Received an interesting message when starting backup

This image is from my Dell Latitude E7240 12.5" Notebook bought factory Refurbished from TigerDirectB2B, haven't touched the 256GB SSD yet.

Double-click image to see 4th partition.

Thanks for the post.
All is good here, right?
I set up another external drive for Macrium Reflect, ran a backup and it never complained.

For the record, I run two backup programs. If one fails me it's a good chance the other won't.
