SYMPTOMS
If you use the Disk Administrator tool (Windisk.exe) from Microsoft Windows NT 4.0 in Windows 2000, the master boot record (MBR) on your hard disk may be overwritten. Disk Administrator assumes that it has not been used with the hard disk previously and prompts you for permission to write a disk signature. If you allow the disk signature to be written, you may experience any of the following symptoms:


 * The drive is accessible by the current installation of Windows 2000, but you cannot update to newer versions and you cannot run disk utilities on the drive.
 * If you attempt to use the Windows 2000 Disk Management snap-in to upgrade the disk to a dynamic disk after the disk signature has been written by Disk Administrator, you receive the following error message:
 * If you use Disk Administrator to make any partition modifications to a disk that has been upgraded to a dynamic disk, Windows 2000 stops responding (hangs) and may generate the following error message when you reboot:

CAUSE
You may run Disk Administrator (Windisk.exe) inadvertently from the Windows NT 4.0 folder in a dual-boot configuration.

Windows 2000 handles disk commands and geometries differently than does Windows 2000 and is incompatible with the Windows NT 4.0 Disk Administrator tool.

RESOLUTION
Do not use Windows NT 4.0 disk management utilities, such as Disk Administrator, in Windows 2000. Use the Windows 2000 Disk Management snap-in in Microsoft Management Console (MMC).
