I'm sorry if this is in another thread, but I've searched for an hour and haven't found a problem exactly like this one. I was able to move a few files to my X from my computer earlier tonight, but I unplugged it from my computer to do something on the phone, and when I plugged it in later, the computer showed the phone storage (drive F) and SD card (drive G). However, I can't open the SD card, and when I go into the SD Card settings on the phone, it keeps going back and forth between Mount and Unmount. The stuff on the card is there and everything works fine when I'm not connected to the computer. But I can't move anything to my phone via USB since I can't get the computer to recognize the SD card. I also noticed that there's no option to format the SD card (well, it's there, but grayed out). Anybody know of anything I can try??
