After talking to Motorola technical support for an hour today I learned that when you connect your PC to your Droid Razr Maxx HD running the new Jelly Bean operating software using a USB communication cable and viewing the internal storage and SD card with Windows Explore you will NOT see the typical drive letters assigned any other standard storage devices. You will only see DROID RAZR HD with Internal Storage and SD card listed below NO drive letters. The Motorola technical support person told me that this new with Jelly Bean. This is not a problem if you just want to move files around, but it is a major problem if you use a backup synchronization software like GoodSync. GoodSync does not recognize the two storage devices because there is no drive letters. Has anyone else discovered this or am I getting incorrect information from Motorola technical support?
