 Cable Selection
 ---------------
 Using Cable Selection, the drive address depends on the condition of
 pin 28 of the AT interface cable. In the case when pin 28 is ground
 or low, the drive is a Master. If pin 28 is open or high level, the
 drive is a Slave.


 49-Pin
 When grounded, no spin-up at POR.
 When open => pull-up, normal spin-up at POR.

 The drive will operate in all axes (6 directions). The drive will
 operate within the specified error rates when tilted  5 degrees from
 these positions.

 Performance and error rate will stay within specification limits if
 the drive is operated in the other permissible orientations from
 which it was formatted. Thus a drive formatted in a horizontal
 orientation will be able to run vertically and vice versa.
 The drive must be securely mounted in the system to prevent motion or
 vibration during a seek operation or spindle rotation using
 appropriate screws or equivalent mounting hardware.

 Vibration and shock tests are to be conducted with the drive mounted
 to the equipment using the bottom four screw holes.


 Air Cooling Requirement
 -----------------------
 The host system must provide sufficient air flow across the drive to
 maintain the temperature at less than 60*C (meas-ured at the centre
 of the files' top cover).


 Operating Shock
 ---------------
 The drive will withstand (with no hard error) a 100G half-sine wave
 shock pulse of 2ms duration.


 Non-Operating Shock
 -------------------
 The drive will withstand (with no permanent damage or degradation in
 performance) a 120G half-sine wave shock pulse of 11ms duration or
 500G for 2ms.


 Operating and non Operating Vibration
 -------------------------------------
 Due to the complexity of this subject we recommend that users contact
 the Distributor to discuss how to perform the necessary measurements
 if they believe this to be an area which requires evaluation.

 Warning: This disk drive can be damaged by Electro-Static Discharge,
 please follow recommended ESD procedures before unpacking or handling
 the drive. Ask your Dealer for details if you need assistance.
 Adaptive Battery Life Extension IBM Travelstar products incorporate
 software which automatically determines the correct time to start
 removing power from the drive electronics.

 Most software and operating systems make use of a disk drive in
 bursts. The Travelstar drives monitor the commands which are sent
 from the host and detect patterns which indicate that a command
 sequence is active or has completed. The drive can then conserve
 power after each command sequence is finished by putting the drive
 into low power power idle mode. The result is lower overall power
 consumption and longer battery life with no loss in performance. If
 the host system changes the number or frequency of commands which it
 sends then the disk drive will adapt automati-cally to this new
 pattern.


 Electromagnetic Compatibility
 -----------------------------
 The drive meets the following EMC requirements when installed in a
 host system and exercised with a random accessing routine at maximum
 data rate:

 United States Federal Communication Commission (FCC) Rules and
 Regulations Part 15, Subject J - Computer Devices "Class B Limits".
 European Economic Community (EEC) directive #76/889 related to the
 control of radio frequency interference and the Verband Deutscher
 Elektrotechniker (VDE) requirements of Germany (GOP).


 Operating Environment
 ---------------------
 Humidity: Operating 8% to 90% Relative non-condensing
           Non-Operating 5% to 95% Relative non-condensing

 Wet Bulb Temperature:
 Maximum Wet Bulb: Operating 29.4*C non-condensing
                   Non-Operating 40*C non-condensing Operating Modes

 To provide the greatest flexibility of operation with optimum
 performance and power consumption the drive has a number of operating
 modes. These are defined below.

 Active Mode
 The drive is performing a command, writing cached data to disk or
 filling a read ahead buffer.


 Performance Idle
 ----------------
 The drive is spinning but is not per forming a command. It can
 respond immediately if a new command is received. The transition
 from active mode to performance idle mode is controlled by the
 arrival and completion of commands from the host system.


 Low Power Idle
 --------------
 The drive is spinning but is not per forming a command. Additionally
 the drive had determined that the previous command sequence (group of
 associated commands) is complete. Some of the drive electronics have
 been powered down but it can still respond to a new command within
 about 40 milliseconds. The transition from performance idle to low
 power idle is controlled by IBM's patented Adaptive Battery Life
 Extension technology.


 Standby
 -------
 The drive is not spinning and is not performing a command. All
 electronics except for the command interface is turned off. The
 transition to standby is controlled by a programmable timer which is
 set by the host system using standard ATA commands. After receiving a
 new command, the drive will start spinning again and perform the
 command within 2 to 3 seconds (typically).


 Sleep
 -----
 The drive is not spinning and is not performing commands. All of the
 electronics is turned off. The transition to sleep mode is controlled
 by a command which is sent by the host system. The transition from
 sleep can only be triggered by a reset.

 Caution
 DO NOT PRESS!


 S.M.A.R.T. Function
 -------------------
 The intent of self - monitoring, analysis and reporting technology
 (S.M.A.R.T) is to protect user data and prevent un-scheduled system
 downtime that may be caused by predictable degradation and/ or fault
 of the device. By monitoring and storing critical performance and
 calibration parameters, S.M.A.R.T devices employ sophisticated data
 analysis algorithms to predict the likelihood of near - term
 degradation or fault condition. By alerting the host system of a
 negative reliability status condition, the host system can warn the
 user of the impending risk of data loss and advise the user of
 appropriate action.

 Since S.M.A.R.T. utilizes the internal device microprocessor and
 other devices resources, there may be some small overhead associated
 with its operation. However, special care has been taken in the
 design of the S.M.A.R.T algorithms to minimize the impact to host
 system performance. Actual impact of S.M.A.R.T. overhead is dependant
 on the specific device design and the usage patterns of the host
 system. To further ensure minimal impact to the user, S.M.A.R.T
 capable devices are shipped from the device manufacturer's factory
 with the S.M.A.R.T. feature disabled. S.M.A.R.T capable devices can
 be enabled by the system OEMs at time of system integration or in the
 field by aftermarket products.
