• Avoid Extreme Conditions: Do not expose the flash drive to extreme temperatures, direct sunlight, or high humidity.
• Handle with Care: Avoid dropping the device or subjecting it to strong impacts, despite its drop-proof design.
• Regular Backups: While the flash drive is a backup solution, it is good practice to periodically back up its contents to another storage medium (e.g., cloud storage, computer hard drive) for ultimate data security.

  • Close and reopen the "U-Disk" app.
  • Ensure your iOS device and the "U-Disk" app are updated to the latest versions.
  • Restart your iOS device.
