Fixed: Clean Fail DiskPart SSD Samsung I/O Error in Windows 11/10

An I/O device error, short for Input/Output device error, occurs when Windows is unable to complete an input/output task, such as reading or copying data, while accessing a drive or disk. This issue typically arises from physical damage, like a faulty disk head, logical errors in sectors, or a corrupted partition table.

When faced with an I/O device error, using the DiskPart utility for partitioning may result in failure to access, format, or partition hard drives. Often, users encounter a message stating that DiskPart has encountered an error and cannot perform the requested operation due to the I/O device error.

If you're experiencing this issue, don’t worry—there are several solutions to consider. While most disk I/O errors stem from physical damage, it's worth trying these methods to determine if the problem can be resolved.

If updating the driver doesn't resolve the issue, reinstalling the driver might help:

Step 1. Right-click the disk driver and select Uninstall. Confirm by clicking OK. Restart your PC, and Windows will attempt to reinstall the driver automatically.

Step 2. Alternatively, visit the manufacturer's website to download and install the latest driver updates for your device.

Fix 3. Run CHKDSK to fix bad sectors on the hard drive
