ok, so earlier today, i go to mount my evo as a disk drive to copy some files over and i'm no longer able to. when i plug in the usb to the pc (win7 ultimate x64), it starts to charge the phone, but i don't get the option in the notification panel to choose what i want it to do when i plug it in. i've check the phone settings and it's still supposed to ask each time it's plugged in. the sd card is recognized in astro, i even put it back in the hero just to make sure, and everything is there and working. i've tried on my pc (16 different usb slots) and my laptop (4 usb) and neither one will allow me to mount. any ideas on what this could be? thanks for any help!
