 Jumper Setting
 ==============

 Drive Address Setting
 ---------------------
 A jumper is available at the interface connector to determine the
 drive address.

 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.

 Mounting Orientation
 --------------------
 The disk drive shall operate in all axis (6 Directions). The disk
 drive shall operate within specified error rates when tilted +/-5
 degrees from these positions.

 Performance and error rate must stay within specification limits if
 the disk drive is operated in the other permissible orientations from
 which it was formatted. Thus a disk drive formatted in a horizontal
 orientation must be able to run vertically and vice versa.

 The recommended mounting screw torque is 3 +/- 0.5 kgf.cm.

 The recommended mounting screw depth is 3.5 +/- 0.5mm for bottom and
 5.0 +/- 0.5mm for horizontal mounting.

 The system is reponsible for mounting the drive securely enough to
 prevent from excessive motion or vibration of the drive at seek
 operation or spindle rotation, using appropriate screws or equivalent
 mounting hardware.

 Vibration test and shock test are to be conducted by mounting the
 drive to the table using bottom four screws.


 Shipping Zone and Lock
 ----------------------
 A "shipping" (or "landing") zone on the disk, not on the data area of
 the disk, is provided to protect the disk data during shipping,
 movement, or storage. Upon power down, a head locking mechanism will
 secure the heads in this zone.


 Cabling
 -------
 The maximum cable length from the host system to the drive plus
 circuit pattern length in the host system shall not exceed 18 inches.


 Interface Connector
 -------------------
 The signal connector for AT Attachment is designed to mate with
 Dupont part number 69764-044 or equivalent.


 5V Power (Pins 41/42 of the Interface Connector)
 ------------------------------------------------
 There are two input pins for +5V power supply, +5V LOGIC, pin 41 and
 +5V MOTOR, pin 42. +5V LOGIC is connected to the internal logic
 circuits and +5V MOTOR is connected to the spindle motor and motor
 driver.

 It is possible to turn on and off +5V LOGIC by an external switch
 circuit to reduce power consumption to the least possible. In this
 mode, a voltage drop out due to the motor spin up current can be
 reduced by connecting +5V MOTOR line into the system power source
 directly.

 If the above power management is used, all signal lines that will be
 electrically active in the host system while the drive is
 disconnected from power line shall be isolated by Three-State line
 drivers. Internal leakage through ESD protection circuit may pull
 down LPUL (least Positive Up Level) of logic signal below the spec.

 Use both lines in parallel, for regular drive applications.

 Vendor Unique Functions
 -----------------------
 Drive Lock Function
 Drive Lock is powerful security feature. With a drive lock password,
 user can prevent unauthorized access to hard disk drive even if the
 drive is removed from the computer.

 New commands are supported for this feature as below.
 - Set Password      ('F1'h)
 - Unlock            ('F2'h)
 - Erase Prepare     ('F3'h)
 - Erase Unit        ('F4'h)
 - Freeze Lock       ('F4'h)
 - Disable Password  ('F6'h)

 The Master Password is set to all ASCII blanks (20H) during
 manufacturing and the lock function is disabled.

 The system manufacturer/dealer can set a new Master Password using
 the Set Password command, without enabling the lock function.

 Initial setting user password by System user
 When a user password is set, the drive will automatically enter lock
 mode the next time the drive is powered on.

 Operation from POR after User Password is set
 When drive lock is enabled, the drive rejects media access command
 until an Unlock command is successfully completed.

 Password Lost
 If the user password is forgotten and High level security is set, the
 user can't access any data. However the drive can be unlocked using
 the master password.

 If a user forgets the user password and Maximum security level is
 set, data access is impossible. However the drive can be unlocked
 using the Erase Unit command to unlock the drive and erase all user
 data.


 Warranty
 --------
 The warranty will be covered by contracts.
