What Does "The device has either stopped responding or is disconnected" Imply

The error message 'the device has either stopped responding or is disconnected' error usually appears on your computer screen when you copy files on iPhone, iPad, phone, USB drive or SD card.

Do you have some clues how did this error come or what prevents you from copying files properly from your computer to a connected device or vise versa? We summarized some of the following factors.

  • You're trying to copy a lot of files together or does multiple tasks at the time with the phone or SD card or USB drive.
  • It's all about the connection problems. Did you use the card reader for SD card? Or the original USB cable for your Android, iPhone or iPad?
  • Driver or hardware problems stopped you from using the drive as normal.

Back up the files you failed to copy from the computer or Android with EaseUS free backup software. Files are very likely to get corrupted during the transfer process.

General Troubleshooting Solutions

There are four common tips that you should try first.

Method 1. Reconnect Your Device

Method 3. Check Your Device Settings

Method 4. Check the USB Port

A broken USB port could also create problems. You got two options to check the USB port. One, plug another USB into the same port on your computer and check it works or not. Two, use the same USB cable on another computer's USB port.
