Due to some reason, I have formatted the SD card in my Desire HD. Then when I connect my phone to PC (via USB), its drive, Removable Disk (F: ) icon, disappeared after a few seconds. What should I do to enable PC to read my SD card?

Thanks in advance

2. Right click on "Android Phone" for Properties;
3. Click on Hardware tab;
4. Choose F:\, and go into Driver tab;
5. uninstall F:\;
6. Return and right click on "Android Phone" for troubleshooting;

By this it should return to normal
