5. Logical Data Block Addressing Independently of the physical structure of the disk drive the HDDs adopt the logical data block addressing as a data access method on the disk medium The HDDs relate a logical data block address to each physical sector at formatting Data on the disk medium is accessed in logical data block units The INIT specifies the data to be accessed using the logical data block address of that data The logical data block addressing is a function whereby individual data blocks are given addresses of serial hexadecimal numbers in each drive C141 E230 3 2 Logical Data Block Addressing 1 Block address of user space The logical data block address number is consecutively assigned to all of the data blocks in the user space starting with 0 to the first data block The HDDs treat sector 0 track 0 cylinder 0 as the first logical data block The data block is allocated in ascending order of addresses in the following sequence refer to Figure 3 5 1 Logical data blocks are assigned in ascending order of sector number in the same track 2 Subsequent logical data blocks are assigned in ascending order of track number in the same head Within the same track logical data blocks are assigned in the same way as step 1 3 Subsequent logical data blocks are assigned to sectors in every track except the last track in ascending order of track number in the same cell Within the same track logical data blocks are assig
6. When a write protection is prohibited through the setting terminal the auto alternate block allocation processing specification is disabled IMPORTANT Automatic alternate block allocation is made up to the following quantities during the execution of one command ARRE Twice AWRE Type 1 Eight times AWRE Type 2 Maximum number which can be processed within the recovery time limit 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 E230 CHAPTER 4 Installation Requirements 4 4 Mounting Requirements 4 2 Power Supply Requirements 4 3 Connection Requirements This chapter describes the environmental mounting power supply and connection requirements 4 1 Mou

10. Sense Data and Error Recovery Method of the Interface Specifications for further details Formatting Since the disk drive is formatted with a specific default data format for each model part number when shipped from the factory the disk need not be formatted initialized when it is installed in the system However when the system needs data attributes different from the default format all sides of the disk must be formatted initialized according to the procedures below The user can change the following data attributes at initialization e Logical data block length e Number of logical data blocks in the user space e Alternate spare area size This section outlines the formatting at installation Refer to Subsection 4 1 4 MODE SELECT 15 4 1 5 MODE SELECT EXTENDED 55 of the Serial Attached SCSI Interface Specifications for further details MODE SELECT MODE SELECT EXTENDED command Specify the format attributes on the disk with the MODE SELECT or MODE SELECT EXTENDED command The parameters are as follows a Block descriptor Specify the size byte length of the logical data block in the data block length field To explicitly specify the number of logical data blocks specify the number in the number of data blocks field Otherwise specify 0 in number of data blocks field In this case the number of logical data blocks after initialization is determined by the value specified in the format parameter page c
