A ground/earth fault is a fault where part of the current returns back through a path other than the opposing hot or, more critically, neutral. A neutral/earth fault is dangerous because the circuit will continue to function normally, but the hot and neutral leg currents are imbalanced, and the chassis can become energized.
Since an I/O device error occurs when the Windows OS is attempting to use a transfer mode that is not available or not recognized to or from an input, storage or output device -- such as external hard disk drives, DVDs and CDs, SD cards and USB devices -- the errors can often be fixed by updating a device driver.ince device I/O errors are commonly caused by issues with external drives or peripherals, check the connection, usually a USB connection, and make sure it's correct and snug. If the connection doesn't appear to be the issue, connect the external device to a different computer to see if the same error occurs.
