How to Fix a Toshiba Laptop I/O Error

DVD Drive
12. Disconnect the AC adapter, close the LCD panel and turn the notebook over. Put on an antistatic wrist band or touch an unpainted metal surface.
13. Release the battery lock, then slide the tab to eject the battery from its compartment. Remove the battery from the TOSHIBA laptop. Locate the DVD drive. Pull on the edge of the drive. If the drive slides out of the laptop, the DVD drive has come loose from the computer.
14. Push the drive all the way into the laptop until you meet resistance. Locate the drive screw, usually found to the left of the serial tag. Tighten the screw in place. If the screw is missing, purchase a replacement screw. Most TOSHIBA models use a flathead 4-mm-long screw for the DVD drive.
15. Reassemble the computer and boot into Windows. Click 'Start.' Click 'Computer' or 'My Computer.' Insert a disc and double-click the DVD drive to run the contents.
16. Right-click the DVD drive if you get another I/O error. Click 'Properties' and 'Hardware.' Select the DVD drive, then click 'Properties' again. Check the 'Device Status' field to see if an error code is listed. Follow the directions on the 'General' tab to resolve the error.
