Jeremy, that was actually option 2. I guess the formatting didn't come
through. I hadn't considered that it would be stripped. Sorry.
Yes, I'm figuring just replacing the damaged drive & having the
system do the rebuild. But, I've got VERY limited knowledge of this,
and someone else may look at the test results and recognize other red
flags that I may be missing.

Um, David, you're over thinking the problem ;) If sdc is the only
problem drive all you have to do is replace sdc and rebuild the array.
