My EVO is acting up. It was working fine one day, I could take pictures, listen to music on my SD card, etc, but then out of nowhere, the phone does not see the SD card. The phone says "Removed SD card. SD card removed. Insert a new one." I have tried removing the SD card, then starting the phone without the SD card, then putting the SD card back in, but it still doesn't recognize the card. I cannot mount the phone as disk drive in my computer (I do not even have the option). Has this happened to anybody else? Does anybody know what I can do to fix this? Thank you!
