All drive performance characterization however, has been done with the drive in horizontal (disc level) and vertical (drive on its side) orientations, and these are the two preferred mounting orientations. The drive is designed, manufactured, and tested with a "Plug-in and Play" installation philosophy. Basically, this philosophy minimizes the requirements for highly trained personnel to integrate the drive into an OEM's system, wether in a factory or field environment. - If one drive is on the AT (IDE) bus, insure that the AT (IDE) bus ID of the drive is set for drive 0. - If two devices are on the bus insure that the drive 0/ drive 1 ID Jumper of each drive is correct for its position on the bus (select a drive 0 and a drive 1). - If the drive is the only device on the bus it should be attached to end of the AT (IDE) bus cable (18 inch max length). - Set all appropriate option jumpers for desired operation prior to power on. If jumpers are changed after power has been applied the drive must be power cycled for the new settings to be affect. - In all cases where additional drives are added on the AT (IDE) bus it will be necessary to logically install the new drive onto the system. Mounting Holes -------------- Four 6-32 UNC-2A screws are required for installation. Maximum mounting screw length into chassis is 0.125 inches (3.17 mm). Cooling ------- The cabinet cooling must be designed by the customer so that the ambient temperature immediately surrounding the drive will not exceed temperature conditions. Specific consideration should be given to make sure adequate air circulation is present around the components on the PWA. Service Tools ------------- No special tools are required for site installation or recommended for site maintenance. The depot repair philosophy of the drive precludes the necessity for special tools. Should repair of any part of the drive be desired, drive should be sent through purchase source to the factory repair depot. There are no spare parts for the drive avaiable. Call 1-800-468-3472 if purchase source cannot arrange for return of the drive. Air Cleanliness --------------- The driv is designed to operate in a typical office environment with minimal environment control. Interface Cabling Options ------------------------- The drive is capable of operating on the AT (IDE) bus in a daisy chained configuration with a second drive/controller that operates in accordance with these specification. One drive is designated as master (drive 0) and the other as the slave (drive 1). +-----------------------------------------+ | HOST | | I/O | +---------+-------------------------------+ | | +----------------+ +---------+--+ +----------+--+ | AT (IDE) | | AT (IDE) | | Drive 0 | | Drive 1 | +------------+ +-------------+ DC Cable and Connector ---------------------- The drive receives DC power through a 4 pin connector mounted on the main circuit board. Recommended part numbers for the mating connector are included below, but equivalent parts may be used. Type of cable: 18 AWG Connector: AMP 1-480424-0 Contacts: AMP 60619-4 (Loose Piece); AMP 61117-4 (Strip) I/O Cable and Connector ----------------------- The I/O connector is a 40 pin connector. A key is provided by the re- moval of Pin 20. The corresponding pin on the cable connector should be plugged. Seagate recommends keying this connector to prevent the possibility of installing it upside down. Maximum I/O cable length is 18 inches (.45 metres). Recommended part numbers for the mating connector are included below, but equivalent parts may be used. Connector: 40 pin, 3M-3417-7000 (Strain relief 3448-2040) Cable: Flat Cable (Stranded AWG 28) 3M-3365-40 Flat Cable (Stranded AWG 28) 3M-3517-40 (Shielded Cable) Grounding --------- Signal ground (PWA) and HDA ground are connected together in the drive and cannot be separated by the user. The chassis ground is not connected to the HDA and PWA ground. A chassis grounding quick disconnect Tab is provided at the rear of the drive above the DC power connector. Mating connector to connect a system chassis ground to the grounding tab is AMPP/N 62137-2. If it is desired for the system chassis ground to be connected to the HDA/PWA ground, the systems integrator or user must provide a flexible ground strap be- tween HDA and chassis ground point. Such a strap must not interfere with the ability of the HDA to meet shock and vibration specifications. ********************************************************************** F E A T U R E S ********************************************************************** SEAGATE ST1480A FAMILY PRODUCT MANUAL 77738463-B General Description ------------------- The ST1480A Family drives are members of a family of low cost, high performance, highly reliable, random access storage devices designed to meet the needs of the OEM, AT (IDE) compatible, marketplace. Standards --------- The ST1480A Family has been developed as system peripherals to the highest standards of design and construction. The ST1480A Family drives depends upon their host equipment to provide adequate power and environment in order to achieve optimum performance and compliance with applicable industry and governmental regualations. Special attention must be given in the areas of safety, power distribution, shielding, audible noise control, and temperature regulation. The ST1480A Family complies with Seagate standards. Each Member of the ST1480A Family UL Recognized component per UL 478 or UL1950 and a CSA Certified component per CSA C22.2 No. 220-M1986 or CAN/CSA-C22.2 No. 950-M89.It also meets the requirements of DIN VDE 0805/05.90, and EN 60950:1988 (IEC 950). The drive as delivered, is designed for system integration before use. It is supplied as a component or subassembly as defined in the FCC Rules and Regulations, Part 15, Subpart J governing EMI of computing devices and the Radio Interference Regulations of the Canadian Department of Communications. The drive is, therefore, not directly subject to the FCC rules and regulations or the Radio Inter- ference Regulations of the Canadian Department of Communications. The head, disc and actuator chamber (HDA) is environmentally sealed at the factory. Air is recirculated within the HDA and passes through a nonreplaceable filter to ensure the maintenance of a contamination free disc/actuator environment. The ST1480A Family uses a dedicated landing zone at the innermost radius of the media thus eliminating the possibility of destroying or degrading data by landing in the data zone. Head parking is done automatically by the drive. The Host need not send a command that sends the heads to the parking zone. The ST1480A Family drives incorporate an automatic shipping look which prevents potential damage to the heads and discs caused by movements during shipping and handling. The shipping lock is automatically disengaged when power is applied to the drive. The ST1480A Family drives decode Track 0 location from the dedicated servo surface thereby eliminating mechanical transducer adjustments and related reliability concerns. The ST1480A Family drives use a high performance actuator assembly consisting of a low inertia, balanced, patented, straight arm design which provides excellent performance with minimum power dissipation. Media Description ----------------- The media used on the drive has a diameter of approximately 3.5 inches (89 mm). The aluminum substrate is coated with a thin film magnetic material, overcoated with a proprietary protective layer for improved durability and environmental protection. Each data surface has a total of 1474 tracks and is capable of storing 54 Mbytes of unformatted data. Media defects are characterized as correctable or uncorrectable de- pending on the type and magnitude of the media flaw. The drive media certification is performed using the following standards: An error burst of 11 bits or less is a correctable error. An error burst greater than 11 bits in length is an un- correctable error. In each ot the above cases reallocation is performed during factory media certification testing. In other words, all known correctable or uncorrectable defects are reallocated at the factory. At the time of shipment from the point of manufacture, the drive recording surfaces will meet the following requirements. 1. 1475 total physical tracks per surface. 2. Tracks 0 to be error free on each data surface. 3. 50 defects per surface maximum. 4. Accumulative defects not to exceed one per megabyte, based on total available unformatted drive capacity. Defect and Error Management --------------------------- The drive, as delivered, complies with this specification. The read error rate and specified storage capacity are not dependent upon use of defect management routines by the host. Defect and error management in the AT system involves the drive internal defect/error management and AT system error considerations (error in communications between host and the drive). Tools for use in designing a defect/error management plan are briefly outlined in this section, with references to other sections where further details are given. Drive Internal Defect/Errors ---------------------------- Identified defects are recorded on the drive defects list tracks (referred to as the primary or ETF defect list). These known defects are assigned new locations during the initial drive format operation at the factory. The drive internal retries and data correction by ECC should be enabled to recover data from additional flaws if they occur. If data correction by ECC is required to recover data, the host should immediately re-assign or mark the sector "bad block" by use of the Format Track command. If the drive automatic retries and data correction by ECC are disabled, defects are usally unrecoverable and need to be re-assigned or marked "bad block" as they are discovered. Logical Capacity ----------------- The drive has an embedded controller that has the capability to translate the drive's actual, physical heads, cylinders and sectors values to logical, apparent values when communicating with a host controller. Thus a host system not having a disc drive table entry that fits the drive physical configuration can install the drive as a drive having a heads, cylinders and sectors configuration matching some drive that is listed in the Host's BIOS drive table. The host sends the Initialize Drive Parameters command to the embedded controller in the drive and it translates the drive's physical heads and sectors to whatever they need to appear to be to install on the host system as they selected type. The capacity achieved in the translate mode depends on the logical configuration to which the drive "translates". The Logical configuration must equate to less than or equal to the drives maximum specified capacity. Recommended Logical values of parameters are as follows: ST1480A 895 cylinders 15 heads 62 sector/track ST1400A 1018 cylinders 12 heads 53 sector/track ST1401A 726 cylinders 15 heads 61 sector/track Formatting ---------- It is not necessary to low level format this drive. The drive is shipped from the factory low level formatted in 512 byte physical sectors. The drive translates its physical format structure to simulate a Logical format as required by host.

Average seek time is determined by dividing the sum of the time for all possible seek movements by the total number of seek movements. Drive level seek times do not include controller overhead, the time required by the drive controller to process the command. Spindle Speed and Latency ------------------------- The spindle speed is 4412 0.5% r/min. The speed tolerance includes motor performance and motor control circuit tolerances. The average latency time is 6.80 milliseconds, based on a nominal disc speed of 4412 r/min. Host/Drive Interface data transfer rate --------------------------------------- Maximum instantaneous: 8.0 Mbytes/s Maximum average: 5.5 Mbytes/s Power Sequencing ---------------- Power sequencing is not required for the drive. The drive protects against inadvertent writing during power up and down. Temperature ----------- The drive will meet all specifications over a 41*F to 122*F (5*C to 50*C) ambient temperature range with a maximum gradient of 36*F (20*C) per hour. The enclosure for the drive should be designed such that the temperatures at the locations are not exceeded. Air flow may be needed to achieve these temperature values. Operation at case temperatures above these values may adversely affect the drives ability to meet specification. Heat/Power Dissipation ---------------------- Typical power dissipation is 12 watts (41 BTUs per hour) of DC power average at nominal voltages. Typical power dissipation under idle operating conditions is 9.5 watts (32.4 BTU's per hour). Reliability ----------- The following reliability specifications assume correct host/drive operational interface has been implemented, including all interface timings, power supply voltages, environmental conditions, and appropriate data handling circuit to the host system.
