One very frustrating error that many Windows users keep on reporting is the I/O device error. I/O stands for Input/Output. So an I/O device error means there is an issue with reading/writing from/to your hard disk. This error shows up on devices like USB, external hard disk, HDD, SDD, DVD, CD etc. Once this error shows up, you will not be able to copy data to or from this device.
There are many reasons why you could be getting an I/O device error. Try out the methods listed one after the other to fix your issue.
