REM Diagnostic context: ERROR_VOLMGR_DISK_DYNAMIC
diskpart
list disk
select disk <number>
detail disk
list partition

Do not use clean to diagnose a layout problem: it removes partition information from the selected disk.
