While most people have no issue transferring files, some people experience slow transfer rates. This is especially true if you are using a third-party program. If you are having problems with items taking a long time to upload to your device, try updating both the device and the software program that you are using.
Slow transfer times are often caused by old firmware. Go to the website for either the SanDisk device or the software program, and download the software. Double-click the program to run the update. Make sure that your device is connected to the computer before you run the update. Let the update finish, and then try transferring files.
Another issue that people experience is that the screen will go white when you try to transfer files between your computer and the SanDisk player. This is usually caused by being in the wrong mode. You should always be in MSC mode when dragging and dropping files between your computer and the device.
If you are in MTP mode, change the mode to MSC, and then try to transfer files again. Also, verify that the USB cable is completely plugged into both devices. If your device is crashing when trying to transfer a single piece of media, the problem could be with the file itself. You should skip the media.
These steps will help you with simple Sansa e260 file transfer. If you are experiencing different types of file transfer issues, contact SanDisk for additional assistance. You could also take the device back to the store if it is still under warranty.
