The disk did not fail.  An I&#x2F;O operation failed.  The first is a permanent condition, the second can be permanent or transient.  Big difference.<p>In Linux a signal can cause an I&#x2F;O to fail.  In Windows it&#x27;s antivirus and other background tasks can cause I&#x2F;O to fail.<p>What can it do to recover?  Retry the I&#x2F;O operation!  It should keep trying until the operator tells it to stop.
