is performed when it becomes possible to transfer 2 blocks of data [16 x (32/256)], from the data buffer.
b.Buffer empty ratio
This parameter specifies the timing for the IDD to start reconnection when it is requested by the INIT to transfer data in the WRITE, WRITE EXTENDED or WRITE AND VERIFY command. In a write operation, after the IDD receives a command, the IDD begins transferring data (data
The value specified in this parameter (n) indicates a proportion of the total data buffer capacity of the IDD when the buffer is empty [n/256]. (Note)
While the IDD is writing data to the disk media, it is using the data
Note:
If the value specified for the "buffer full ratio" or the "buffer empty ratio" is not within double the integral boundary of the logical data block length, the IDD rounds up the specified value to the nearest data block boundary. In addition, if zero is specified for any of these parameters, the IDD an appropriate value for the parameter that is determind by IDD.
