I/O stands for Input/ Output. In the case of external hard drives, I/O means read/ write. An I/O error is thus an issue with the external hard drive that stops Windows from reading its contents or writing on it. In other words, I/O error means that Windows isn’t able to transfer data to and from the external hard drive.
When an I/O error occurs, it indicates that the external hard drive has encountered a serious problem and has become inaccessible for file transfer. All of the files and data stored on the external hard drive are at risk of being lost permanently when Windows starts displaying an I/O error.
Check the cable that is being used for connecting the external hard drive to the PC and ensure that it is working properly. The drive won’t function as it should if the cable isn’t properly attached. Try using a spare cable and test it by connecting it to a different USB port.
Note: Only a trained professional should attempt to replace the cables of an internal drive of a PC. The reason for this is that you can cause serious damage to the internal parts of the disk if you do this task incorrectly. Thus, cables located inside a portable computer or laptop shouldn’t be changed by ordinary computer users.
If this solution works then your work is done. If it didn’t fix external hard drive I/O error then move on to solution 2.
Check if a driver or program is clashing with the external hard drive by performing a clean boot of the PC. If your issue gets resolved after a clean boot, you might have an incompatible driver or program on your system.
If this solution works then your work is done. If it didn’t fix external hard drive I/O error then move on to solution 3.
Windows won’t be able to transfer data between the PC and the external drive if the drive’s transfer mode is incorrect or has been changed. Correcting the transfer mode of the drive can fix this issue. You need to follow the below-mentioned step in order to perform this task.
Step 1. Press the Start button
Step 2. Right-click the icon labeled My Computer
Step 3. In the menu that appears, choose the Manage option
Step 4. Choose Device Manager option in the window labeled Computer Management
Step 5. Expand the option IDE ATA/ATAPI controllers. You will see a list containing various IDE ATA/ATAPI channels for your PC
Step 6. Press the Properties option after right-clicking the channel that the external drive is connected to. The channel that is usually used for external hard drives is Secondary IDE Channel
Step 7. Choose PIO Only option in the box labeled Transfer Mode for the device representing your external hard drive on the tab labeled Advanced Settings. Usually, this is Device 0. Close all windows after clicking OK button
Step 8. Check the drive
Warning: Primary ID Channel, Device 0 is used for system disk so don’t change that. Your PC won’t even work if you end up making any change to the settings of this transfer mode.
The drive might not be present there if changing the secondary IDE channel device 0’s transfer mode doesn’t fix your issue. If available, try to change back the transfer mode to DMA using the same process. After that, perform steps 1 to 6 for changing the IDE devices’ transfer mode in the below-mentioned order until the problem is fixed:
1. Primary IDE channel, device 1
2. Secondary IDE channel, device 1
Do remember to reboot your PC after changing your settings to let the system identify the alterations that have been made. Examine the settings after the restart to ensure that they have taken effect. Your external hard drive will start working correctly if the settings are correct.
