Please note: Manufacturers cannot guarantee 100% compatibility between USB drives and their products. The functionality of one drive doesn't ensure the same for another, even if it's the same make or model, as memory controller chips can vary. A drive may not be compatible with your specific player or hardware chipset. Recommendations or user experiences may differ. Drives are tested for broad compatibility, but complete compatibility with all hardware cannot be guaranteed. As a result, returns can't be accepted for drives that are generally functional (e.g., if it works on most computers but not on your music hardware).
