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 ELS 42/85/127/170AT 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 as a vendor-specific pin; it does NOT conform to the function normally allocated for this pin according to the ATA (AT Attachment). 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 ELS 42/85/127/170AT 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 ELS 42/85/127/170AT. J41A/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.

Mounting -------- Drive mounting orientation, clearance, and ventilation requirements are described in the following subsections. For mounting, #6-32 UNC screws are recommended. To avoid stripping the mounting-hole threads, the maximum torque applied to the screws must not exceed 8 inch- pounds. Drive Installation ------------------ You can install the ProDrive ELS 42/85/127/170AT hard disk drive in an AT-compatible system in two ways: - To install the drive on a motherboard that contains a 40-pin IDE- bus connector, connect the drive to the motherboard using a 40-pin ribbon cable. Ensure that pin 1 of the drive is connected to pin 1 of the motherboard connector. - To install the drive in a system without a 40-pin, IDE-bus connector on its motherboard you need an IDE-bus adapter kit. The adapter kit includes an adapter board and a ribbon cable, which is used to connect the board to the drive. Clearance --------- The printed-circuit board assembly (PCBA) is very close to the mounting holes. Clearance from the drive to any other surface - except mounting surfaces - must be 3.5 millimeters (0.14 inches) minimum. The specified screw length allows full use of the mounting- hole threads, while avoiding damaging or placing unwanted stress on the PCBA. Ventilation ----------- The ProDrive ELS 42/85/127/170AT hard disk drives operates without a cooling fan, provided the ambient air temperature does not exceed 122*F (50*C). DC Power (J41 A and B) ---------------------- The recommended mating connectors for the +5VDC and +12VDC input power are listed above. J41A 4-Pin Connector: AMP P/N 1-480424-0 Loose piece contacts: AMP P/N 61173-4 Strip contacts: AMP P/N 350078-4 J41B 3-Pin Connector: Molex P/N 39-01-0033 Loose piece contacts: Molex P/N 39-00-00341 Strip contacts: Molex P/N 39-00-0023 Labels indicates the pin numbers on the connectors. IDE-Bus Interface Connector (J41C) ---------------------------------- On the ProDrive ELS 42/85/127/170AT hard disk drive, the IDE-bus interface cable connector (J41 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 J41 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 AT Interface Controller ----------------------- The AT Interface Controller portion of the DCAIA provides data handling, bus control, and transfer management services for the IDE interface. It is capable of data transfer rates of up to 4 MB/s. Configuration and control of the interface is accomplished by the Controller across the MAD bus. Data transfer operations are controlled by the DCAIA Buffer Controller module. Disk Caching ------------ The ProDrive ELS 42/85/127/170AT hard disk drive incorporates DisCache, a 32K (8K for the 42AT) disk cache, to enhance drive performance. This integrated feature can significantly improve system throughput. Read and write caching can be enabled or disabled using the SET CONFIGURATION command.

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. 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. 3. Enter the appropriate parameters. During the AT system CMOS setup, you must enter the drive type for the ProDrive ELS 42/85/127/170AT hard disk drive. This procedure allows the system to recognize the drive by translating its physical drive geometry oarameters such as cylinders, heads, and sectors per track, into a logical addressing mode. ProDrive ELS 42/85/127/170AT drives can work with different BIOS drive-type tables of various host system. You can choose any drive type that does not exceed the capacity of the drive. +----------------------------------------------+ |Logical Addressing Format | +---------------------+-----+-----+------+-----+ | |42AT |85AT |127AT |170AT| +---------------------+-----+-----+------+-----+ |Logical Cylinders | 968 | 977 | 919 | 1011| |Logical Heads | 5 | 10 | 16 | 15| |Logical Sectors/Track| 17 | 17 | 17 | 22| +---------------------+-----+-----+------+-----+ 4. Boot the system using the operating system installation disk. Formatted Capacity ------------------ At the factory, the ProDrive ELS 42/85/127/170AT 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 2.5MB/s in burst. Data is transferred from the read buffer to the AT bus at a rate up to 4.0 MB/s, using programmed I/O.

Quantum's ongoing reliability testing and field return data has historically confirmed an actual MTBF of twice the Bell-Core prediction. 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 ELS 42/85/127/170AT 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.
