If circumstances prevent the HDD from being mounted as explained below, contact to distributers, reseller, or our sales offices. - Mount the HDD in the specified orientation. Mounting the HDD in an orientaion other than the specified one may adversely affect the temperature or may cause unexpected mechanical stress to the HDD. This may lead to a failure to guarantee the reliability level stated in the device specifications. - Use the specified mounting screw holes. Mount the HDD using the mounting screw holes for each model. If the HDD is attached by a means other than screws or with screws but not at all specified locations (four locations), unexpected vibration or shock may be applied to the HDD or the HDD may mechanically resonate. This may lead to a failure to guarantee the vibration and shock resistance levels stated in the device specifications. - Use mounting screws of appropriate length. A screw shorter than appropriate length is likely to loosen, causing the HDD to drop off the cabinet. A screw longer than appropriate length may touch the HDD body, causing external vibration or shock to the HDD body. This may lead to a failure to guarantee the vibration and shock resistance levels stated in the device specifications. - Ensure clearance between the HDD and the cabinet. Be sure that there is a minimum 2.5 mm clearance between the HDD and the cabinet. Failure to do so may block ventilation and adversely affect the operating temperature of the HDD. It may also cause the HDD to touch the cabinet, which may then induce electrical noise or transmit external mechanical vibration or shock directly to the HDD body. This may result in degraded HDD performance and reliability. Pay special attention to those models whose DE potential is not zero volatage. If this type of model contacts the cabinet connecting the DE to zero volatage, data errors or device faults will occur. Grounding --------- In an HDD with a frame, the DE and frame are electrically isolated from each other. The DE is connected to signal ground (SG); the frame is connected to frame ground (FG). Isolating the DE and frame in this way prevents the adverse effects of external electrical noise. Generally, a computer system uses some means of connecting SG and FG at one point in the system. The method used may vary depending on the system structure or environmental conditions. The DE potential in some models is not zero volatage. Be careful not to ground the DE body of this type of model. SCSI cable connection --------------------- Do not confuse the connector orientation when connecting the SCSI cable. Connecting the cable in the wrong orientation may blow the fuse of the SCSI device that supplies power to the terminating resistor. If the SCSI device has no fuse, misconnection may destroy the SCSI cable. Power-off --------- When power is turned off, a dynamic brake stops the rotating spindle motor. This requires a given time until the motor is completely stopped. Applying vibration or shock to the HDD while the spindle motor rotates after power-off may damage the HDD. Connecting and Disconnecting Interface Connector (2.5-inch HDD) --------------------------------------------------------------- The printed circuit board assembly of the 2.5-inch HDD is about 0.9 mm thinner than that of conventional HDDs. When connecting or disconnecting the interface connector, push or pull the connector straight so as to not give excess stress to the printed circuit board assembly. Never force a connector. Excess stress may cause the printed circuit board assembly to warp or crack, resulting in poor (or no) contact. Hot Plug (SCSI Device) ---------------------- Our HDDs are designed to support the hot plug feature. However, a drop in output voltage, output interruption, or noise may be caused while the HDD is starting. To minimize these symptoms, it is recommended that a discrete power supply be installed for each HDD. Also, connection or disconnection of the HDD may cause noise on the interface signal line and cause an interface malfunction. To prevent such a failure, connect zero volatage (SG) first, then connect the interface line, and finally connect the power line. Reverse the procedure when disconnecting the HDD. When disconnecting the HDD, do not apply vibration or shock to the HDD, before the power is turned off. This may disturb control of the head positioning and degrade data read-write performance. In the worst case, applying excess shock may damage the head or disk, resulting in data destruction. If there is a chance that the power to the HDD containing the terminating resistor will be turned off, design the system so that power to the terminating resistor (TERMPWR) is supplied from another SCSI device. Generally, TERMPWR is supplied from the initiator (host). ********************************************************************** F E A T U R E S ********************************************************************** FUJITSU M2949S JUMPER SETTING 510 KB multi-segment buffer --------------------------- Data is transferred between SCSI bus and disk media through the embedded 510 KB data buffer in the IDD. This buffer can be devided into maximum 32 areas. This feature provides the suitable usage environment for users. Since the initiator can control the disconnect/reconnect timing on the SCSI bus by specifying the condition of stored data to the data buffer or empty condition of the data buffer, the initiator can perform the effective input/output operations with utilizing high data transfer capability of the SCSI bus regardless of actual data transfer rate of the disk drive. Read-ahead cache feature ------------------------ After executing the READ command, the IDD reads automatically and stores (prefetches) the subsequent data blocks into the data buffer (Read-ahead caching). The high speed sequential data access can be achieved by transferring the data from the data buffer without reaccessing the disk in case the subsequent command requests the prefetched data blocks. Error recovery -------------- The IDD can try to recover from errors in SCSI bus or the disk drive using its powerful retry processing. If a recoverable data check occurs, error-free data can be transferred to the initiator after being corrected in the data buffer. The initiator software is released from the complicated error recover processing by these error recovery functions of the IDD. 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. Microcode downloading --------------------- The IDD implements the microcode download feature. This feature achieves easy maintainability of the IDD and function enhancing. SCSI/CCS standard ----------------- The IDD provides not only SCSI basic functions but also the following features: - Arbitration - Disconnection/reselection - Data bus parity - Command set which meets the logical specification of the SCSI CCS (Common Command Set for Direct Access Device) requirements. The SCSI commands can manipulate data through logical block addressing regardless of the physical characteristics of the disk drive. This allows software to accommodate future expansion of system functions. Data security at power failure ------------------------------ Integrity of the data on the disk is guaranteed against all forms of DC power failure except on blocks where a write operation is being performed. The above does not applied to formatting disks or assigning alternate blocks. ECC --- 16-byte data error detection/correction code for the data field. It is possible to on-the-fly, single burst errors with lengths of up to 19 bits, correct single burst errors with lengths of up to 46 bits, correct triple burst errors with lengths of up to 10 bits, and detect quadruple burst errors with lenght of up to 10 bits. Defect list ----------- Information of the defect location on the disk is managed by the defect list. The following are defect lists which the IDD manages. - P list (Primary defect list): This list consists of defect location information available at the disk drive shipment and is recoreded in a system space. The defects in this list are permanent, so the INIT must execute the alternate block allocation using this list when initializing the disk. - D list (Data defect list): This list consists of defect location information specified in a FORMAT UNIT command by the INIT at the initialization of the disk. This information is recorded in the system space of the disk drive as the G list. To execute the alternate block allocation, the FORMAT UNIT command must be specified. - C list (Certification defect list): This list consists of location information on defective blocks which are detected by the verifying operation (certification) of the data block after the initiation when executing the FORMAT UNIT command. The IDD generates this information when executing the FORMAT UNIT command, and the alternate block allocation is made upon the defective block. This information is recorded in the system space of the disk drive as the G list - G list (Growth defect list): This list consists of defective logical data block location information specified in a REASSIGN BLOCKS command by the INIT, information on defective logical data blocks assigned alternate blocks by means of IDD automatic alternate block allocation, information specified as the D list, and information generated as the C list. They are recoreded in the system space on the disk drive. The INIT can read out the contents of the P and G lists by the READ DEFECT DATA command. 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: - Logical data block length - Number of logical data blocks or number of cylinder in the user space - Alternate spare area size This section outlines the formatting at installation. Setting parameters ------------------ The user can specify the optimal operation mode for the user system environments by setting the following parameters with the MODE SELECT EXTENDED command: - Error recovery parameter - Disconnection/reconnection parameter - Caching parameter - Control mode parameter
