The SP is labeld "SP" for slave present. The other set (three jumper pins) has two labels "CS" and "DS" for Cable Select and Drive Select. The center pin is common to both the CS and the DS positions. When a jumper block is on the center pin and the pin nearest the interface connector, DS is enabled. When a jumper block is on the center pin and the pin furthest from the interface connector, CS is enabled. NOTE Jumper blocks can be placed in a storage position by locating them on one jumper pin as shown in the following Figure. +-++-+ +-++-++-+ ++++++Pins +++++++++ Pins SP DS CS +*--*+ +*--*+ +----+Jumper +----+Jumper Master Drive Configuration -------------------------- GoDrive 40/80 AT hard disk drives are configured at the factory as a master drive as defined by the CAM (Common Access Method). This configuration is shown in the following figure. +-++-+ +-++-++-+ ++++++Pins +++++++++ Pins SP DS CS +*--*+ +*--*+ +----+Jumper +----+Jumper Master Drive with Slave Present ------------------------------- When GoDrive 40/80 AT hard disk drives are configured as a master drive, the drive looks for a slave drive by monitoring the PDIAG/DASP lines. Some hard disk drives when configured as a slave do not indicate their presense on these two lines (GoDrive does). To indicate that a slave is present for these drive (when using GoDrive as a master), the slave present (SP) pins on GoDrive master must be jumpered as shown. +-++-+ +-++-++-+ ++++++Pins +++++++++ Pins SP DS CS +*--*+ +*--*+ +----+Jumper +----+Jumper Slave Drive Configuration ------------------------- GoDrive drives can be configured as a slave drive as shown. +-++-+ +-++-++-+ ++++++Pins +++++++++ Pins SP DS CS +*--*+ +*--*+ +----+Jumper +----+Jumper Cable Selection --------------- The drive can be configured such that its status as a master or slave drive can be determined by the cabling from the host system. +-++-+ +-++-++-+ ++++++Pins +++++++++ Pins SP DS CS +*--*+ +*--*+ +----+Jumper +----+Jumper NOTE This is extremely helpful when GoDrive 40/80 AT is used as a removable subsystem where it can be either master drive or a slave drive depending upon the cable to which is connected. When the GoDrive is configured for cable selection, as shown in the Figure below, it is the master drive if Pin 28 is grounded and a slave if Pin 28 is not grounded. For systems that do not use Pin 28 for another purpose (e.g., Address Latch Enabled), the host system can tie Pin 28 to ground. Then the cable connecting the host to the master has Pin 28 enabled (i.e., a circuit exists), while the cable connecting the slave to either the host or the master has the Pin 28 line servered. Systems that use Pin 28 can use the cable selection method by performing the following: 1. Connect the system cable in the following order host <--> slave <--> master. 2. Cut the Pin 28 line between the slave and the master. This allow Pin 28 to operate normally (an open - served connection) between the host and the slave. 3. Tie Pin 28 (within the master drive header) to a nearby ground (Pin 30, for example). This process will allow the master drive to have Pin 28 grounded while allowing the Pin 28 to be open between the host and slave drive. ********************************************************************** I N S T A L L ********************************************************************** QUANTUM GODRIVE 40/80AT PRODUCT MANUAL REVISION 1.0 803-20-9303 Notes on Installation ===================== Installation direction ---------------------- horizontally vertically +-----------------+ +--+ +--+ | | | +-----+ +-----+ | | | | | | | | | +-+-----------------+-+ | | | | | | +---------------------+ | | | | | | | | | | | | | | | | | | +---------------------+ | +-----+ +-----+ | +-+-----------------+-+ +--+ +--+ | | | | +-----------------+ Dimensions and Mounting ----------------------- The drive can be mounted in any orientation. Maximum screw length is 3mm with three minimum full threads. The maximum mounting torque for these screws is 120 inch-ounces. NOTE If the bottom mounting holes are used, the mating surface of the assembly that attaches to the bottom must have a flatness of 0.076mm (0.003 inches) or better. Ventilation ----------- GoDrive 40/80AT hard disk drives can operate without a cooling fan, provided the ambient air temperature des not exceed 55*C (131*F). Any user-designed cabinet must provide adequate air circulation to prevent the maximum temperature from being exceeded. Cable Connector --------------- GoDrive 40/80AT hard disk drives have a single 2 x 22 connector (on 2mm centers) for both power and data. The connector also includes four pins which are reserved for factory test points. The recommended system mating connector is a Dupont part number 69764-044 or equivalent. The maximum cable length is 18 inches. To assure that the system cable connector is installed with the proper orientation, plug the Pin 20 hole on the system connector. | Pin 1 | | +------------------------------------------+------+ | | |o o o o o o o o o o o o o o o o o o o o o o o o| | | ++o o o o o o o o o o o o o o o o o o o o o o o++ | | |++-----------------------+-----------------+------+| | | | Pin 44 Pin 20 Pin 2 | | +---+ +---+ Power Sequencing ---------------- GoDrive 40/80AT hard disk drives require no power sequencing. Applying or removing power during drive operation does not cause data to be lost or corrupted. Although the drive requires no power sequencing, Quantum recommends that is a controlled power dwon is available from the system (e.g., in a system with an auto resume feature), a Standby command should be issued to the drive prior to the removal of power. CAUTION Data may be lost or corrupted in a sector being written at the time of a power loss. During power-on or power-off, the drive can sustain an open or a short circuit on either the voltage or the return line. Electrical Interface -------------------- All signals are TTL-compatible. A logic one is greater than 2.0 volts and less than 5.25 volts. Logic zero is greater than 0.0 volts and less than 0.7 volts. The drive requires no terminating resistors. ********************************************************************** F E A T U R E S ********************************************************************** QUANTUM GODRIVE 40/80AT PRODUCT MANUAL REVISION 1.0 803-20-9303 General Description ------------------- Quantum's GoDrive 40AT and GoDrive 80AT hard disk drives are part of a family of high performance, 2.5-inch form factor hard disk drives manufactured to meet the highest product-quality standards. GoDrive 40/80AT hard disk drives feature an embedded AT drive controller and uses AT commands to optimize system performance. Be- cause the drive manages media defects and error recovery internally, these operations are fully transparent to the user. Note: The GoDrive 40/80AT does not include a faceplate! Features -------- - Low-profile, optimized for number of disks - Data-transfer rate of up to 4.0 megabyte per second, using programmed I/O - Proprietary 32K, look-ahead, programmable DisCache with WriteCache (8K on the GoDrive 40AT) - 112-bit Reed Solomon Error Correction Code (ECC), with 48-bit double burst correction - Automatic retry on read errors - Transparent media-defect mapping - High performance, in-line defective sector skipping - Reassignment of defective sectors discovered in the field, without reformatting - Automatic actuator shipping lock and dedicated landing zone - Emulation of IBM PC/AT task file register and all AT fixed-disk commands - Ability to daisy-chain two drives on the interface Seek Time --------- +-------------------------------+--------+ |Track-to-Track msec. typ. | 5 | +-------------------------------+--------+ |Average msec. typ. | 19 | +-------------------------------+--------+ |Full-Stroke msec. | 30 | +-------------------------------+--------+ |Latency msec. avg. | 8.3 | +-------------------------------+--------+ 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|TK0NF|AMNF|DRDY|DWF|DSC|CORR|ERR| -----------------+---+---+----+----+-----+----+----+---+---+----+---+ Defect List | | V | V | V | | | V | V | V | V | V | Exec.

In the factory, the media is scanned for defects. If a sector on a cylinder found to be defective, the sector's address is added to the drive's defect list. Sectors physically subsequent to the defective sector are assigned logical block addresses such that a sequential ordering of logical blocks results. This in-line sparing technique is employed in an attempt to eliminate throughput reduction resulting from a single defective sector on a cylinder.
