How to Sync Music From iTunes to a SanDiskby Stephen A. Powell
While you may be familiar with iTunes' compatibility with the iPod, you may not be aware that the music management and playback utility also works with many SanDisk compatible devices. The iTunes sync process remains the same as when sending files to the original compatible device, but thanks to the utility's expanded capability, you can save to an MP3 player's installed SD card once you've connected it to your computer.
Connect your media player with SanDisk memory card installed to your computer through its USB adapter.
Wait for the player's device icon to appear in the iTunes Source pane.
Drag and drop music titles from the library pane directly onto the device icon. The music will sync onto the player's SD storage.
