 Mounting screws
 ---------------
 Either side or underside mounting may be used. The drive use M3
 screws which should not extend into the drive frame by more than 3mm
 or damage will occur.


 Frame clearance
 ---------------
 There should be a gap of at least 0.5mm between the drive PCA and
 any adjacent system components to allow for cooling.


 Cooling
 -------
 Cooling should be provided to keep the DE surface temperature
 (measured at the centre of the top of the drive) below 65*C.


 Mounting in Cabinet
 -------------------
 Note the following points regarding mounting of the HDD in a cabinet.
 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).

 Media Defects
 -------------
 Before the unit leaves the factory, media defects are listed on the
 MEDIA DEFECT LIST. This list is written on the media in the SA space
 which is a reserved area of the disk. All media defects found during
 manufacture are mapped out during the format process so the drive
 will appear defect free to the user when first shipped. Any media
 defects that occur once the drive is installed may be mapped out by
 the operating system.


 WARNING
 Magneto-Resistive Read heads are a significant factor in the
 achievement of very high capacities in small form factor hard disk
 drives. The MR head must be electrically biased in order to function,
 and Fujitsu use +5.5VDC on these drives. The voltage is generated by
 the drive electronics from the normal +5VDC and +12VDC rails, so
 standard power supplies and connectors may be used. With the MR head
 biased in this way, it becomes important to avoid the possibility of
 discharge between the head and the media, so, in order to ensure
 operational reliability, the disk enclosure (DE) and hence the
 platters themselves are also biased to +5.5VDC resulting in zero
 potential difference between head and platter. This means that the
 outer casing of the DE is set at +5.5VDC rather than DC Ground as
 would be the case on a conventional drive.

 USERS MUST ENSURE THAT THE DISK ENCLOSURE CASING IS NEVER SHORTED TO
 THE COMPUTER SYSTEM'S FRAME OR DC GROUND.


 Apple Powerbook...
 ------------------
 If you have a notebook computer, any of the Apple Powerbook range,
 or are just short of space in your system there is now no need to
 compromise capacity or performance with physical size. Fujitsu's
 range of high performance 2.5" drives offer amazingly fast access
 times and data transfer rates together with storage capacities of up
 to 520MB.

 At just 17mm (0.67") high these drives are some of the most compact
 available and are probably the best engineered disk drives in their
 class.

 These drives are extremely versatile and are available with SCSI-2
 interface and industry standard mountings and connections to ensure
 maximum system compatibility.
