How to Fix an IO Device Error

Any I/O (Input/Output) device -- such as a keyboard -- that is connected to a computer is given a specific I/O address. The I/O address enables the computer to recognize and locate any I/O device attached to it. However, system updates and software glitches may cause an I/O device error. If an I/O device error is appearing on your screen, you can use the "Chkdsk" command in Windows to fix the error.

Instructions

1. Click "Start," then type "cmd" into the "Search" box. The "Command Prompt" window will open.

2. Right-click "cmd.exe" in the results list, then select "Run as administrator" from the pop-up list. Type your administrator password into the appropriate box if prompted, then click the "Continue" button. The "Command Prompt" window will open.

3. Type "Chkdsk /R X:" at the command prompt, where "X:" is the drive letter of the volume that needs to be checked. Press the "Enter" key.

4. Press the "Y" key when prompted by the system to check the selected drive when the computer is restarted.

5. Close any open applications, then restart the computer. The system will check and repair any I/O errors that it finds.
