Add a disk signature to a disk

A new disk must have a signature on it before it can be used.

When you install a new disk and then do a Rescan, the new disk appears under the Disks icon. You can see the disk with the words "(No Signature)" in the tree view. If left unsigned, the disk cannot be used.

Once you bring the disk online and a signature is added to it, the disk displays as a basic disk. You can create partitions on the basic disk, or you can upgrade the disk to dynamic to let you create dynamic volumes on it.

For earlier version of Volume Manager, the command Upgrade a Dynamic Disk was used to change a basic disk to a dynamic disk. For later versions of the program, use the command Add Disk to Dynamic disk group to change a basic disk to a dynamic disk.

You can also make a basic disk into a dynamic disk by including it as a member disk when creating a new disk group with the New Dynamic disk group command.

To add a signature to a disk

  1. To add a signature, first you need to bring the disk online. To do this, right-click the unsigned disk, and then select Online Disk.
  2. Right-click the disk again, and then select Write Signature from the context menu.

    The Write Disk Signature dialog box appears. Select the disks you want to add a signature to.

    To select a disk, click on it in the list of available disks and click Add. To select all the disks, click Add All.

    To remove a disk from the Selected disks list, select the disk in the Selected disks list and click Remove. To remove all the disks from the Selected disks list, click Remove All.

  3. Select the partition style of the disk by clicking the radio button for one of the following:
    • MBR (Master Boot Record)

    • GPT (GUID Partition Table)

    For more information on both partition styles, refer to the Microsoft documentation.

  4. Once you have selected the disks and style, click OK. Click Cancel to exit without adding a signature to the disk or disks selected.
