This is really perplexing. Everyone seems to have a different experience. I have Win7, moto drivers installed, usb mass storage selected, usb debugging on. Even if my phone is asleep, if I plug in the usb cable I get autoplay windows for my microsd external card drive and the 'MOT' drive (internal memory 'sdcard') in about 10 seconds or less. I've never had one problem getting both these drives to open. Windows is set to show all file extensions and show hidden files. On my Bionic I do not have Data Encryption on. Early on, I copied off my microsd info, formatted it in a card reader on the computer, and copied everything back. One thing I did differently was to format the card with 8k clusters even though it came formatted with 32k clusters. Be certain to use the Safely Remove Hardware and Eject Media to unmount each drive separately before unplugging. Other posters have stated that unplugging without unmounting resulted in their internal memory 'MOT' drive no longer being able to mount.
