However, hard disk drives can be damaged fairly easily. Observe the following precautions so as not to void your warranty: Do not drop the drive or handle it carelessly. Keep all liquids and moisture away from the hard drive. Protect the drive from extreme temperatures. Follow configuration and installation instructions carefully. Carefully follow the static electricity precautions below. Read through all the instructions before beginning the installation process. Before opening your system case, read and follow these preventions and precautions to prevent damage from static electricity. Caution! Preventing Static Electricity Damage The components inside your system are extremely sensitive to static electricity, also known as electrostatic discharge (ESD). Static electricity can cause irreparable damage to your system; however, if you follow these preventions and precautions, you should prevent such damage. Static Electricity Preventions WEAR A GROUNDING WRIST STRAP (available at most electronic stores). Turn off the system power. Touch the back of the power supply fan, located on the back of the case. UNPLUG ALL CORDS FROM WALL OUTLET. Remove the system case cover. Static Electricity Precautions Avoid static-causing surfaces such as plastic and styrofoam in your work area. Remove parts from their antistatic bags only when you are ready to use it. Do not lay parts on the outside of antistatic bags since only the inside provides antistatic protection. Always hold cards by their edges and their metal mounting bracket. Avoid touching components on the cards and the edge connectors that connect to expansion slots. Never slide cards or other parts over any surface.   Configuring the Drive This hard disk drive is SCSI Configured AutoMatically (SCAM) protocol compliant. SCAM automatically sets your SCSI devices’ SCSI IDs. If this drive shipped as part of a system, it is linked with a SCAM-compliant SCSI host adapter. Your SCSI adapter documentation contains configuration instructions for the SCAM protocol. This manual contains information on configuring this drive in a non-SCAM compliant environment.   About the SCSI chain All the devices on the SCSI Ultra Wide 68-pin ribbon cable connect to form a chain. This chain contains a SCSI host adapter and up to fifteen other Ultra Wide SCSI devices, such as your hard disk drive. In other words, the ultra wide SCSI chain may have up to sixteen links. To configure the SCSI devices properly on the SCSI chain, you must designate the ends of the chain (termination) and determine the order of the links (IDs) between the ends of the SCSI chain for your computer, so it addresses the SCSI devices properly.   Termination Each device on the SCSI cable is either an end of the chain or a link in the middle. This SCSI drive has a terminator jumper which can be set to on or off, depending whether the device is an end or a middle link in the chain. Generally, your system’s SCSI host adapter is at one end of the chain, and a terminated device is at the other. All other devices are middle links. The SCSI host adapter can be set so you can boot from any device on the SCSI BUS.   SCSI IDs (Non-SCAM) In addition to recognizing the ends of the SCSI chain, your system needs to designate the order of the links. For this reason, each device on the SCSI chain requires a unique device ID. This ID can be any whole number between 0 and 15 other than 7, which is the factory preset for the host adapter. The ID number, or address, can be set on most SCSI devices by adjusting jumpers on pins. (See the section titled, "To configure the Hard Disk Drive" for instructions on how to set the ID number for your hard disk drive.) Note: This drive supports the SCSI Configured AutoMatically (SCAM) protocol Consult your SCSI host adapter documentation to ensure SCAM compatibility and for SCSI ID configuration instructions. Follow the SCSI ID and termination instructions in host adapter documentation if you configure your Seagate SCSI Ultra Wide hard disk drive using the SCAM protocol. Figure 1.

Double-check these settings on your drive with the terminator and SCSI ID settings (See Figures 2 through 4 depending on your drive) portrayed for an active terminator and SCSI ID 0. Proceed to the section titled, "Installing the hard disk drive." Note: If this drive came as part of your original system, it is configured automatically using the SCAM protocol. SCAM automatically sets the SCSI IDs for all the SCAM-compliant SCSI devices. Follow the instructions for setting SCSI IDs if you disable the host adapter’s SCAM protocol or if you’re introducing this drive into a system that does not operate with the SCAM protocol. If you’re installing the hard disk drive into a non-SCAM system as a drive from which you don’t boot your system, follow the instructions below to change its terminator and its SCSI ID. Determine which ID your drive uses. If this is the second drive, use 1; if this is the third drive, use 2, etc. Locate jumper J1-Auxiliary or jumper J6 (see Figures 7 through 12 depending on your drive). Use only one jumper block to set SCSI IDs. (We recommend using Jumper J1-Auxiliary because it is more easily accessible once the drive is installed.) Set the drive’s SCSI ID by positioning a shunt(s) over the appropriate pin pair(s) on jumper J1-Auxiliary or J6 (see Figure 2). Figure 5. Typical Jumper Pin Pair Shunt Pin pair   The terminator is controlled by jumper J2; locate J2 on the bottom of the drive (see Figure 3 or 4 depending on your drive). Note: If one or both pins in a pin pair are not covered by a plastic cover or shunt, the pin pair is open. If both pins in a pin pair are covered by a shunt, the pin pair is closed. Since your drive was shipped with the terminator activated as shown in Figure 3 or 4 (depending on your drive), you just deactivate by removing the shunt from the pin pair marked TE on jumper J2 (see Figure 3 or 4 depending on your drive). Store the shunt in a safe place should you need to terminate your drive later. Proceed to the section titled, "Installing the hard disk drive."   Installing the Drive Before installing the hard disk drive, insure that the SCSI host adapter and any other SCSI devices are configured according to their places. Please read through all the instructions before beginning.   To install the hard disk drive: Power down the system. Remove your system’s cover (refer to the documentation that shipped with your computer). Please read all static electricity preventions and precautions in the "Warnings and precautions" section. If your system requires rails, install them on the hard drive. Slide the drive into the empty drive bay. If your system uses rails, fasten the tabs to the front of the chassis. If your system does not use rails, fasten the hard drive into place in the bay with two screws on each side of the drive.   About connecting cables The hard disk drive connects to your system through a 68-pin SCSI ribbon cable and a power supply cable.   The 68-pin SCSI ribbon cable The Seagate Ultra Wide SCSI drive uses a 68-pin connector ribbon cable to carry data between the drive and the host adapter. The connector is keyed so that it fits only one way. The host adapter connects to one end of the SCSI ribbon cable, and the boot drive is connected at the other end. Other SCSI drives and devices connect to the middle connectors.

Connect the other end of the ribbon cable to the primary drive, making sure its red stripe faces the drive’s power supply connector. Connect the rest of the SCSI devices to the appropriate connectors on the ribbon cable, making sure each connection is oriented properly (red stripe faces the device’s power supply connector). Double-check to ensure that each connection is secure.   The power supply cable Each device on the SCSI cable requires a connection to the system’s power supply. A power supply cable is a set of four wires that leads from the system’s power supply to various system devices. At the end of this wire is a 4-pin connector, keyed so that it can be inserted only one way.   To connect the power supply cable: Select an unused 4-pin, multicolored power supply cable coming from your system’s power supply (Any of these cables may be used). The cable attaches to the 4-pin connector on the back of the hard disk drive (See Figure 9 or 12 depending on your drive). Carefully insert the cable into the connector, being sure not to bend or dislodge any of the pins. Make sure the connection is secure. Replace your system cover. Read the next section, "About Partitioning and Formatting a Drive."   About Partitioning and Formatting a Drive In order for an operating system (such as MS-DOS or Windows) to store files on a hard drive, the disk must be partitioned and formatted. Note: Both the partitioning and formatting procedures destroy ALL files on the hard drive. Partitioning a disk designates which area(s) of the disk are used for the operating system files. Windows uses the MS-DOS partition file fdisk.exe. FDISK allows you to set up a primary DOS partition, extended DOS partitions, and logical drives within the extended DOS partitions. A primary DOS partition contains the essential files to boot your system from the hard drive (system files). To boot to Windows from your hard drive, you must have a primary DOS partition and it must be set to active. An Extended DOS partition is a portion of a hard drive where non-system files can be stored. Unlike a primary DOS partition, you cannot boot your system from an extended DOS partition, and your system does not require an extended partition to function. A Logical Drive is an area of an Extended DOS partition that you can set up to group directories and files; it does not increase disk storage capacity. You must set up an extended DOS partition before you can establish a logical drive. You can create up to 23 logical drives in an extended DOS partition. Formatting a hard drive prepares the section to receive files. Windows uses the MS-DOS file, FORMAT.COM, to format disks.   Partitioning and Formatting the Drive The MS-DOS File Allocation Table 16 (FAT 16) allows your system to address only about 2.1GB of hard drive space per partition. Your system, though it uses LBA Translation Mode, has this limitation. Because of this limitation and the size of this drive, your system — if it has LBA — configures two drives on the 4GB drive, or four drives on the 9GB drive during the partitioning and formatting process. Note: If you received the 4GB drive with your system, we partitioned it into two drives (C:\> and D:\>) before we shipped it. If your system came with a CD-ROM drive, the CD-ROM is the E:\> drive. If you received the 9GB drive with your system, we partitioned it into four drives (C:\>, D:\>, E:\> and F:\>) before we shipped it. If your system came with a CD-ROM drive, the CD-ROM is the G:\> drive. After your system recognizes the drive, it is ready to be partitioned and formatted. Even if you plan to run just one operating system (MS-DOS, for example), you must still create a partition. Your operating system backup software includes the FDISK and FORMAT files. It shipped with your system in one of three different ways as described in the following sections. First, figure out which of the following three possibilities is consistent with the media that shipped with your system and make sure you have the necessary diskettes and/or CDs readily available.   The system diskette and the Windows 95 CD If your computer shipped with Windows 95 installed, you can use the system diskette to partition and format your hard drive and the Windows 95 CD to install the Windows 95 operating system if necessary.   The system diskette and the System CD (starting with version 4.3) or the Operating System CD If your computer shipped with MS-DOS on the System CD or the Operating System CD, use the system diskette to partition and format your hard drive and either the System CD or the Operating System CD to install the MS-DOS and Windows operating system if necessary.   The MS-DOS Setup diskettes If your system shipped with the MS-DOS Setup diskettes, use the Setup diskettes to partition and format your hard drive and to install the MS-DOS operating system if necessary.   Partitioning the drive Two sets of steps are included in this section. Use the first set to partition the hard drive as the primary drive; use the second set to partition the hard drive as a secondary drive. All files are erased during this process.   To partition as the primary (boot) drive: Use these instructions if you have configured and installed your drive as the drive from which you boot your system. Place the system diskette or the MS-DOS Setup diskette in the 3.5-inch floppy drive. Start up the computer. An Important Note screen may appear. If so, press <Enter> to clear the screen and disregard the message at this point. The System Diskette Main Menu screen appears. Using the arrow keys, highlight option 4 (Exit). Press <Enter>. A:\> prompt appears on the screen. Type: fdisk and press <Enter>. The FDISK screen appears. Choose option 1 (Create DOS Partition or Logical DOS Partition) from the FDISK Options menu and press <Enter>. A message appears inquiring as to whether you want the primary DOS partition to be the maximum size available or a smaller size. Choose the appropriate option and press <Enter>. Note: Remember that if you choose to make the primary DOS partition less than the maximum size, you must create an extended DOS partition to make full use of the drive. Set the primary DOS partition to Active. When you are finished partitioning the drive, exit FDISK. Continue with the section titled "Formatting the drive."   To partition as a secondary drive: Use these instructions if you have configured and installed the drive as a non-bootable drive used for file storage. The drive letters used in these steps assume that you are installing a second drive for file storage; if you are installing a third or fourth drive, substitute the appropriate drive letters as necessary. With the system diskette or the MS-DOS Setup diskette in the 3.5-inch floppy drive, power up the system. The system powers up to an A:\> prompt. At the A:\> prompt, type: fdisk and press <Enter>. The following screen appears. Type: 5 and press <Enter>.   Your computer recognizes the new hard drive as Disk 2, Drive D (your numbers and letters may differ depending on the number of hard drives already present in your system). Type: 2 (or the appropriate number of the hard drive you have just installed) and press <Enter>.   The "FDISK Options" screen reappears. Type: 1 and press <Enter>.   A screen labeled "Create Extended DOS Partition or Logical DOS Drive" appears. Type: 2 and press <Enter>.   A screen labeled "Create Extended DOS Partition" appears. Press <Enter> to accept the default values for each option presented. When prompted, press <Esc> to continue. The "Create DOS Partition or Logical DOS Drive" screen reappears. Type: 3 and press <Enter>.   A screen labeled "Create Logical DOS Drive(s) in the Extended DOS Partition" appears. Press <Enter> to accept the default values for each option presented. When prompted, press <Esc> to continue. When you are finished partitioning the drive, exit FDISK. Continue with the section titled "Formatting the drive."   Formatting the drive Use these steps to format the drive after using FDISK as instructed to partition the drive. Make sure your system diskette or your MS-DOS Setup diskette is still in the floppy drive and you are at the A:\> prompt. All files are erased during this process.   To format the drive: At the A:\> prompt, type: format c: (or the appropriate letter of the hard drive you have just installed) and press <Enter>.   Note: If the drive you are formatting is the boot drive (usually the C:\> drive) type: format c: /s to format the drive as a boot drive. The format program asks if you wish to proceed with the format. Press <Y> to continue. When the hard drive is formatted, the system asks you to label the hard drive. Labeling is optional; you can press <Enter> to clear this question or type a label name and press <Enter>. The hard drive is ready to accept files for storage.   Finishing the Installation You have configured and installed the drive, recognized the drive through the system’s Setup program, and partitioned and formatted the drive.   To finish the installation: Shut down the system and unplug the system’s external cables. Check to make sure the internal connections are secure and are arranged so they will not catch on the case cover. Replace the case cover. Reattach the system’s external cables. If the new hard drive is NOT your primary hard drive, power up the system and restore any files and applications you desire from your backup copies. OR If the new hard drive IS your primary hard drive, you need to reinstall your operating system. Use the operating system software that shipped with your system to reinstall the operating system; instructions are included with the operating system software for your reference. After installing the operating system, restore any files and applications you desire from your backup copies. Note: If your applications don’t run after restoring them, install them from the original program media.   Troubleshooting If a hard drive fails to operate after you install it, go back and check your work against the instructions in this manual. Here are some potential problem areas: You haven’t made a partition with FDISK yet. Make sure to create at least one partition, and that the primary DOS partition is activated. Drive formatting was not done properly. If you have more than one partition, remember to format separately each logical drive you create. You forgot to connect the drive to the power supply. The hard drive interface cable is connected incorrectly. Make sure that the dotted or colored edge of the data (ribbon) cable connects to Pin 1 at each connector. Jumpers on the system board or drive are set incorrectly. The hard drive cable is defective. Install a new cable.   Notices   All rights reserved This publication is protected by copyright and all rights are reserved.
