Dynamic disks are marked as Invalid on a computer that is running Windows Server 2008 or Windows Vista when you bring the disks online, take the disks offline, or restart the computer

Consider the following scenario:

  • You create more than 99 volumes on one or more dynamic disks in a computer that is running Windows Server 2008 or Windows Vista.
  • The size of one of the volumes is larger than 2 TB.
  • You bring online all dynamic disks, take offline all dynamic disks, or you restart the computer.

In this scenario, you cannot access the volumes. In the Disk Management snap-in of Microsoft Management Console (MMC) window, all the dynamic disks are marked as Invalid. Additionally, if you try to make these disks active, you receive the following error message:

“The operation is not allowed on the Invalid pack”
