Just got the Charge 2 days ago and plugged it into my PC today. I'm running XP. In Windows Explorer I see 2 new drives with letters, but no names and nothing in them. When I try to create a folder in either of them, I can't do it. The PC downloaded some USB drivers and said "your USB device is ready to use." In Device manager I can see a Samsung device. I've tried mounting and unmounting the SD card; doesn't help. And like I said, I can't even see the phone's card. Anyone have any ideas?
