A. Win2K 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 subkey.
  3. 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).
  4. Click OK.
  5. Close the registry editor.
  6. Restart the computer.
