  • Page 17: Chapter 1 General Description

    CHAPTER 1 GENERAL DESCRIPTION Standard Features Hardware Structure System Configuration This chapter describes the feature and configuration of the MBA3xxxxx. The HDDs are high performance large capacity 3.5-inch hard disk drives with an embedded SCSI controller. The HDDs support the Small Computer System Interface (SCSI) as described in the ANSI SCSI SPI-4 [T10/1365D Rev.10] to the extent described in this manual.

  • Page 18: Standard Features

    Standard Features Compactness Since the SCSI controller circuit is embedded in the standard 3.5-inch hard disk drive form factor, the HDD is extremely compact. The HDD can be connected directly to the SCSI bus of the host system. Environmental Protection The HDDs comply with the Restriction of the use of certain Hazardous Substances in electrical and electronic equipment (RoHS) directive issued by European Union (EU).
  • Page 19 High speed data transfer Such a high data transfer rate on the SCSI bus can be useful with the large capacity buffer in the HDD. • 8-bit SCSI: The data transfer rate on the SCSI bus is 40 MB/s maximum at the synchronous mode.
  • Page 20 IMPORTANT When Write cache is enabled, you should ensure that the cached data is surely flushed to the disk media before you turn off the HDD's power. To ensure it, you should issue either the SYNCHRONIZE CACHE command or the STOP UNIT command with specifying “0” to the Immediate bit and then confirm that the command is surely terminated with the GOOD STATUS.
  • Page 21 (14) Defective block slipping A logical data block can be reallocated in a physical sequence by slipping the defective data block at formatting. This results in high speed contiguous data block processing without a revolution delay due to defective data block. (15) High speed positioning A rotary voice coil motor achieves fast positioning with high performance access control.

  • Page 22: Hardware Structure

    Hardware Structure The HDDs have a disk enclosure (DE) and a printed circuit board assembly (PCBA). The DE includes the heads on an actuator and the disks on a spindle motor mounted on the DE. The PCBA includes a read/write circuit and a controller circuit. Disks The disks have an outer diameter of 70 mm (2.8 inch).

  • Page 23: System Configuration

    System Configuration Figure 1.1 shows the system configuration. The HDDs are connected to the SCSI bus of host systems and are always operated as target. The HDDs perform input/output operation as specified by SCSI devices which operate as initiator. SCSI bus (#14) (#15) Figure 1.1...
  • Page 24 SCSI bus configuration Up to eight SCSI devices operating as an initiator or a target can be connected to the SCSI bus for the 8-bit SCSI and up to 16 SCSI devices operating as an initiator or a target can be connected to the SCSI bus for the 16-bit SCSI in any combination.

Data Space The HDD manages the entire data storage area divided into the following three data spaces. •...

  • Page 36: Figure 3.1 Cylinder Configuration

    Note: Spare sectors on the last track in each cell are not necessarily placed at the end of the track because of a track skew or a cylinder skew. (Details are explained in Subsection 3.1.3.) Figure 3.1 Cylinder configuration Apart from the above logical configuration, the HDD intends to increase the storage capacity by dividing all cylinders into several zones and changing a recording density of each zone.

  • Page 37: Alternate Spare Area

    User space The user space is a storage area for user data. The data format on the user space (the length of data block and the number of data blocks) can be specified with the MODE SELECT or MODE SELECT EXTENDED command. The user can also specify the number of logical data blocks to be placed in the user space with the MODE SELECT or MODE SELECT EXTENDED command.

  • Page 38: Figure 3.2 Spare Area In Cell

    The number of spare sectors per cell is fixed at 300. This number cannot be changed by users. Track 0 Sector 0 n-m-1 Track 1 2n-m-1 2n-m 2n-2 2n-1 Cell Last track SPR1 SPR299 SPR300 Spare sectors (300 sectors) Note: This HDD manages alternate spare areas for each cell, which is a set of cylinders.

  • Page 39: Track Format

    3.1.3 Track format Physical sector allocation Figure 3.4 shows the allocation of the physical sectors in a track. The length in bytes of each physical sector and the number of sectors per track vary depending on the logical data block length.

  • Page 40: Sector Format

    Track skew Head Track skew Head skew Head Leading logical sector in head p+1 Figure 3.5 Track skew/head skew The number of physical sectors (track skew factor and head skew factor) corresponding to the skew time varies depending on the logical data block length because the track skew and the head skew are managed for individual sectors.
  • Page 41 Gaps (G1, G2, G3) No pattern is written on the gap field. PLO Sync In this field, pattern X'00' in the specified length in bytes is written. Sync Mark (SM1, SM2) In this field, special pattern in the specified length in bytes is written. This special pattern indicates the beginning of the data field.

  • Page 42: Format Capacity

    3.1.5 Format capacity The size of the usable area for storing user data on the HDD (format capacity) varies according to the logical data block or the size of the spare sector area. Table 3.1 lists examples of the format capacity when the typical logical data block length and the default spare area are used.

  • Page 43: Figure

    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 HDD treats sector 0, head 0, and 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.

  • Page 44: Defect Management

    Defect Management 3.3.1 Defect list Information of the defect location on the disk is managed by the defect list. The following are defect lists which the HDD manages. • P list (Primary defect list): This list consists of defect location information available at the disk drive shipment and is recorded in a system space.

  • Page 45: Figure

    The alternate block allocation is executed by the FORMAT UNIT command, the REASSIGN BLOCKS command, or the automatic alternate block allocation. Refer to Subsection 5.3.2 “Auto alternate block allocation processing” of the SCSI Logical Interface Specifications for details of specifications on these commands. The logical data block is allocated to the next physically continued sectors after the above sector slip treatment is made.

  • Page 46: Figure 3.7 Alternate Block Allocation By Format Unit Command

    : n represents a logical data block number : Defective sector : Unused spare sector Figure 3.7 Alternate block allocation by FORMAT UNIT command During FORMAT UNIT command, alternate block allocation is conducted in following cases: 1) Unrecovered write offtrack condition during a media write 2) Uncorrectable Data Error during a media read (certification) *1 If above errors are detected during FORMAT UNIT command, the HDD allocates the alternate block(s) to the defective data blocks.

  • Page 47: Figure 3.8 Alternate Block Allocation By Reassign Blocks Command

    Alternate block allocation by REASSIGN BLOCKS command When the REASSIGN BLOCKS command is specified, the alternate block is allocated to the defective logical data block specified by the initiator by means of alternate sector treatment. The alternate block is allocated to unused spare sectors in the alternate cylinder. Figure 3.8 is examples of the alternate block allocation by the REASSIGN BLOCKS command.
  • Page 48 • Automatic alternate block allocation at write operation If AWRE flag in the MODE SELECT parameter permits the automatic alternate block allocation, the HDD executes two kinds of automatic alternate processing during WRITE command processing as described below: Type 1 (Reassignment of uncorrectable read error sector) 1) Commands to be applied WRITE WRITE EXTEND...
