Question : Add Mirror Greyed Out

Lightning strike.

Machine had 3 HD's in it, C, D, and E.

Two died: C: and D:.

D and E were mirrored.

E is OK.

Reinstalled Win7 on to a new C. That's working.

Installed a new D. That's showing up fine (Same make / model as the other dead drive as well as the alive and well E: drive).

E: showed up as a foreign disk, so I imported it.

E: is healthy.

D & E are the same make, model and size. Both are dynamic disks.

However, "Add Mirror" is greyed out on both.

How do I re-build the mirror?

Answer : Add Mirror Greyed Out

Delete the volume on the new drive then the mirror option should be available.
