I tried to download from my phone to PC using USB. It worked for internal storage but hung on the sd card. After that the SD card was unreadable. I took it to a verizon store and they tried it on a Iphone. It worked. Then it worked on my phone also. I tried downloading using a card reader adapter on the PC and that worked also. Until it got to the bad directory or sector. Then it became unreadable. I'm going to go to the store and see if they can try it on the iphone again and see if that makes it readable again. Has anyone tried this or know if this has worked for anyone else. I think its possible that the iphone did something to make it readable again. I'll let you know if it works again.
