(1) Check whether vibration is transmitted because of the way the disk drive
is mounted.
(2) Check the power, cable, and connector.
(3) If it is concluded that the disk drive is the cause, replace the disk drive.

1.2 Operation Confirmation
1.2.1 Operation test
When the host computer is processing data, the disk drive monitors disk drive
operation errors including data, command, and seek errors. 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.
In normal operation, the disk drive itself or the host determines the processing
(return or halt) following the detected failure state.
