I have been having issues the last few times when I have my Droid hooked up to my computer. I can drag my music and pics over to the Droid with no problems. I tried to drag 7 photos over to my desktop and iPhoto locked up on me. Now I am trying to unmount and unplug the USB cable and it won't let me. It keeps saying Disk is in use, try quitting applications and try again! Nothing is open that would cause the disk to be in use. I have a Mac computer. When I first got my Droid, it mounted and unmounted with no problems until recently. It mounts with no problems but unmounting is another story!
