This morning I noticed that every channel was having to reload upon launching.
When I checked the System information, I saw that my Micro SD Card was no longer installed (it was inserted, however).
This particular card is 14.7 GB and I've been using it since I purchased the Roku, and it was working flawlessly -- until now.
I removed the device, installed it in my PC and it is recognized and I can reformat it, etc.
The Roku will simply no longer mount the device anymore. Can my Ultra be failing? It's been less than a year since I purchased the unit.
