How to Fix I/O Device Error in Windows 10

The I/O device error message It is usually found on computers with Windows 10, whether desktop or portableThey are also seen, but to a lesser extent, in distributions Linux.

The message itself does not provide any relevant information to try to correct it, you must do your own research to verify the problem.

Yes, an I/O device error will usually point to a problem with some type of attached media, but it doesn't really give you much of a clue as to what's causing the problem, just that it'sThe request could not be processed«.

What Does an I/O Device Error Mean?

First of all, you should know that IS it means "Input and output", and the error implies that access to the device was interrupted.

On a Windows PC, the error means that the operating system is unable to perform a read or write activity on a connected device, i.e. the request could not be completed.

An I/O error It can affect any externally connected media, and is even seen on an internal hard drive that suffers from damaged I/O cables or needs some sort of partition recovery.

The most common peripherals with this problem are:

• External hard drive (USB, firewire or network connected).
• SD Card (I/O cards for mobile phones, cameras and game consoles).
• USB flash drive (Non-volatile flash memory stick without mechanical elements).
• Pen drive (A removable USB flash drive that can only be connected via USB).

The I/O device error will be marked with the letter of the affected drive and usually means a logical problem with a connected device, a failure of hardware pending, or a possible hardware failure.

A logical failure can usually be fixed with software tools that perform partition recovery.

It is likely that the file system of the device storage is damaged or dirty, meaning multiple bad sectors on the media prevent access to data files.

If the failure is hardware-related, there is a risk to data integrity. This may be due to hardware failure, a main battery problem, the hard drive, or the flash drive may have worn out.

Please note that if the file system is fine, you likely have a hardware error. If an error is confirmed, you will need to make a decision on how to proceed.

If you can accept the lost data, simply replace the USB flash drive, external hard drive, or other media; however, if the media contains important files or sentimental content, you should attempt data recovery.

Initial I/O Device Error Investigation

If you receive an I/O error on a piece of storage, the most likely explanation is that the storage is having problems and will probably not return to its normal working state.

I/O errors are typically not attempted to be permanently corrected; rather, they are temporarily adjusted so that data can be extracted.

However, if you're confident you can fix it and aren't worried about further data loss, you can try these basic due diligence checks to rule out any local issues.

Check the physical status of the connection

Look at the first part of the error in the message «The request could not be processed» you are receiving. It will tell you which hard drive you need to troubleshoot.

If the error points to an external drive or anything that is connected via a USB port or USB cable, the first thing you should do is check the connection.

Is the cable plugged in properly at both ends? Try reseating the cable and even try moving the USB cable to another free USB port.

If the problem persists, try replacing the USB cable entirely if possible. Cables break quite easily, especially if they are used on several different devices around the house.

Performing an initial diagnosis is a bit more difficult for an external memory card, SD cards, or USB flash drive. These types of storage drives usually plug directly into the laptop or computer.

All you can really do is reseat the device, clean the connections with a microfiber cloth, and plug it back in.

Use the disk management tool

If the problems persist, the next step is to dig deeper with Microsoft's Disk Management tool and Event Viewer.

To access disk management, press the “Windows keys + R” to open Run. Then write diskmgmt.msc to start the disk management application.

disk Manager Displays information about the hard drive and USB peripherals connected to the PC. Look for a device labeled as removable, you can confirm the drive letter assignment and logical drive partition recovery information.

If you right click on the device, there is the option to “Change drive letter«. If you change the drive letter, you can bypass any computer policies that might block certain drive letters to a network resource.

Also in Disk management, you can right click on the drive or flash drive, then select Properties, look for the tab Tools >> Error checking >> Check and then click Accept in the request message.

With this you can identify and fix errors on a USB flash drive or external hard drives. Windows includes a drive repair tool that will run some integrity checks on the files and the device.

If any are found, Windows will attempt to check and repair any errors on the drive and also confirm whether the drive is connected.

Success at this stage would confirm a logical data integrity issue, likely caused by bad sectors or a dirty file system.

However, you will likely still receive the original I/O device error request; if so, continue troubleshooting.

Use Windows Event Viewer

The next step is to investigate the Windows Event Viewer, which is a tool that records any event that occurs in the operating system, be it a system problem, application problem, network problem, or even an I/O error.

El I/O device error message will have been written to the system event log. Look for the timestamp of the error and then filter the event log for critical, error, and warning messages.

Look for errors that have occurred at the same time - this information can help diagnose the problem with the USB flash drive, external hard drive, or other media.

Some of the most common I/O device error messages to look for are “Only part of a read process memory request was completed»Or«Only part of a write process memory request was completed«.

Search the event log for I/O device error 21, I/O device error 32, or similar I/O device error codes.

How to Fix I/O Device Error in Windows 10

Let’s look at some methods to fix I/O device error in Windows 10.

1. Initial Diligence

There are a number of basic I/O device error troubleshooting tips you can try:

• Step 1: Restart the computer that is displaying the I/O error.
• Step 2: Check the USB port cables and power supply of the external hard drive. Does this action rule out the I/O error?
• Step 3: If you have another computer, try connecting the external drive there. Does the I/O error follow the device? Or can you access the data on another machine and attempt a partition recovery?
• Step 4: If the I/O device error is caused by an attached CD or DVD-ROM, check to see if the DVD is irrevocably scratched or if the device's read/write head is dirty.
• Step 5: Does it work in safe mode? All versions of Windows have safe mode available. In newer versions, you can access safe mode through the symbol of the system and writing «MSConfig«.
• Step 6: Click on the boot tab and check the safe boot checkbox. Now click on the Advanced settings and click debug for additional logging.
• Step 7: Then click Accept and the computer will prompt you to reboot. Once in safe mode, see if you can access the hard drive that is giving the I/O device error.

If you choose to try a home solution, be prepared to accept that any solution could destroy your data files. If you can accept this risk, you can try the following procedures to resolve the problem.

2. Update your device driver

This solution is highly unlikely to work, as storage device drivers are rarely corrupted.

However, this is a possible cause and you should try this solution for peace of mind. Device drivers are microcodes that control how a computer interacts with a storage drive and all other peripherals on your PC.

I/O device errors Driver errors can occur if a computer is shut down improperly, or if an update fails or is patched incorrectly.

To update your device drivers:

• Open the command prompt and type devmgmt.msc to open the device administrator.
• After selecting the device manager, locate the device in the device manager. This will display the storage devices, hard drives, USB drives or flash drives connected to the PC.
• Right click on the device and select “Update Driver«, then choose «Search for drivers automatically» and click OK.
• This will force your computer to connect to the Internet and search for the latest drivers. If that doesn't work, you can visit your device manufacturer's website and search for the drivers yourself.
• Restart your computer and test access to data on the storage device.

Change the transfer mode of the unit

Another possible reason why an I/O device error may have occurred on your device is due to an incompatible device transfer mode between your system and the external hard drive.

You can update this handling mode through the IDE channel properties. Here's what you need to do:

• Start searching for the Start menu.
• Write "Team management» in the text box.
• Then press Enter.
• Changes the transfer mode of the unit.
• Select the option «Device administrator» in the left sidebar.
• Once you have selected the option Device administrator, look for the option IDE/ATA ATAPI Controller on the right side of the window.
• Double click on it to expand the options.
• Right click on the option «Standard SATA AHCI Controller»And select«Properties«.
• Select the option «PIO only» in the transfer mode box.
• Toca Accept to save the changes and then close all windows to check if the problem is resolved.

Also, keep in mind that you should not change the settings of “Primary IDE channel, device 0» because this is the main system disk where Windows is stored.

Making any modifications to this disk may affect the performance of your system.

Run a forced chkdsk on the device

Chkdsk is a built-in utility found in Windows. It is great for repairing a hard drive or flash drive that has been corrupted.

• Open the command prompt.
• Write chkdsk /f /r /x:
• In this command, /f will fix, /r will repair, /x will disassemble the unit to perform a repair.
• Then restart the computer.

Unmounting the device gives Windows the best chance of repairing the problem. If the disk is in use or is a system partition, you will be prompted to restart your computer to restore the disk. chkdsk can run when the computer starts.

I/O Device Error On Linux Based Systems

The Linux operating system is normally an incredibly robust and reliable operating system. However, hardware defects can also affect Linux systems.

The error message is subtly different on Linux distributions. You will get a shell message that says “Kernel: Buffer I/O device error on device XXX, logical block XXX«.

Here we will focus on Red Hat and CentOS distributions, as these are the most popular systems used in data centers and by small businesses.

• Identify the disk you want to investigate. Type “mount | grep /dev” to list your attached disk.
• Run the disk utility tool BadBlocks to scan the selected disk.
• Then write "sudo badblocks -n -vv /dev/sda1«. This will perform a scan of the hard drive for bad blocks.

Please note that this scan may overwrite data, so do not perform this test if you are concerned about losing important files. The scan will take a long time to complete, but the success rate is usually very high with an I/O device error.

Obtain a input/output (I/O) device error affecting a memory card, SD card, flash drive storage device or USB flash drives is usually the sign of some type of hardware failure.

You may be lucky if you only need to replace the storage device cable or just need to update a device driver, but it's more likely that you're dealing with data corruption at the disk drive level.

We recommend you perform some initial due diligence to rule out any local issues, and you may even want to open a service request with your hardware manufacturer.

If you are not concerned about the data located on the drive, try a homemade solution, just remember that working on a flash drive or USB drive that has a hardware failure can cause further damage or data loss.

If the problem you are experiencing threatens sensitive business data or precious personal memories, we recommend that you send your unit to a specialized service center.
