    Disappointed. Spontaneous ejection.

    It never worked. It spontaneously ejects itself. Didn’t realize it didn’t come with Best Buy Protection so Best Buy wouldn’t help me. The company did allow a replacement but it’s much easier with BB protection.

    No, I would not recommend this to a friend

      We're sorry to hear about the trouble with your drive. If it's disconnecting or ejecting on its own, we recommend testing it with a different port, cable, or computer to rule out connection issues. If you still face the same problem, please reach out to our support team at: https://support-en.sandisk.com/app/askweb and we'll be happy to help with troubleshooting or a replacement.
