What is an I/O Device Error?

I/O device is a hardware device that can accept input or output data, send data to a computer and receive data from it. The input device is capable of inputting to a computer, and an output device is responsible for outputting data for the communications between users and computers. Therefore, an I/O device is bidirectional.

An I/O Device Error (short for Input / Output Device Error) usually happens on external & internal hard drives, SD cards, SSD, USB flash drives or pen drives, CD or DVD discs when you are trying to read or copy data in Windows 10/8/7. At most times, it comes with "The request could not be performed because of an I/O device error" message.
An I/O device error indicates that the problem is on a hardware device or media and your computer system becomes inaccessible. But sometimes the problem can also result from faulty programs or drivers. I/O device error is quite common, and many users have encountered it when they attempt to read or write from a hard drive or removable media.

I/O Error

Possible causes of I/O device error

Here list the most common causes of I/O device error:
       1. Faulty or loose connection
       2. Incompatible or corrupt hardware drivers
       3. The storage device is damaged: storage device may contain too many bad sectors or has other physical damages.
       4. The removable media such as CD, DVD, or memory card is excessively dirty or damaged. Since the reasons for I/O device error vary from people to people, it can be resolved by the following solutions.

Solutions to fix an I/O Device error

Solution 1: Perform basic troubleshooting

Before correct these errors, you should first check the cord connections with your computer system. Make sure all the cords are connected tightly to both hub and computer Ports. You can also try to plug the external hard drive to another port of your computer or replace the connection cable to check whether the error is on the cable. Restart your computer/Laptop again, then try to re-access the drive/device to check whether the problem is fixed or not. Otherwise, try another solution continually.

Solution 2: Update or reinstall the drivers

At times, an outdated driver may also cause an I/O device error. This error can be fixed by updating or re-installing a new driver. You need to check whether the drivers are updated and compatible with the disk transfer.

Solution 3: Perform a clean boot

Some programs or services can lead to I/O device errors. You need to put your operating system in clean boot state — that is, to start your system with a minimal set of drivers and startup programs. This method can help you identify exactly which application causes the trouble.
a) Log onto your operating system as an Administrator. Press "Windows + R" key on your keyboard at the same time to open the Run dialog. In this dialog, type “msconfig” and hit Enter to open the System Configuration window.

b) On the "General" tab in the "System Configuration" window, you can see the default setting is "Normal startup." Now you need to select "Selective startup" and untick "Load startup items."

d) Restart your computer, and it will boot into a clean boot state. At this time, try accessing your drive or disk and redo the action that incurred the error. See if the error is gone.
* Note that after you finish troubleshooting, you need to revert the changes you have made to the original settings.

Solution 4: Change the drive transfer mode in IDE Channel Properties

OS cannot transfer data from drive to computer if the transfer mode is incorrect; you can change transfer mode by following steps.
1. Press (Windows + X) both Keys together and select device manager from the menu list
2. Expand IDE ATA/ATAPI controllers. A subset will open, that lists the different IDE ATA/ATAPI channels.
3. Right-click on the channel where the appropriate drive is connected, and then click properties. Typically, this channel is the secondary IDE channel.
4. Go to the advanced settings tab and select PIO Only in the transfer mode box for the device that represents the appropriate drive. Typically, this is device 0. Then, click ok and exit all windows.
5. Test the drive and check if the error message has been removed.
* Warning: Do not change the Primary IDE Channel, Device 0. Changing this transfer mode setting may cause the computer operating incorrectly.

Solution 5: Check and repair device in Command Prompt

1.      Press (Windows + X) both Keys together and select Command Prompt (Admin) from the menu list
2.      Click Yes to allow OS to launch the Command Prompt as Administrator.
3.      In Command Prompt window, type chkdsk G: /f /r /x. Here G is the drive letter; you can replace it with your drive letter.
This option will check and repair disk errors on the external & internal hard drive/USB drive/SD card to fix the I/O device error. 

Solution 6: Change transfer mode in IDE channel properties

The operating system cannot transfer data between computers and devices if the transfer mode for the drive is changed or incorrect. You can fix the problem by changing the transfer mode for the drive via the following steps:
1. Open "Device Manager." Right-click on "This PC" icon from the desktop and choose "Manage" from the displayed menu. Choose "Device Manager" from the "Computer Management" window.
2. Locate and expand IDE ATA/ATAPI controller, and you can see many channels listed here. Right-click the channel which is throwing the I/O device error, and select "Properties" option. If you cannot identify which IDE channel should be chosen, then select the one labeled "Secondary IDE Channel."
3. On the Advanced Settings tab, select PIO Only in the transfer mode box for the device. Then restart the computer and test the drive if the I\O device error is fixed.

Solution 7: Contact the hardware manufacturer

If you've tried the methods mentioned above and the problem still exists, you may need to seek help from experts. You can contact the technical support of the hardware manufacturer or computer to get further assistance. They can help you find out the cause of the error and have your devices repaired or replaced.
