Hi! My PC will only read the microSD card (2GB one supplied with the phone) installed in my HTC Hero if I remove the card from the phone and plug it directly into the computer. If I simply attach the USB cable, a 'D:' drive appears, but I get the error message "Please insert a disk into drive D". Any ideas? PS: I used the card as is, and did not 'format' it first; should I have done this?!?!?! Thanks!
