The host is notified of the error that the disk drive detected and the user is notified of its result. The user may notice intermittent and indefinite failures such as overlong execution time, abnormal noise, abnormal odor, or failures in particular processes. The failure reported in the operation test will need further investigation. To ascertain the cause of the disk drive failure reported, the disk drive can be replaced. Failures in the operation test are often not caused by the host system. For example, not having enough power supply reserve, a loose cable connection, no timing and mechanical reserves, or relationship with other systems. 1-10 C141-F072
