    CHAPTER 1 GENERAL DESCRIPTION Standard Features Hardware Structure System Configuration This chapter describes the feature and configuration of the hard disk drives (HDDs). The drives are high performance large capacity 3.5 inch hard disk drives with an embedded SCSI controller. The drives 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

    In such cases, we are using the original criteria set by Fujitsu Limited while referring to the restrictions already established by End-of-Life Vehicle (ELV) Directive or by the national environmental laws of the EU member nations.
  • 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 cashed data is surely flushed to the disk media before you turn off the drive's power. To ensure it, you should issue either the SYNCHRONIZE CASHE 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.

    b. Reporting result of self-diagnostics and error indication When all specified self-diagnostics terminate normally, the HDD posts the GOOD status for the SEND DIAGNOSTIC command. When an error is detected in the self-diagnostics, the HDD terminates the SEND DIAGNOSTIC command with the CHECK CONDITION status. The initiator should issue the REQUEST SENSE command when the CHECK CONDITION status is posted.
