Sorry if this has been asked before. I did do a search for a solution prior to posting this. Everything worked fine up until today. Now I cant access my SD card from my PC. It keeps saying "preparing SD card"...over and over. On my PC it just shows it as a removeable disk. I can see the files on the SD card from the phone so it appears to be working fine. The phone occassionally randomly reboots itself while plugged into the computer also. Any idea how to correct this?
