How can I control whether Windows 2000’s dynamic disk upgrade is available on my computer?

Windows 2000 introduced the concept of dynamic disks, which let you implement RAID-type disk configurations (e.g., disk mirroring, fault-tolerant striping) and make disk and volume changes without rebooting. Although Microsoft doesn’t support dynamic disks on most laptops, you can enable a dynamic disk on your laptop. Alternatively, you might want to prevent users from upgrading their desktop computers from a basic disk to a dynamic disk.
A registry key controls the ability to upgrade a disk to a dynamic disk. To set this registry key, perform the following steps:

  1. Start a registry editor (e.g., regedit.exe).
  2. Navigate to the
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\IDConfigDBCurrentDockInfo

sub key.

  1. Double-click DockingState and set its value either to 0 (to enable the dynamic disk upgrade option) or to 1 (to disable the upgrade option).
  2. Click OK.
  3. Close the registry editor.
  4. Restart the computer.
