Caution: The CS and DS jumpers should never be installed at the same time. DS Drive Select Jumper ----------------------- You can configure two drives on the ATA Interface as Master (Drive 0) and Slave (Drive 1) using the DS jumpers. Set the CS jumpers to OPEN for each drive. Then, set the DS Jumper to CLOSED on one drive to configure that drive as Master. Set the DS jumper to OPEN on the other drive to configure as Slave. Note: For drives configured using the DS jumper, the order in which drives are connected in a daisy chain has no significance. CS Cable Select Jumper ----------------------- When two ProDrive LPS 210/420AT hard disk drives are daisy-chained together, they can be configured as Master and Slave by using the CS jumper or by using the DS jumper - BUT NOT BOTH. To configure the two drives using the CS jumper, set the CS jumper to CLOSED and the DS jumper to OPEN on each drive. Once you install the CS jumper, the drive is configured as a Master or Slave by state of the Cable Select signal, which is pin 28 at the IDE-bus interface connector. Quantum uses pin 28 Cable Select function but does not implement the spindle synchronization function. Pin 28 is grounded - that is, set to OPEN - on the cable coming from the host. This configures the first drive as Master. Then, pin 28 on the connector at the second drive should be made an open circuit by a cut in signal line 28 in the cable from the first drive, so it becomes high - that is, set to CLOSED - due to a pull-up in the second drive. This configures the second drive as a Slave. SP Slave Present Jumper ------------------------ The SP jumper normally is not needed. However, when the ProDrive LPS 210/420AT is configured as Master and is connected to a Slave drive that does not implement the Drive Active/Slave Present (DASP-) signal, it is necessary to set the SP jumper to CLOSED on the ProDrive LPS 210/420AT. ********************************************************************** I N S T A L L ********************************************************************** QUANTUM PRODRIVE LPS 210/420AT PRODUCT MANUAL 81-106898-02, JUNE 94 Notes on Installation ===================== Installation direction ---------------------- horizontally vertically +-----------------+ +--+ +--+ | | | +-----+ +-----+ | | | | | | | | | +-+-----------------+-+ | | | | | | +---------------------+ | | | | | | | | | | | | | | | | | | +---------------------+ | +-----+ +-----+ | +-+-----------------+-+ +--+ +--+ | | | | +-----------------+ The drive will operate in all axis (6 directions). Mounting -------- The mounting holes on the ProDrive LPS 120/240AT hard disk drive allow the drive to be mounted in any orientation. Caution: The PCB is very close to the mounting holes. Do not exceed the specified length for the mounting screws. The specified screw length allows full use of the mounting-hole threads, while avoiding damaging or placing unwanted stress on the PCB. To avoid stripping the mounting-hole threads, the maximum torque applied to the mounting screws must not exceed 8 inch-pounds. Clearance --------- Clearance from the drive - except mounting surfaces - to any surface must be 1.25 mm (0.05 inches) minimum. Ventilation ----------- The LPS 210/420AT hard disk drives operates without a cooling fan, provided the ambient air temperature does not exceed 122*F (50*C). Drive Cable and Connector ------------------------- The hard disk drive connects to the host computer by means of a cable. This cable contains a 40-pin computer that plugs into the drive, and a 40-pin conector that plugs into the host computer. At the host end, the cable plugs into either an adapter board residing in a host expansion slot or an on-board IDE adapter. If two drives are connected by a cable with two 40-pin drive connectors, the cable-select feature of the ProDrive LPS 210/420AT automatically configures each as drive 0 or drive 1 depending on the configuration of pin 28 on the connector. IDE-Bus Interface ----------------- A 40-pin IDE interface connector on the motherboard or an adapter board provides an interface between the drive and a host that uses an IBM PC AT bus. The IDE interface contains bus drivers and receivers compatible with the standard AT bus. The AT-bus interface signals D8-D15, INTRQ and IOCS16- require an IDE adapter board to have an extended I/O-bus connector. The IDE interface buffers data and control signals between the drive and the AT bus of the host system, and decodes addresses on the host address bus. The Command Block Registers on the drive accept commands from the host system BIOS. NOTE Some host systems do not read the Status Register after the drive issues an interrupt. In such cases, the interrupt may not be acknowledged. To overcome thos problem, you may have to configure a jumper on the motherboard or adapter board to allow interrupts to be controlled by the drive's interrupt logic. Read your motherboard or adapter board manual carefully to find out how to do this. J11A/B/C DC Power/Interface Connector -------------------------------------- The drive's DC power can be applied to either section A or B. The IDE-bus interface (40-pin) uses section C.

IDE-Bus Interface Connector (J11C) ---------------------------------- On the ProDrive LPS 210/420AT hard disk drive, the IDE-bus interface cable connector (J11 section C) is a 40-pin Universal Header. To prevent the possibility of incorrect installation, make sure the connector is keyed by removing Pin 20. Removing this pin ensures the connector cannot be installed upside down. For mating with J11 section C, recommended cable connectors include the following parts or their equivalents: AMP receptacle with strain relief P/N 1-499506-0 AMP receptacle without strain relief P/N 1-746193-0 To key the cable connector, you must plug the hole that corresponds to pin 20. Other recommended part numbers for the mating connector include: 40-Pin Connector 3M 3417-7000 or equivalent Strain Relief 3M 3448-2040 or equivalent Flat Cable (Stranded 28 AWG) 3M 3365-40 or equivalent Flat Cable (Stranded 28 AWG) 3M 3517-40 (shielded) or equivalent J12 LED Connector ----------------- The LED connector may be used to connect an external LED for the purpose of monitoring drive activity. A 220-ohm resistor is connected in series from the +LED pin to +5 volts. The -LED pin is connected to a switching transistor on the drive that turns on and lights the LED when the disk is performing a read or write operation. When no read or write operation is taking place, the transistor turns off and the LED is extinguished. The recommended mating connector parts are: Two-position housing: Molex P/N 51021-0200, Loose-piece contacts: Molex P/N 50058-8100, or equivalent. Pin 1 -LED, Pin 2 +LED. For Systems with a Motherboard AT Adapter ========================================= You can install the ProDrive LPS 210/420AT hard disk drive in an AT-compatible system that contains a 40-pin AT-bus connector on the motherboard. To connect the drive to the motherboard, use a 40-pin ribbon cable. Ensure that pin 1 of the drive is connected to pin 1 of the mother- board connector. For Systems with an IDE Adapter Board ===================================== To install a ProDrive LPS 210/420AT hard disk drive in an AT- compatible system without a 40-pin, IDE-bus connector on its motherboard, you need a third-party IDE-compatible adapter board. Adapter Board Installation -------------------------- Carefully read the manual that accompanies your adapter board before installing it. Make sure that all the jumpers are set properly and that there are no addressing or signal conflicts. You must also investigate to see if your AT-compatible system contains a combination floppy and hard disl controller board. If it does, you must disable the hard disk drive controller functions on the controller board before processing. Once you have disabled the hard disk drive controller functions on the floppy/hard drive controller, install the adapter board. Again, make sure that you have set all jumper straps on the adapter board to avoid addressing and signal conflicts. Connecting the Adapter Board and the Drive ------------------------------------------ Use a 40-pin ribbon cable to connect the drive to the board. 1. Insert the 40-pin cable connector into the mating connector of the adapter board. Make sure that pin 1 of the connector matches with pin 1 on the cable. 2. Insert the other end of the cable into the header on the drive. When inserting this end of the cable, make sure that pin 1 of the cable connects to pin 1 of the drive connector. 3. Secure the drive to the system chassis by using the mounting screws. Electrical Characteristics -------------------------- All signals are transistor-transistor logic (TTL) compatible - with logic 1 greater than 2.0 volts and less than 5.25 volts; and logic 0 greater than 0.2 volts and less than 0.8 volts. Neither the adapter board, motherboard interface, or drives require terminating resistors. Air Filtration -------------- The ProDrive LPS 210/420AT hard disk drives are Winchester-type drives. The heads fly very close to the media surface. Therefore, it is essential that the air circulating within the drive be kept free of particles. Quantum assembles the drive in a Class-100, purified air environment, then seals the drive with a metal cover. When the drive is in use, the rotation of the disks forces the air inside the drive through an internal filter. The highest air pressure within the HDA is at the outer perimeter of the disks. A constant stream of air flows through a 0.3-micron circulation filter positioned in the base casting. ********************************************************************** F E A T U R E S ********************************************************************** QUANTUM PRODRIVE LPS 210/420AT PRODUCT MANUAL 81-106898-02, JUNE 94 General Description ------------------- Quantum's ProDrive Low Profile Series (LPS) 210AT/420AT hard disk drives are a part of a family of high-performance, 1-inch-high hard disk drives manufactured to meet the highest product quality standards. ProDrive LPS hard disk drives use nonremovable, 3 -inch hard disks, and are available with a Small Computer System Interface (SCSI) or Advanced Technology (AT) interface. The ProDrive LPS 210AT/420AT hard disk drives feature an embedded IDE drive controller and use ATA commands to optimize systems performance. The drive manages media defects and error recovery internally, these operations are transparent to the user. Seek Times ---------- +------------------+--------------+ |Track-to-track | 5 ms typ. | +------------------+--------------+ |Average seek | 15 ms typ. | +------------------+--------------+ |Full stroke | 31 ms typ. | +------------------+--------------+ |Rotational Latency| 8.33 ms | +------------------+--------------+ System Startup and Operation ---------------------------- Once you have installed the ProDrive LPS 210/420AT hard disk drive and adapter board (if required) in the host system, you are ready to partition and format the drive for operation. To set up the drive correctly, follow these steps: 1. Power on the system 2. Run the SETUP program. This is generally on a Diagnostics or Utilities disk, or within the system's BIOS. 3. Enter the appropriate parameters. The SETUP program allows you to enter the types of optional hard- ware installed - such as the hard disk drive type, the floppy disk drive capacity, and the display adapter type. The system's BIOS uses this information to initialize the system when the power is switched on. For instructions on how to use the SETUP program, refer to the system manual for your PC. During the AT system CMOS setup, you must enter the drive type for the ProDrive LPS 210/420AT hard disk drive. This procedure allows the system to recognize the drive by translating its physical drive parameters such as cylinders, heads, and sectors per track, into a logical addressing mode. The drive can work with different BIOS drive-type tables of the various host systems. You can choose any drive type that does not exceed the capacity of the drive. 4. Boot the system using the operating system installation disk. Formatted Capacity ------------------ At the factory, the ProDrive LPS 210/420AT receives a low-level format that creates the actual tracks and sectors on the drive. Data Transfer Rates ------------------- Data is transferred from the disk to the read buffer at a rate up to 3.945 MB/s in burst. Data is transferred from the read buffer to the AT bus at a rate up to 6.0 MB/s, using programmed I/O. If IORDY is used, then this transfer rate can be increased to 11 MB/s. Using the Multiword DMA protocol, transfer rates of 13.3 MB/s. are achievable (burst mode only). Reliability ----------- Mean Time Between Failures (MTBF): 300,000 Power On Hours (POH), typical usage Component Life: 5 years Preventive Maintenance (PM): Not required Start/Stop: 20,000 cycles (minimum) The Quantum MTBF numbers represent Bell-Core MTBF predictions and represent the minimum MTBF that Quantum or a customer would expect from the drive. Error Detection and Correction ------------------------------ As disk drive areal densities increase, obtaining extremely low error rate requires a new generation of soghisticated error-correction codes. Quantum ProDrive LPS 210/420AT series hard disk drives implement 112-bit single- and double-burst Reed-Solomon error correction techniques to reduce the uncorrectable read error rate to less than one bit in 1 x 10(14) bits read. When errors occur, an automatic retry and a more rigorous double- burst correction algorithm enable the correction of any sector with two burst of three incorrect bytes each or up to six multiple random one-byte burst errors. In addition to these advanced error correction capabilities, the drive's additional cross-checking code and algorithm double checks the main ECC correction to greatly reduce the probability of miscorrection. Automatic Actuator Lock ----------------------- To ensure data integrity and prevent damage during shipment, the drive uses a dedicated landing zone and Quantum's patented AIRLOCK. AIRLOCK, locks the headstack in the landing zone. It consists of an air vane mounted near the perimeter of the disk stack and a locking arm that restrains the actuator arm assembly. When DC power is applied to the motor and the disk stack rotates, the rotation generates an airflow on the surface of the disk. As the flow of air across the air vane increases with disk ratation, the locking arm pivots away from the actuator arm, enabling the headstack to move out of the landing zone. When DC power is removed from the motor, an electric return mechanism automatically pulls the actuator into the landing zone, where the AIRLOCK holds it in place. Disk Caching ------------ The ProDrive LPS 210/420AT hard disk drive incorporates DisCache, a 96K disk cache, to enhance drive performance. This integrated feature can significantly improve system throughput. Read and write caching can be enabled or disabled by using the SET CONIGURATION command. Defect Management ----------------- The ProDrive LPS 210/420AT allocates one sector per cylinder as a spare. In the factory, the media is scanned for defects. If a sector on a cylinder is found to be defective, the address of the sector is added to the drive's defect list. Sectors located physically subsequent to the defective sector are assigned logical block addresses such that a sequential ordering of logical blocks results. This inline sparing technique is employed in an attempt to eliminate slow data transfer that would result from a single defect- ive sector on a cylinder. If more than one sector is found defective on a cylinder, the inline sparing technique is applied only to the first sector. The remaining defective sectors are replaced with the nearest available spare sectors on nearby cylinders. Such an assignment of additional replacement sectors from nearby sectors rather than having a central pool of spare sectors is an attempt to minimize the motion of the actuator and head that otherwise would be needed to find a replace- ment sector. The result is minimal reduction of data throughput. Track and Cylinder Skewing -------------------------- Track and cylinder skewing in the ProDrive LPS 210/420AT minimizes latency time and thus increases data throughput. Track Skewing ------------- Track skewing reduces the latency time that results when the drive must switch read/write heads to access sequential data. A track skew is employed such that the next logical sector of data to be accessed will be under the read/write head once the head switch is made and the data is ready to be accessed. Thus, when sequential data is on the same cylinder but on a different disk surface, a head switch is needed but not a seek. Since the sequential head-switch time is well defined on the ProDrive LPS 210/420AT (6 ms worst case), the sector addresses can be optimally positioned across track boundaries to minimize the latency time during a head switch. Cylinder Skewing ---------------- Cylinder Skewing also is used to minimize the latency tome associated with a single-cylinder seek. The next logical sector of data that crosses a cylinder boundary is positioned on the drive such that after a single-cylinder seek is performed, and when the drive is ready to continue accessing data, the sector to be accessed is positioned directly under the read/write head. Therefore, the cylinder skew takes place between the last sector of data on the last head of a cylinder and the first sector of data on the first head of the next cylinder. Since single-cylinder seeks are well defined on the ProDrive LPS 210/420AT, the sector addresses can be optimally positioned across cylinder boundaries to minimize the latency time associate with a single-cylinder seek. Error Reporting --------------- At the start of a command's execution, GoDrive 40/80AT hard disk drives check the COMMAND register for any conditions that would lead to an abort command error. The drive then attempts execution of the command. Any new error causes execution of the command to terminate at the point at which it occurred. The following table list the valid errors for each command. -----------------+--------------------------+---------------------+ COMMAND |ERROR REGISTER |STATUS REGISTER | +--------------------------+---------------------+ |BBK|UNC|IDNF|ABRT|TK0|AMNF|DRDY|DWF|DSC|CORR|ERR| -----------------+---+---+----+----+---+----+----+---+---+----+---+ Check Power Mode | | | | V | | | V | V | V | V | V | Read Defect List | V | V | V | V | | V | V | V | V | V | V | Exec.
