After about 6 months (or more), I finally decided to create a full recovery drive. I previously did the basic one.
Now the Copy Recovery Partition is greyed out, and if I click on next, it say it can't create are recovery drive on this PC.
I updated (via the MS Store) to Window 8.1 about a month ago.
I've done some checking around, and I think the update to 8.1 is the problem, but I can't find any discussion that says emphatically, "After you update from Windows 8 to Windows 8.1, the Create Recovery Drive option will not function.
