JD.COM Mall bought a Toshiba mobile hard disk, which arrived today. 7-up official website can't find the serial number. What happened?

It doesn't matter if you can't find this. JD.COM's after-sales service is still guaranteed. I bought and assembled the Samsung Check serial number locally, but official website didn't respond that it was broken by human error and replaced it with another one. It's been good and stable for a year.

It is recommended to use HD tune to test health status and boot time.

More importantly, the mobile hard disk is easily damaged due to many taboos. It is very important to pay attention to and understand 1. If you want to be safe and durable, you should connect a regulated power supply every time. 2. Restart deleting whenever you can't pull it out or delete it. 3. Avoid vibration when using. Any bad contact will break. . . . . . . many
