A 1996 Jumper Setting ============== Master/Slave Configuration -------------------------- When two drives are daisy-chained on the host interface, one must be designated as the master drive (C: drive) and one as the slave drive (D: drive). Commands from the host are written in parallel to both drives. When the C/D jumper on the drive is closed, the drive will assume the role of a master. When C/D is open, the drive will act as a slave. In single-drive configurations, C/D must remain in the closed (master) position. For each command sent from the host, the DRV bit in the Device/Head register selects the master or the slave drive. When the DRV bit is reset (0), the master drive is selected, and when the DRV bit is set (1), the slave drive is selected. Once the drives receive the command, only the drive with jumper C/D set to the appropriate position will execute the command. For example, if the DRV bit is set, only the slave drive (jumper C/D open) will execute the command. Note: If the command is a diagnostic command, both drives will execute the command and the slave will report its status to the master via the Host PDIAG signal. Throughout this manual, drive selection always refers to the state of the DRV bit and the position of the C/D jumper. Cable Select ------------ This optional method of drive Master/Slave designation can be enabled by jumper selection. If used, special cabling can be used to selectively ground CSEL of the drive intended to be drive C (0). This drive will then function as the Master. If CSEL is allowed to float the drive will recognize itself as drive D (1) and function as the Slave. Pins: Signal: Description 1 and 2 C/D Open: Drive will act as drive 1. Closed: Drive will act as drive 0. 3 and 4 AC Open: Drive will report 4160 cylinders. Closed: Drive will report 4095 cylinders 5 and 6 Note: CS Open: Cable select option disabled Closed: Cable Select enabled When using C/S option, the C/D jumper must be open 7 to 18 N/A Reserved ********************************************************************** I N S T A L L ********************************************************************** CONNER CFA-2161 FILEPRO PRODUCT MANUAL REV.

What is the Drive? ------------------ The Conner Filepro Advantage CFA2161A is a high-performance, low-profile hard disk drive which is designed to operate with an IBM PC/AT or equivalent host computer system in translate mode. The drive supports advanced ATA PIO Mode 4 and DMA Mode 2 data transfer protocols for superior I/O performance. Logical Block Addressing (LBA) is supported for compatibility with advanced systems (BIOS) which support greater than 528MB capacity IDE drives, as well as Cylinder-Head-Sector (CHS) addressing for backward compatibility. Features of the Drive --------------------- The drive provides these features: - Task File emulation and ATA compatibility allows installation in a wide range of host systems. - high-performance rotary voice coil actuator with embedded servoing eliminates the need for T-cal - one-of-seven run-length limited code - high shock resistance - automatic actuator latch against inner stop upon power-down - microprocessor-controlled diagnostic routines that are automatically executed at start-up - 128KB segmentable cache buffer - Read Look Ahead and Write Caching - automatic error correction and retries, single burst ECC on the fly - supports ATA Standard PIO Mode 4 and DMA Mode 2 - 512-byte block size - supports both CHS and LBA addressing - allows daisy-chaining up to two drives on the AT interface - Auto-Translate (Universal Translate) - 11-byte ECC diagnostic check in read/write Head-Disk Assembly ------------------ The Head-Disk Assembly (HDA) is housed within a die-cast aluminum base on which is mounted a die-cast aluminum cover. Both the base and the cover are manufactured using a corrosion resistant alloy. A gasket seals the joint between the base and cover to retard the entry of moisture and environmental contaminants from the assembly. This assembly, the head-disk assembly, contains an integral 0.3 micron filter, carbon adsorber module and breather filter, which maintain a clean environment. Critical drive components are contained within this contaminant-free environment. Drive Motor and Spindle ----------------------- A brushless DC direct-drive motor assembly is mounted on the drive's base. The motor rotates the drive's spindle at 5400 RPM. The motor/spindle assembly is dynamically balanced to provide minimal mechanical runout to the disks. A dynamic brake is used to provide a fast stop to the spindle motor and return the heads to the landing zone when power is removed. Head Positioning Mechanism -------------------------- The read/write heads are supported by a mechanism coupled to a rotary voice coil actuator. Read/Write Heads and Disks -------------------------- Data is recorded on 95mm diameter disks through thin film heads. The CFA2161A contains four disks and eight read/write heads. At power-down, the heads are automatically retracted to the inner diameter of the disk and are latched and parked on a landing zone that is inside the data tracks. Data and Power Connections -------------------------- The drive has a single 40-pin data connector, as well as an auxiliary connector which is reserved for factory or evaluation use. The drive has a standard 4-pin power connector and may optionally have a 3-pin connector, only one of which should be used at a time. The drive also has a jumper block located next to the auxiliary connector which can be set to specify drive operational parameters. For more information on the drive's connectors and on setting jumpers. Electrical Design Features -------------------------- Integrated Circuit A single integrated circuit (IC) is mounted within the sealed hard drive assembly in close proximity to the read/write heads. The IC provides head selection, read pre-amplification, and write drive circuitry. Circuit Board ------------- The drive's microprocessor-controlled circuit board provides the remaining electronic functions, which include: - read/write circuitry - rotary actuator control - interface control - spin speed control - auto-park - power management Firmware -------- The drive's firmware includes a command set which the host uses to control the drive. The command set allows the host to request the following types of actions: - report drive status (SMART) - seek a specific point on the disk - read and write data Acoustic Noise: --------------- - The acoustic sound power level measured based on ISO7779 is typically 4.0 Bel and will not exceed 4.5 Bel in Idle Mode. Product Test Standards ---------------------- The drive is designed to comply with relevant product safety standards, including: - UL 478, 5th edition, Standard for Safety of Information Processing and Business Equipment - UL 1950, Standard for Safety of Information Technology Equipment - CSA 22.2 #220, Information Processing and Business Equipment - CSA 22.2 #950, Safety of Information Technology Equipment - IEC 380, Safety of Electrically Energized Office Machines - IEC 950, Safety of information Technology Equipment Including Electrical Business Equipment - VDE 0805, VDE 0805 TIEL 100, and VDE 0806 The drive has been tested for compliance with FCC Class B, Part 15, Subpart J. The drive has been tested to be compatible with EMC directive 89/336/EEC. Universal Translate Mode ------------------------ Conner has established a Universal Translate Mode which enables you to configure the drive in an AT environment to any cylinder, head, and sector configuration desired. The translate configuration is limited by the maximum capacity of the drive and host system parameters. Upon initial power-up of the drive, it will default to the configuration. 1. Some BIOS are not able to handle cylinder counts greater than 4095. 2. The maximum capacity that can be handled by DOS in a single partition. 3. The native capacity of the drive in Cylinder-Head-Sector format. After the drive is ready, the host system may issue an Initialize Device Parameters command (command code 91 hex) to alter the translate configuration (number of heads and number of sectors per track). The drive will then calculate the total number of available logical cylinders based upon the values contained in the Sector Count and Drive/Head registers.
