Table 1.1  Status register contents 

Bit Contents 

BIT0=1 

Shown in Table 1.2 

BIT1, 2 

It is not necessary to take any measure when other bits are 
normal, in spite of these bits.  (Normal) 

BIT3=1 

BIT4=1 

BIT5=1 

BIT6=0 

BIT7=1 

 

 

Any of these 
cases. 

(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. 

 
 

Table 1.2  Disposition for error register contents 

Error bit 

Method of disposition 

BIT0 

BIT1 

BIT4 

BIT6 

 

Any of these 
bits are “1”. 

If it is concluded that the disk drive is the cause, replace the 
drive. 

BIT2 

BIT7 

Any of these 
bits are “1”. 

(1)  Check the status of the host, cable, and drive. 

(2)  If it is concluded that the disk drive is the cause, 

replace the 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.
