When I connect my Evo to my PC, I get no option asking if I want to mount the SD card as a disk drive. I get no notification at all that my phone is plugged into a PC. Do I need to install HTC Sync before I can do this? The manual does not mention it if so. I have tried changing the default setting from "Charge Only" to "disk drive" but no change. The "Ask Me" option is also enabled. Any thoughts? I am 3 days new to the Evo, so thank you for any assistance.
