Hopefully, you can easily solve the external hard drive I/O device error without moving forward.

Fix 2: Ensure all the cords are working

The next simplest method for solving I/O errors on an external drive involves addressing cord crosstalk. Because electrical signals from one set of wires have a tendency to seep into another set of cables, potentially causing disruptions to the connection during input-output operations. 

  1. Disconnect all extra devices on your computer except for the external hard drive and essential accessories. (Permanently avoiding this problem can be achieved by swapping out the existing cables with higher-quality ones. )
  2. Additionally, you can connect your external drive to a different system to assess whether the cord is defective or if there's an issue with the external drive itself.
