Fujitsu MPC3032AT, MPC3096AT Status register contents, Disposition for error register contents

		Table 1.1 Status register contents
Status bit		Contents
BIT0 = 1	Shown in Table 1.2
BIT1, 2	Normal
BIT3 = 1	(1)	Check whether vibration is transmitted because of the way the disk drive is mounted.
BIT4 = 1	(2)	Check the power, cable, and connector.
BIT5 = 1	(3)	If it is concluded that the disk drive is the cause, replace the disk drive.
BIT6 = 0
BIT7 = 1

		Table 1.2 Disposition for error register contents
Error bit		Method of disposition
BIT0, 4	(1)	If an error occurs in a specific sector, treat that sector as a bad sector or replaced the
		sector.
	(2)	If errors occur frequently, check for problems with the power supply and the
		mounting of the disk drive (disconnect the mainframe, power supply, and disk drive).
	(3)	If it is concluded that the disk drive is the cause, replace the disk drive.
BIT1, 2	(1)	Check the status of the host, cable and drive.
	(2)	If it is concluded that the drive is the cause, replace the drive.
BIT6	Process the bad sector.
BIT7	(1)	Check the status of the host, cable, power connector and drive.
	(2)	If it is concluded that the drive is the cause, replace the drive.

1.2Operation Confirmation

1.2.1Operation 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.
