Is my SD card broken? (Logic analyzer screenshots)

I've been trying to debug PropWare's SD init routines for a long time, so I pulled out "SD Minimal" project from the Simple Library and ran that on the same board with the same SD card and scoped the results. After a loonnngggg time of trying to set the SD card active, it finally dies with the following attempt. The first screenshot is the last two commands that failed, and the second is simply zooming in on the failure.
Does anyone know what's happening here?

Zoom-in
I can rerun the program and attach the full the VCD file if you'd like... but it was large. (~350mb uncompressed)
