System Protection: Available Drives... (D:) (Missing)

I went into System Properties (W7 64) and under System Protection, I found a list of Available Drives.  However, it had entries such as:
DATA (D:)
DATA (D:) (Missing)

Why do I have entries for Missing drives?  Where are these pointers stored?  How can I correct this?

Thanks--
Sam

Did you ever have a D: drive or partition which you have perhaps merged into another drive?
Do you see a D: drive in Start|Computer?  In Disk Management?

I still have a D drive (I received this same message for several other local partitions too).

Any ideas re:

I understand you have a Drive D: and it contains data but not the operating system.  Is that correct?
When you highlight Drive D: in the System Protection tab and then click Configure, what are the settings?  Have you assigned Disk Space to the Restore Points for D:?  Have you dotted the circle for "Restore System Settings..."?

The Restore Point for System Restore are in the System Volume Information  folder.  It is a Hidden Operating System folder.

One way to fix System Restore is to turn it off (that means click Delete on the Configure window and then turn it back on.  The disadvantage is that you lose all existing Restore Points.
