Glad you got it figured out 7. I have been here long enough to know that when you have problems and post for help, they are probably pretty complicated
I have the sandisk 32, and have had no problems. I tried the unmount remount with no issues. And to Myric, my card does take a bit longer than my older 16 for the icon to go away. I have seen a little wierdness with my desk dock, the spinner indicating unmounting sort of hangs, and the occasional need to force a redraw in LP to "unstick" landscape. What I have found with this card and my 16, when booting or docking/undocking, I don't touch a thing until the mount icon goes away. It takes a few extra seconds, but my 32 has not caused me any real issues (and I was sweating it when I bought it).
