The CS and DS jumpers cannot be installed at the same time In ProDrive 40/80AT mode, neither diagnostics commands nor soft resets set the Drive Select bit in the AT interface to zero. CS Cable Select Jumper ----------------------- When two ProDrive LPS 120/240AT hard disk drives are daisy-chained together, they can be configured as a Master or a Slave either by the CS or DS jumpers. Only one jumper may be used at a time. To configure the drive as a Master or Slave with the CS jumper, the CS jumper is installed and the DS jumper is removed. Once you install the CS jumper, the drive is configured as a Master or Slave by the state of the Cable Select signal - pin 28 at the AT- bus connector. Please note that pin 28 is a vendor-specific pin that Quantum is using for a specific purpose, and does not conform to the function normally allocated for this pin according to the ATA CAM specification. If pin 28 is 0 (grounded), the drive is configured as a Slave. If it is a 1 (high), the drive is configured as a Master. In order to configure two drives in a Master/Slave relationship using the CS jumper, you need to use a cable that provides the proper signal level at pin 28 of the AT bus connector. DS Drive Select Jumper ----------------------- x CLOSED Single drive or MASTER (Drive 0) OPEN SLAVE (Drive 1) Note: The order in which drives are connected in a daisy chain has no significance. You can also daisy-chain two drives on the AT-bus interface by using their Drive Select (DS) jumpers. If the DS jumper is installed, the CS jumper must be removed. SP Slave Present Jumper ------------------------- In combination with the current DS or CS jumper settings, the Slave Present jumper implements one of two possible configuratons: When the drive is configured as a Master - that is, with the DS jumper installed or with the CS jumper installed and the Cable Select signal set to 0 (grounded) - the SP jumper should be installed on the Master drive only if the Slave drive does not use the Drive Active/Slave (DASP-) signal to indicate its presence. When the drive is cnfigured as a Slave - that is, without the DS jumper installed - the SP jumper enables the self-seek test. When power is applied to the drive with the self-seek test enabled, the drive executes seeks in a butterfly pattern. If an error is encountered during the self test, the test terminates. DM Drive Mode Jumper --------------------- When the drive mode jumper is installed, the drive is in the ProDrive 40/80AT-compatible mode and can communicate with a ProDrive 40/80AT hard disk drive. In this mode, the drive does not use the PDIAG- signal to control Master/Slave communications. The configuration of the DS, CS, and SP jumpers determines whether the drive is the Master or the Slave.

Pins 2 and 3 are connected on the drive. --------------------------------------------------------------------- Adapter Board Jumper Options ============================ Four jumper pins on the adapter board - labeled J2 through J5 - have the function described below. J2 Enables the drive's interrupt logic to control IRQ14 (Interrupt Request 14). This option provides compatibility with systems in which the BIOS does not read the STATUS Register when the drive issues an interrupt. In such cases, the drive might fail to transmit the interrupt to the system. - A jumper from the center pin J2 to E3 enables transmission of an interrupt every time the drives goes busy. - A jumper from the center pin J2 to E4 gates the interrupt from the drive and transmits it directly to the AT bus. This is the default setting. J3 This jumper should always remain off. J4 This jumper should generally remain off. A jumper should be installed here only when installing the adapter board in a system that uses the Chips & Technologies chip set. This chip set runs the I/O bus faster than the standard 12 Mhz, one wait state. J5 Enables secondary interface selection on a second adapter board installed in a system. When a jumper is installed here, drives connected to the adapter board respond to commands transmitted via the secondary address, 170H-177H. Standard BIOS versions do not support secondary addresses. Therefore, you must write a custom driver to implement a secondary interface. Note: A second adapter board is supported only when both adapter boards are Quantum boards. ********************************************************************** I N S T A L L ********************************************************************** QUANTUM PRODRIVE LPS 120/240AT PRODUCT MANUAL 803-20-9314 Notes on Installation ===================== Mounting -------- The mounting holes on the ProDrive LPS 120/240AT hard disk drive allow the drive to be mounted in any orientation. For mounting #6-32 UNC screws are recommended. 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 0.10 inches minimum. Ventilation ----------- The LPS 120/240AT hard disk drives operates without a cooling fan, provided the ambient air temperature does not exceed 131*F (55*C). J1 AT-Bus Interface Connector ----------------------------- On the ProDrive LPS 120/240AT hard disk drive, the AT-bus interface cable connector (J1) is a 40-pin Universal Header. To prevent the possibility of incorrect installation, you should make sure that the connector is keyed by removing pin 20. Removing this pin will ensure that the connector cannot be installed upside down. For the mating J1 connector, recommended cable connectors include AMP receptacle P/N 1-499506-0, with strain relief; P/N 1-746193-0, with- out strain relief; or an equivalent. To key the cable connectors, you must plug the hole that correspond 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 For Systems with a Motherboard AT Adapter ========================================= You can install the ProDrive LPS 120/240AT 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 a Adapter Board ================================ To install a ProDrive 120/240AT hard disk drive in an AT-compatible system without a 40-pin, AT-bus connector on its motherboard, you need a ProDrive AT-Bus Adapter Kit (P/N 900-009002). The adapter kit includes an adapter board and a ribbon cable, which is used to connect the board to the drive. THIS SECTION OF THE DESCRIPTION PERTAINS ONLY TO SYSTEMS THAT REQUIRE THE ADAPTER KIT. Adapter Board Installation -------------------------- The adapter board is a half-size board. You can install it in any available 16-bit slot in an IBM PC-AT or compatible personal computer. Before installing the adapter board, make sure that no other hard drive controller resides at the primary hard drive address, 1F0H-1F7H, and that the jumpers are set properly. If a combination floppy and hard disk drive controller is present, you must disable the hard disk drive controller functions on the disk drive controller. To disable the hard disk drive controller functions, follow these instructions: On a Western Digital WD1002-WA2 or WD1003-WA2 floppy/hard disk drive controller card: - Install jumpers on pins E4 and E5 to ensure that the controller card resides at the secondary address, 170H-177H, rather than at the primary address, 1F0H-1F7H. Do not install jumpers on pins E5 and E6. - Move the card from a 16-bit I/O slot to an 8-bit slot to disconnect the IRQ14 output driver. On a Data Technology Corporation (DTC) floppy/hard disk drive controller card: - Install a jumper on pins W3. - To disconnet the IRQ14 output driver, move the ard from a 16-bit I/O slot to an 8-bit slot. Once you have disabled hard disk drive controller functions on the floppy/hard drive controller, install the adapter board in a 16-pin slot. Connecting the Adapter Board and the Drive ------------------------------------------ Use the ribbon cable supplied with the adapter board to connect the drive to the board. 1. Insert the cable connector into the header on the adapter board. Note the number 1 printed on the board next to the header. When inserting the cable, make sure the red wire on the cable is at the side of the header labeled 1. 2. Insert the other end of the cable into the header on the drive. When inserting this end of the cable, make sure the red wire on the cable is at the inside edge of the header, next to the J3 power connector. 3. Secure the drive to the system chassis by using the mounting screws. J3 DC Power Connector --------------------- The DC power connector is a 4-pin Ranoda Electronics Connector (06300010-04-1) mounted on the back edge of the Printed Circuit Board (PCB). Recommended part numbers for the mating connector are: 4-pin connector AMP P/N 1-480424-0 or equivalent Loose-piece contacts AMP P/N 61173-4 or equivalent Strip contacts AMP P/N 350078-4 or equivalent Air Filtration -------------- Low Profile Series hard drives are Winchester-type drives. The heads fly very close to the media surface, at a nominal flying height of 4 microinches. 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, sealing the drive mechanism under a metal cover. When the drive is in use, the rotation of the disks forces the air inside the drive through an internal filter. Electrical Characteristics -------------------------- All signals are TTL-compatible - with logic one greater than 2.0 volts and less than 5.25 volts; and logic zero, greater than 0.0 volts and less than 0.7 volts. Neither the adapter board nor the drives require terminating resistors. Adapter Board Interface Characteristics --------------------------------------- Each Adapter Board can support one or two hard drives. There is a maximum of two adapter boards, which will support four drives. When more than one drive is present, a master/slave relationship exists between the two drives. The host always maintains control of the bus - no arbitration occurs. Disk Caching ------------ The ProDrive LPS 120/240AT hard disk drive incorporates DisCache, a 256K disk cache, to enhance drive performance. This integrated feature cam be programmed by means of the SET CONFIGURATION or SET FEATURES commands, and can significantly improve system throughput. Some of the cache can be configured n real time meet overall system requirements. ********************************************************************** F E A T U R E S ********************************************************************** QUANTUM PRODRIVE LPS 120/240AT PRODUCT MANUAL 803-20-9314 General Description ------------------- Quantum's ProDrive Low Profile Series (LPS) 120AT and 240AT 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 120/240AT hard disk drives feature an embedded AT drive controller and use AT commands to optimize systems performance. Because the drive manages media defects and error recovery internally, these operations are fully transparent to the user.

Seek time is measured by averaging 1000 of random seeks. Preventive Maintenance ---------------------- The ProDrive LPS 120/240AT hard disk drive requires no preventive maintenance. Data Transfer Rates ------------------- Data is transferred from the disk to the read buffer at a rate of 3.75 MB/s maximum, 1.87 MB/s minimum. Data is transferred from the read buffer to the AT Bus at a rate of up to 5.0 MB/s, using programmed I/O. Formatted Capacity ------------------ At the factory, the LPS 120/240AT receives a low-level format that creates the actual tracks and sectors on the drive. Formatting done at the user level, for operation with DOS, UNIX, or other operating systems, will result in less capacity than the physical capacity shown below. LPS 120AT LPS 240AT Formatted capacity 122 MB 245 MB Number of 512-byte sectors 238,766 479,350 Note: As defined by Quantum, 1 megabyte (MB) is 1,000,000 bytes. Write Precompensation --------------------- The write-precompensation circuit reproduces the write data pulse with either an advance (EARLY) or delayed (LATE) programmable time with respect to the time spacings of the rising edges of WRDATA. The amount of advance or delay time is programmable from 1 to 8 ns. Defect Management ----------------- The ProDrive LPS 120/240AT 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 defects list. Sectors located physically sub- sequent to the defective sector assigned logical block addresses such that a sequential ordering of logical blocks result. This inline sparing technique is employed in an attempt to eliminate slow data transfers which would result from a single defective sector on a cylinder. Error Correction Code and ECC On-The-Fly ---------------------------------------- The ProDrive LPS 120/240AT hard disk drive implements 96-bit single and double burst Reed-Solomom error correction techniques. Single burst errors of up to to 24 bits within one sector can be corrected "on-the-fly", in real time as they occur, allowing a high degree of data integrity with no impact to the drive's performance. The drive does not need to re-read sector on the next disk revolu- tion or apply ECC for those errors that are corrected on-the-fly. Errors corrected in this manner are invisible to the host system. When errors cannot be corrected on-the-fly, an automatic retry and a more rigorous double burts error correction algorithm enable the correction of any sector with two burst of three incorrect bytes each or up to 6 multiple random one-byte burst errors. In addition to this error correction capability, the drive's implementation of an additional cross-checking code and algorithm double checks the main ECC correction and greatly improves the probability of miscorrection. 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 sector on nearby cylinders. Such an assignment of additional replace- ment 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 which would be otherwise needed to find a replace- ment sector. The result in minimal reduction of data throughput. Track Formatting ---------------- The LPS 120/240AT hard disk drive is shipped from the factory with all of the physical sector addresses prewritten on the surface of the disk. As a result, the number of bytes per sector and the number of sectors per track are not selectable by the user.
