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--47+ * * X | Master * * X | (Default setting) ---50--48+ ---49--47+ * * * | Slave * * * | ---50--48+ ---49--47+ * * * | Cable Selection * xxx | ---50--48+ ---49--47+ * xxx | NEVER ATTACH A JUMPER HERE!!! * * * | ---50--48+ ********************************************************************** I N S T A L L ********************************************************************** IBM DBOA-2720/2540/2528/2360 DRIVE SPECIFICATIONS S85G-3810-00 Notes on Installation ===================== Installation direction ---------------------- horizontally vertically +-----------------+ +--+ +--+ | | | +-----+ +-----+ | | | | | | | | | +-+-----------------+-+ | | | | | | +---------------------+ | | | | | | | | | | | | | | | | | | +---------------------+ | +-----+ +-----+ | +-+-----------------+-+ +--+ +--+ | | | | +-----------------+ 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. ********************************************************************** F E A T U R E S ********************************************************************** IBM DBOA-2720/2540/2528/2360 DRIVE SPECIFICATIONS S85G-3810-00 General Features ---------------- - AT Attachment Interface (Enhanced IDE) - CHS and LBA mode support - Integrated Controller - Multi Zone Recording (8) - Enhanced ECC On-The-Fly - 128-bit Reed Solomon Code operation 10-bit symbol - Multi Burst OTF correction - Automatic retry on errors - Self-diagnostics in power up and in execute drive diagnostics - Closed-loop actuator servo (Embedded Sector Servo) - Rotary voice coil motor actuator - Automatic Actuator lock - Dedicated head landing zone Acoustics --------- Sound Power Levels The upper limit criteria of the octave sound power levels are given in Bels relative to 1 pico Watt and are shown in the following table with A-weighted levels. +-----------+----------------------------------------+ | | Octave Band Frequency (Hz) | +-----------+----+----+----+----+----+----+----+-----+ |Mode | 125| 250| 500| 1k | 2k | 4k | 8k | LwAu| +-----------+----+----+----+----+----+----+----+-----+ |Idle | 4.8| 4.1| 3.6| 3.6| 3.9| 3.9| 3.6| 4.5 | +-----------+----+----+----+----+----+----+----+-----+ |Operating | 5.0| 4.3| 4.2| 4.2| 4.2| 4.2| 3.8| 4.8 | +-----------+----+----+----+----+----+----+----+-----+ Background power levels of the acoustic test chamber for each octave band are to be recorded. 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.
