Specified Device Not Found When Writing or Copying Files

The error "Specified device not found" when writing or copying files can arise for several reasons, including incorrect device path, missing access permissions, or even physical damage to the device. In this article, we’ll explore the primary causes of this issue and how to resolve it effectively.

Main Causes of the Error

  • Incorrect device path: This error often occurs due to an incorrect path to the file or drive, such as when the drive letter has changed, or the device is disconnected.
  • Driver issues: Outdated or corrupted drivers can cause the operating system to fail to recognize a connected device.
  • Insufficient permissions: If the user lacks the necessary permissions, they may encounter this error when attempting to write or copy files.
  • Physical device damage: If the disk or USB drive is physically damaged, the system may display a device error.

Methods for Resolving the Issue

1. Check Device Connection

The first and simplest step is to ensure the device is properly connected. If you’re using an external drive or USB, try reconnecting it or using a different USB port. This can help resolve connection-related issues.

2. Update or Reinstall Drivers

Open the Device Manager, locate your device, and try updating its drivers. If updating doesn’t work, try uninstalling the device and reconnecting it so that the system can automatically reinstall the necessary drivers.

3. Verify Access Permissions

Right-click on the device, go to Properties > Security, and make sure you have read and write permissions. If you lack permissions, add the required access or contact an administrator to grant access.

4. Run a Disk Check

To check the device for errors, open the command prompt as an administrator and run the chkdsk command. For example, to check drive D, use chkdsk D: /f. This can help identify and fix logical errors on the drive.

5. Test the Device on Another Computer

If none of the above methods work, try connecting the device to another computer. If the issue persists, the device may have physical damage, in which case data recovery software or professional data recovery services may be necessary.
