How to Solve the I/O Device Error – 5 Solutions

What Is an I/O Device Error?

An I/O device error usually occurs when your computer fails to communicate with a storage drive (like a hard drive, SSD, external drive, or USB). The full error message is usually as follows: The request could not be performed because of an I/O device error.

Specifically, this I/O device error mainly occurs when you fail to perform the following operations.

#1. Initialize/Clean a Disk or Format/Delete/Create a Partition Using Disk Management or DiskPart.

Step 1: Launch MiniTool Partition Wizard and click Data Recovery on the toolbar.

Step 3: After the scanning process, find and tick the files to be recovered under Path and Type. Then, click Save and select a safe location to put these files. Finally, click OK.

Solution 1. Check Physical Connections

Replug the storage device and check if the issue disappears. If not, you need to try a different cable or port.

For external drives, change the USB cable and port. For internal drives, change the SATA cable or SATA/M.2 port.

If necessary, you can test the drive on another PC.

Solution 2. Ensure Enough Power Supply

Insufficient power supply to the disk can also cause the I/O device error. To solve this issue, take the following measures.

• For External Drives: Plug it into the rear USB port, or use a two-ended cable/external power supply。
• For Internal Drives: If your lights, fans, and controller are taking too much power and delivering this I/O device error, unplug them or upgrade the PSU.

Solution 3. Update the Uninstall the Storage Device Driver

Sometimes, the reason why computers and devices cannot communicate properly is due to inappropriate drivers. Then, updating or uninstalling the driver may solve the issue. Here are the steps.

1. Press Win + X and choose Device Manager to open it.
2. For HDD, SSD, or external hard drive I/O device errors, expand Disk drives, right-click the disk, and then choose either Update driver or Uninstall device.
3. For USB flash drive I/O device errors, expand Universal Serial Bus controllers, right-click the device (usually USB Mass Storage Device) that appears when plugging the USB drives, and then update or uninstall it.
4. Restart the PC.

Solution 4. Delete Partition or Clean Disk in Certain Situations

If the I/O device error occurs when you access, copy, move, or delete a file, you may be able to delete the partition. Then, create the partition again and see if the issue can be solved.

If the I/O device error occurs when you format or delete a partition, then DiskPart clean may still work normally. Clean and initialize the disk. Then, check if the issue has been solved.

To DiskPart clean a disk, open DiskPart from Windows Search, and then use the following commands:

• List disk
• Select disk * (* is the disk number of the hard drive to be cleaned)
• Clean

Solution 5. Check for Bad Sectors

In most cases, the I/O device errors indicate bad sectors. If the drive still has the drive letter, you can run the chkdsk /r command to locate bad sectors and recover readable information.

To do that, open Command Prompt as administrator. Then, type “chkdsk #: /r” and press Enter. # is the letter of the drive where the I/O device error occurs.
