Installation Guide for MiniScribe Models 3650 & 3675 This guide will allow you to install a MiniScribe hard disk drive into your IBM penI AT orcrone~system: Please read the entire installation guide before attempting to install your hard disk drive. Installation 1. Set the drive on a padded surface (anti-static if available) with the printed circuit board facing up. (If available. a properly grounded write strap should be worn during this installation.
If the 34 pin ribbon cable has a twist (see fig. 1) at the end connector. attach the first drive (C) to the end (twisted) connector. and the second drive (D) to the inner connector. Configure both drives (C & 0) for drive select 1 (DS 1). For a single drive installation. attach the drive to the end (twisted) connector and configure as drive select 1 (OS 1). -~4. When installing a single drive. the resistor termination pack (RPI) must remain installed. When installing two drives.
MINISCRIBE CORPORATION INSTALLATION GUIDE FOR MINISCRIBE MODEL 3053 This gUide will allow you to install a MiniScribe hard disk drive into your IBM PC XI' / AT or clone system. 1. Set the drive on a padded surface (anti-static if available). with the printed circuit board facing up. 2. If your system requires the use of mounting rails to secure the drives. attach them in the orientation that best fits your system. 3.
When attaching the first drive (C) to the twisted connection of the 34 pin ribbon cable (see figure 1). and the second drive (0) to the nontwisted connection of the 34 pin ribbon cable. configure both drives as drive select 2. when--attachTrig the firsldfive (C) to the non-twisted-connectlon of the34 pin ribbon cable and the second drive (0) to the twisted connection of the 34 pin ribbon (See Figure 1). configure both drives as drive select 1.
PARKING HEADS ON MODELS 3650 AND 3675 In the month of July, 1988 MiniScribe's Recon facility reported that 76°A> of the Model 3650 and 3675 drives arrived with the heads NOT ---PARKED- at the "land1ng-zon~' ,which-on these models is Cylinder- 852. As you know, drives "not landed" could seriously damage the heads and disks of the drives when they are in transit. resulting in high scrap cost. and possibly voiding the warranty of the drive.

HANDLING AND PACKING CAUTION /WARNING The MiniScribe drive is a precision product. During handling, the product must not be dropped. jarred or bumped. Otherwise. damage to the heads and disks may occur. When the drive is removed from the MiniScribe shipping container and not immediately secured within a chassis through its shock mounts. it must be stored on a soft padded conductive (antistatic) surface. UNPACKING AND INSPECTION SINGLE PACK A Retain the packing materials for reuse.

COlWPATIBILITY Interfaces ST506/ST412 The ST506/ST412 interface has been an industry standard since 1981. It is primarily intended for low-cost. low-capacity applications. This interface standard places most of the drive subsystem's logic on the controller. The drive in this installation is primarily a recording device. The compatibility from drive to controller is primarily centered around one question.
SCSI The SCSI (Small Computer Systems Interface) differs from the previous interfaces in that it is not dedicated only to hard disk interfacing. It will allow printers. floppy drives and other devices to share a common interface. The SCSI interface allows the computer to communicate with up to eight separate devices. With SCSI most of the drive control is designed into the drive. The SCSI bus transfers bytes of infonnation in parallel rather than in serial form like the ST506/ST412 and ESDI interfaces.
When used with controllers with BIOS low-level formatters it is generally necessary to initialize the drive with the BIOS formatter. Then the installation software is used to partition and prepare the drive. The three steps necessary to prepare a drive for use are as follows: I. lhitia.IiZe(lbw-level-formatl the drive (with utility disk; controllerBIOS routine. or install/partitioning software). 2. Partition the drive (with DOS Fdisk command or partitioning software). 3.
RLL has recently become popular and is based on a 7.5 megabit per second transfer rate. Because of the higher transfer rate. more data can be put onto a track: 26 sectors of 512 bytes or 13312 bytes per track. 7.5 mega bits per second is 50% faster than 5.0 megabits per second. A drive running MFM might yield 20 megabytes and 30 if it can run RLL. -RLL is similar enough to MFM so that no major redesign of the drive was required. Differences however do exist.
~PRECOMPENSAnON If you were to look at the drive's data Signals they would appear as electronic pulses. The frequencies used to generate .these pulses are stepped up and down at very specif1c intervals. This is necessary for the controller to be able to track the data as it is being read. . As the drive records toward the inner portions of the disk these precisely timed .
DISK MANAGER BY ONTRACK COl\fPUTER SYSTEMS PC-XT 1YPE CONSIDERATIONS Approach 1: If your controller card has a switch or jumper setting which correctly matches all parameters necessary for correct operation of your particular disk drive. you should set those switches/jumpers accordingly. The drive should then be treated as a "STANDARD" drive when using DISK MANAGER.
PC-XT TYPE SELECTION CRITERIA The chosen TYPE must be smaller or equal to the actual disk drive you are installing in BOTH the head-count and cylinder-count dimensions. Further. it is deSirable to match AS CLOSELY AS POSSIBLE the head-count between the drive-type and the drive you are installing. For further information on the consequences of this parameter. read the section below on CAPACITI REDUCTION.
CAPACOY REDUCTION The DOS partition (necessary ONLY to boot) on a NONSTANDARD disk can use ONLY the part of the disk depicted by the BIOS ROM for the particular drive-type you have chosen (With--switche-s-~-Jumpers;--CMOS,--etc.).---Therefore, if you have a drive which DOES NOT have a drive-type entry with the same number of heads, the DOS partition will effectively WASTE DISK SPACE. If the head-count mismatch is severe.
