You must reconfigure the SCSI ID if another device is assigned SCSI ID 3 or if you are making the drive the bootable drive. The bootable drive must be Drive C. It must be assigned the ID number your SCSI adapter recognizes as the first position on the bus. Usually, this is SCSI ID 0 (refer to your SCSI host adapter documentation). If installing your new drive puts more than two drives on the bus, your SCSI adapter may require that you install a device driver or that you reconfigure its onboard BIOS. Refer to your SCSI adapter's user guide for instructions on how to install the third drive. If a device driver is required, it will be provided by the SCSI adapter manufacturer. Remote LED ---------- You can connect a remote LED to the drive using pins 9 and 10 on jumper block J8. Connect the LED ground wire (usually the black wire) to pin 9. Remote start ------------ This setting causes the drive to wait for a specific command from the host before it starts or stops the spindle motor. Parity enable. Parity is a method that is sometimes used for error detection. The drive is shipped with parity enabled. Terminators ----------- The drive is designed with single-ended drivers and receivers and must be used with other SCSI devices that use single-ended drivers and receivers. These systems require that terminators be used at both ends of the SCSI bus to ensure the integrity of the signal. The drive has built-in terminators that can be enabled or disabled as required. It is shipped with the termi- nators enabled. If you are positioning the drive at the end of the cable, you must enable the drive's internal terminators or attach an external terminator to the end of the cable. Terminators on the devices between the bus ends must be disabled or removed. - To enable the drive's terminators, leave the pin-pair 19 and 20 on jumper block J8 open. - To disable the terminators, place a jumper on pins 19 and 20 of jumper block J8. Terminator power ---------------- The terminators must have a 5 volt power source to be active. In general, the device that provides the terminator also provides power for its terminator. Power for the terminator may also be supplied through the SCSI cable (this is usually done for external terminators). The Seagate drive provides settings for four implementations of terminator power: - Terminator power to the drive terminator and the SCSI bus- install jumpers on pins 21 and 23 and on pins 22 and 24 of J8. This is the default. - Terminator power to the drive terminators only-install a jumper on pins 23 and 24 of J8. - Terminator power from another device to the bus and the drive's terminator disabled-install a jumper on pins 21 and 23 of J8. - Terminator power to the bus only and the drive terminator disabled-install a jumper on pins 22 and 24 of J8. ********************************************************************** I N S T A L L ********************************************************************** SEAGATE ST51080N INSTALLATION GUIDE 36325-001 8/1995 Notes on installation ===================== Installation direction ---------------------- horizontally vertically +-----------------+ +--+ +--+ | | | +-----+ +-----+ | | | | | | | | | +-+-----------------+-+ | | | | | | +---------------------+ | | | | | | | | | | | | | | | | | | +---------------------+ | +-----+ +-----+ | +-+-----------------+-+ +--+ +--+ | | | | +-----------------+ The drive will operate in all axis (6 directions). Attaching cables ---------------- Required materials: A four-conductor power-supply cable A fifty-conductor, nonshielded interface cable with a 50-pin, female connector attached for each SCSI device that is to be connected to the SCSI bus. The maximum cable length for asynchronous operation is 19.5 feet (6 meters). The maximum cable length for synchronous operation is 9.75 feet (3 meters). 1. Turn off the system power and put on a grounded wrist strap before proceeding. 2. Attach the 50-pin SCSI interface cable. Pin 1 on the drive must align with pin 1 of the other SCSI devices attached to the bus. Use the edge-stripe on the cable to denote pin 1. Pin 1 on the drive is located next to the four-pin power connector. 3. Connecting a remote LED. (Optional) Connect a remote LED to pins 9 and 10 of jumper block J8. Pin 9 is ground. 4. Attach an available power cable to the drive. Mounting the drive ------------------ Required materials - Four 6-32 UNC-2A screws (not included) The drive fits in the standard 3.5-inch bay and can be mounted in any orientation. Position the drive so that the cables are not strained or crimped. Secure it with four mounting screws not more than 6 full turns (0.20 inches) into the drive frame. Caution. To prevent drive mounting-hole damage, use only the type of screws specified. ********************************************************************** F E A T U R E S ********************************************************************** SEAGATE ST51080N INSTALLATION GUIDE 36325-001 REV. A 8/1995 Configuring the drive and computer ---------------------------------- Once the drive is physically installed, the drive and computer must be configured to work with each other. This involves parti- tioning and formatting the drive and may require a special device driver or installation software depending on the operating system you are using and your SCSI adapter. Refer to your SCSI adapter's documentation for specific information on how to configure your drive. This guide describes a typical configuration for a PC using DOS and one or two SCSI drives only. System setup configuration -------------------------- Required materials: - A bootable diskette with the Format and FDISK command If you are replacing the ATA (IDE) drive or drives in your computer with SCSI, you must reset the drive-type configuration listed in System Setup to Not Installed. 1. Turn the computer on. 2. Enter the System Setup routine. (Refer to your computer's user guide. System Setup may be called Setup, BIOS Setup or CMOS Setup.) 3. Find the hard disc configuration in the System Setup screen. 4. Change the drive-type status to Not Installed. 5. Save the changes and exit System Setup. Low-level formatting -------------------- Your drive was low-level formatted at the factory to 512 bytes per sector. You do not need to low-level format it again. If you choose to low-level format the drive, use the format routine supplied with your SCSI adapter. Refer to the SCSI adapter's documentation for instructions on how to low-level format the drive. Partitioning ------------ You must partition the drive into one or more logical drives before you can use it. Caution. Partitioning or formatting a drive at any level erases all data on it. Make a backup copy of your existing files on another drive before you repartition or reformat. Seagate assumes no liability if you erase your data. To partition the drive: 1. Insert a bootable diskette into Drive A. Turn the computer on. 2. After the computer has completed booting, remove the boot diskette from Drive A. Insert a diskette that has the FDISK utility into Drive A and type fdisk. Press ENTER. Note. If you have two or more drives in your system, the menu displays five options. Option five allows you to select the drive you want to partition. Make sure you select the correct drive. 3. Select create DOS partition or logical DOS drive. Press ENTER. 4. Select create primary DOS partition. Use the maximum available size for your primary partition and make the partition active for Drive C. This puts the entire drive on one partition and allows you to load the DOS boot information on the drive. Press ENTER for each subsequent selection. After all of the appropriate selections are made, the computer restarts itself. You must place a bootable diskette into Drive A. High-level formatting --------------------- High-level formatting verifies the information written by the low-level format and builds the file allocation table (FAT) used by DOS to access files on the drive. If you put more than one partition on the drive, you must high-level format each partition. Refer to your DOS reference guide for instructions. Use the DOS FORMAT utility to high-level format the drive as follows: 1. Type the following command at the DOS prompt: format drive: /v /s drive: designates the drive you are formatting. If you are formatting the boot drive or if your system contains only one drive, type c:. To format a second drive, type d:. / v tells the computer to create a volume label for the partition after it is formatted. Labeling can prevent someone from accidentally deleting the partition and losing your data. / s tells the computer to copy the necessary system files to the drive to make it bootable. 2. When the computer prompts you for a volume label, you can assign a name to the drive volume of up to eleven characters or leave it blank. Press ENTER. NonDOS operating systems ------------------------ If you are installing the drive in a system that is using an operating system other than DOS, you may need a device driver or installation software. The device driver is provided by your SCSI adapter manufacturer and is operating-system specific. It is provided on a diskette that comes with the adapter. Refer to the SCSI adapter's documentation for instructions on how to install the device driver. If you do not have a device driver for the operating system you want to install, contact the SCSI adapter manufac-turer. Installation software may be required to install the drive in some systems. There are many reputable third-party installation soft-ware packages available. Consult your dealer to determine the best package for your needs. Some operating systems require that you low-level format the drive. A low-level format routine is usually supplied on the SCSI adapter. Refer to your SCSI adapter's documentation for instructions on using the low-level format routine. Network installation -------------------- If you are installing the drive in a network environment, you may need to configure your SCSI host adapter for network operation. Refer to your SCSI adapter's user guide for assistance preparing the SCSI adapter and installing the drive. If you have trouble installing the drive with the network software, try installing it with DOS to ensure that the drive is working correctly. ********************************************************************** G E N E R A L ********************************************************************** SEAGATE ST51080N INSTALLATION GUIDE 36325-001 REV. A 8/1995 Basic troubleshooting --------------------- Warning. Always turn off the system before changing jumpers or unplugging cables and cards. If your drive does not respond or function properly when you turn the power on following the hardware installation, perform these basic checks: - Check all cards. Make sure all cards are seated securely in their slots on the motherboard. - Check all cables. Make sure all cables are securely connected. A damaged ribbon cable or connector strain relief can cause the SCSI bus to fail. Verify that the pins 1 of each device on the cable are aligned. Use the edge-stripe on the cable to denote pin 1. Caution. Improperly aligning or reverse-plugging pin 1 of one device with the other devices on the cable can damage that device or other devices. - Check the SCSI ID. Make sure the drive's SCSI ID does not conflict with that of another device. - Check the terminator configuration. If the drive is at the end of the bus and external termination is not used, the drive's terminator must be enabled. Disable or remove termination on all devices between the drive and the device at the other end of the bus. If the drive is not the last device on the bus or if external termination is used, be sure to remove the jumper that enables the drive's termination. Make sure that the drive is running. Listen carefully for the drive motor spinning. Also, the drive-activity LED flashes when the power is turned on. If the LED stays on after power-on, make sure the interface cable is properly connected and that no other device on the bus is using the same SCSI ID. - Verify your host adapter configuration. Make sure the address configurations your host adapter is using do not conflict with the addresses other devices in your system use. Refer to your host adapter's user guide for assistance. Many host adapters have a diagnostic utility that can help you determine whether such conflicts exist. Verify that the drive works when your host adapter is set with the factory-default configuration. Refer to your host adapter's user guide for assistance determining the factory-default settings. - Check the CMOS drive type. If you have an AT system, the CMOS drive-type parameter values must be set to zero or Not Installed in AT systems. - Check the power supply specifications. The output of your power supply may not meet the requirements of the new devices you are installing. If you are not sure whether your power supply meets your needs, consult your dealer. - Check for viruses. Before you load new software, scan the diskette for viruses. - Isolate the drive. If there is more than one drive in your system, configure and install the drive for single drive opera- tion. If you are installing the drive in a network, verify that the drive works with DOS. Advanced troubleshooting ------------------------ If you have performed the preceding basic checks but the problem has not been solved, follow these guidelines for analyzing specific cases: The system does not recognize the presence of the drive or system error message, "No Drives Found," appears. - Check all cables. Make sure they are properly connected and that the pins 1 are aligned. Make sure the cable is not crimped or damaged. - Check all cards for proper seating. - Check your host adapter's BIOS memory address setting. Make sure that it does not conflict with another device that sets a BIOS memory address. - Check the drive type in AT systems. The drive type must be set to Not Installed or all of the drive-type parameters set to zero. - Check the Drive C partition with the FDISK utility. The partition must be active. - Check the bus termination. The bus must be terminated at both ends. Disable or remove all terminators between the termination at the ends of the bus. - Check the terminator power source jumper settings. - Check the power-supply specifications. - Reboot and make sure the drive comes up to rotating speed. (It may be difficult to hear the discs spin.) If the drive's disc does not spin, check all drive cables. - If the drive is at least the third drive in your system, you may need to configure the BIOS for three or more drives or install a device driver. Refer to your host adapter's user guide for assistance. Contact the host adapter manufacturer for the device driver if one is required. System error message, "Drive not Ready," appears. - Check all cables. For each ribbon cable, verify that pin 1 of the cable is aligned with pin 1 of the connector. Pin 1 is usually denoted by a stripe on the side of the ribbon cable. - Check the power supply specifications. - Turn off the system and wait 20 seconds. Turn it back on and make sure the drive spins up. If the drive does not spin up, check the drive power cable. The screen stays blank when you power up the system. - Make sure the monitor is plugged in and turned on. - Check all cards. Make sure the video card is seated in its slot and secured with mounting screws. - Check all cables. Make sure the video card cables are securely attached. - Turn off the computer and remove all cards except the video card. Boot the computer. Power down the computer and add another card. Reboot. Repeat these steps until a failure oc-curs. The system hangs in FDISK or fails to create or save the partition record. - Check all cables. DOS diskette. - If you have DOS Version 4.0 or earlier, make the drive partitions smaller. - Check for media defects at the beginning of the drive. Use a third-party surface scan utility. The FDISK error message, "No Fixed Disk Present," appears. - Check all cables. - Check the power supply specifications. - Make sure the drive spins up when you turn on the system. - In AT systems, check the drive type. The drive type must be set to Not Installed or the drive-type values set to zero. - Check for I/O address conflicts. During the DOS high-level format, the drive keeps retrying hard errors and reporting the following message. "Attempting to recover allocation units. . ." - This is normal with DOS Version 4.0 or later. DOS messages, "Disk Boot Failure," "Non-System Disk," or "No ROM Basic - SYSTEM HALTED," appear. - Remove the diskette from the diskette drive. - Check all cables. - Use the same version of DOS throughout your system. - Reinstall the DOS system files using the DOS SYS utility. - Make sure the primary partition is active in FDISK. - Check for viruses.
