If more than the above mentioned defective block is detected the alternate block assignment processing for the first defective block is executed but the alternate block assignment processing for the second one is not executed and the command being executed terminates However the initiator can recover the twice error by issuing the same command again When an error is detected in a data block in the data area recovery data is rewritten and verified in automatic alternate block allocation during the execution of the READ or READ EXTENDED command Alternate block allocation will not be made for the data block if recovery is successful Example Even if the data error which is recoverable by the WRITE LONG command is simulated automatic alternate block allocation will not be made for the data block C141 E235 CHAPTER 4 Installation Requirements 4 1 Mounting Requirements 4 2 Power Supply Requirements 4 3 Connection Requirements This chapter describes the environmental mounting power supply and connection requirements 4 1 Mounting Requirements 4 1 1 External dimensions Figures 4 1 show the external dimensions of the HDD and the location of the holes for the HDD mounting screws C141 E235 4 1 4 2 Installation Requirements The value marked with indicates the dimension between mounting holes on the bottom face Unit mm Figure 4 1 Dimensions C141 E2
