Maximum screw penetra- tion is 3 mm with a minimum penetration of three full threads. The maximum mounting torque for these screws is 40 inch-ounces. NOTE For optimum drive performance, the system mounting method should not result in any disortion or twisting of the drive's base casting. For example, if the drive is attached (via its bottom mounting holes) to a stiff mounting surface that does not meet the GoDrive GLS flatness requirements of 0.01 inch, then head switch times may be degraded. The threaded holes in each of the four corners of the GoDrive GLS are for top cover attachment only and should never be used for any other purpose. Ventilation ----------- GoDrive GLS 85/127/170/256 S 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 GLS 85/127/170/256 S drives have a single 2 x 25 connector (on 2mm centers) for both power and data. The connector also includes four pins which are used as factory test points (these pins must be allowed to float) for the SCSI device ID (J2 pins 5 through 7), and for a drive activity LED (J2 pin 8). The recommended system mating connector is a 3M Series 150 50-pin connector or equivalent. The maximum cable length is 18 inches. The maximum cable length is 12 inches. To assure that the system cable connector is installed with the proper orientation, plug Pin 17 hole on the J1 system connector. ********************************************************************** F E A T U R E S ********************************************************************** QUANTUM GODRIVE GLS 85/127/170/256 S PRODUCT MANUAL 84-103563-02 General Description ------------------- Quantum's GoDrive GLS 85/127/170/256 S hard disk drives provide the high capacity, performance and reliability required by today's advanced 386- and 486-based notebook computers. The GoDrive GLS products offer outstanding performance, with fast time-to-data and outstanding sustained data transfer rates. These drives also offer low power consumption (0.2 watts standby). Fast spin-up times from the standby mode help conserve power and improve system response time. The GoDrive GLS hard disk drives provide extensive error correction capability, with features such as ECC on-the-fly which minimizes the impact of recoverable errors on throughput. The GoDrive GLS products feature highly reliable one,- two- and three-disk designs supported by a projected field MTBF of more than 350,000 hours. A one-year warranty is standard on GoDrive GLS drives purchased directly from Quantum or a authorized distributor or dealer. Features -------- Key features of GoDrive GLS 85/127/170/256 S hard disk drives include: - Embedded SCSI controller - Fast time to data: < 17 ms average seek time and 8.3 ms latency - Fast spin-up from shutdown: less than 2.5 seconds - Lightweight (GLS 85 4.2 ounces, GLS 256 6.1 ounces) - 96KB cache buffer - DisCache look.ahead read caching firmware for faster data retrieval - WriteCache sophisticated caching technique to streamline write commands - AccuWrite system battery backup permits accumulation of write request in the buffer - Multiple-zone recording for fast sustained data transfer rates - Low parts count for increased reliability - 112-bit Reed Solomon Error Correction Code (ECC), with 48-bit double burst correction - Defect Free Interface firmware for automatic reassignment of new defective sectors without reformatting - Automatic actuator magnetic latch and dedicated landing zone - Excellent power management to preserve battery life - > 350,000 hour projected field MTBF - Automatic diagnostic testing power-up - High shock resistance, 250g non-operating (2ms) - One-year warranty - Low profile, optimized for number of disk Seek Time --------- +-------------------------------+--------+ | |GLS SCSI| +-------------------------------+--------+ |Track-to-Track msec. typ. | 5 | +-------------------------------+--------+ |Average msec. typ. | 17 | +-------------------------------+--------+ |Full-Stroke msec. | 24 | +-------------------------------+--------+ |Latency msec. avg. | 8.3 | +-------------------------------+--------+ Quantum-Unique Drive Control Parameters, Page Code 39h ------------------------------------------------------ SSID - SOFTWARE SELECTABLE ID (Byte 3, Bit 3): When set to zero, SSID indicates the SCSI ID will be determined by the value set using the hardware ID select. When SSID is set to one, the drive SCSI ID is determined by the value set in SCSIADR (Byte 3, bits 2-0). The default is zero. SCSIADR - SCSI Address (Byte 3, Bits 2-0): When SSID (bit 3 of byte 3) is set to one, SCSIADR determines the drive's SCSI ID. When chaning the SCSI ID with the MODE SELECT command, the SCSI ID will change immediately. If at initial power on, the SSID bit is set to one - that is, if this bit's previous setting was saved on the disk - the SCSIADR bit will determine the drive's SCSI ID. The default is zero. Number of Defects ----------------- The factory limit for the number of defects per surface is 42 or one per megabyte of surface capacity. Any spare capacity not consumed at the factory is available for reallocation of field grown defects. The logical block address of a sector found defective in the field is reassigned thus maintaining the Defect Free Interface. It is reassigned to a spare sector physically closet to the defective sector. The physical address of the defective sector is added to the defect list. The defect list provides for a maximum of 292 entries.
