the device has either stopped or is disconnected

What does the error message "The device has either stopped responding or is disconnected" mean?

The error message "The device has either stopped responding or is disconnected" typically appears on your computer screen when you attempt to copy files on an iPhone, iPad, phone, USB drive, or SD card.

Do you have any hints as to how this error occurred or what is preventing you from properly copying files from your computer to a connected device, or vice versa? We've outlined some possible factors below:

  • You are attempting to copy a large number of files simultaneously or perform multiple tasks with the phone, SD card, or USB drive.
  • The issue could be related to connectivity. Did you use a card reader for the SD card? Or the original USB cable for your Android, iPhone, or iPad?
  • Driver or hardware issues might be preventing the drive from functioning normally.

To prevent issues with drivers impacting your hard drive, it's essential to keep them updated. A useful tool for this purpose is DriverHandy. This utility automatically scans and updates your drivers to the most recent version. Download it now to give it a try.

General Troubleshooting Solutions

有四个常见的建议，你可以先试试。

Method 1: Reconnect Your Device

Step 1: Disconnect the phone, SD card, or USB drive from the computer.

Step 2: Close all the background applications, then reconnect the device and see if the error continues.

Method 2: Restart Your Devices

Restart your phone and PC. Once they're both off, plug your phone into a USB port to turn both devices back on.

Method 3: Check Your Device Settings

某些手机具有USB设置，可让您单独启用数据连接和充电连接。如果您的手机有此选项，请检查设置以确保USB数据连接已启用。

For an Android phone, the simplest method is to go to Settings > Developer options > Select USB configuration > Choose Audio source while connecting to the computer > Select Media Transfer Protocol (MTP). The device driver will install automatically.

Method 4: Check the USB Port

A damaged USB port might also cause issues. You have two methods to inspect the USB port. First, insert another USB device into the same port on your computer and see if it functions. Second, try using the same USB cable on a different computer's USB port.
