I have Windows 7 Ultimate running with an i7 processor and a Verizon HTC VX6800 Windows 6.1 phone. Following MS directions the phone is connected to the PC via USB and Mobile Device Center. Windows Media Player was used to create a playlist. My 16gb memory chip has 14 gb available after Outlook and other mobile applications are installed. Using Media Player I start the sync from the pc's music library to the phone's library on the memory card installed in the phone.
It's been syncing nearly 24 hours a day for 9 days so far and although music is being transferred, so far only 7gb of music has reached the phone. This is just wrong!
