This can't be as difficult as it seems. Just to make sure the SD card is clean I formatted it, then mounted the SD card and using doubleTwist did the following: - Brought my iTunes playlists into doubleTwist - Selected the one I wanted on the Droid (named "Mobile Phone") - Drug it to the connected Droid and the songs start transferring just fine (there's only about 300 in this playlist). - Transfer gets about 70% completed and just hangs up. DoubleTwist at this point is hung up so can't unmount the SD card. Unplug the USB cable - Now when I go to the SD card it says "SD card is busy" but of course nothing is happening. - At this point I have to do a battery pull to gain access to the SD card in order to format it again Vicious cycle...tried several times...just won't work. Any ideas? Thanks.
