WINDOWS 32-BIT DISK ACCESS
The 32-bit disk access feature in Windows 3.1 does not work with drives that have capacities greater than 528 Mbytes. If you want to use this feature, install the Seagate replacement 32-bit access driver, SEG32BIT.386, located on your Seagate software diskette.
If, during installation, Windows 3.1 activates the 32-bit disk access feature in your system, a message suggesting that you disable 32-bit disk access appears the first time Windows loads into memory. Choose to disable 32-bit disk access to open Windows.
To install the Seagate 32-bit disk access replacement driver:
1Place your Seagate software diskette into Drive A.
2Open the Windows Program Manager menu and select File.
3Select Run.
4In the command line box, type a: \stsetup.exe.
5Read the license agreement that appears on the screen. If you agree to the terms, select Accept Agreement to continue.
6The next screen lists the features the SEG32BIT.386 driver supports. If your computer supports these features, they will be active in 32-bit disk access mode with SEG32BIT.386 for all drives that support them. Select Install Driver to continue.
To make the feature active, you must enable the 32-bit disk access option in the Windows control panel. Open the Control Panel. Select 386 Enhanced. Select Virtual Memory. Select Change>>. Select Use 32-Bit Disk Access (an X in the box enables the feature). Save the change.
INSTALLATIONOPTIONS
This section provides a brief discussion of the options on the options jumper block. The drive comes with a spare jumper on pins 1 and 3.
Single Drive or Master with an ATA-Compatible Slave
This is the factory-default setting.
Slave
To make the drive the slave, place a jumper on pins 7 and 8.
Master with Slave Present
This option allows you to use a non-ATA-compatible slave with your Seagate drive as the master. Place a jumper on pins 5 and 6.
Cable Select
Some computers differentiate between master and slave drives using specially designed interface cables that have the line to pin 28 (the Cable Select pin) removed or cut at one end. The connector that has pin 28 disabled is used for the slave drive. See your computer manual to determine whether your computer supports this feature. To configure the drive for cable select, place a jumper on pins 3 and 4.
ADVANCEDDISKMANAGEROPTIONS
General
Disk Manager partitions and formats your drive. It installs the Dynamic Drive Overlay (DDO) software driver to provide access to the drive’s full capacity if your computer’s BIOS is not configured to access more than 528 Mbytes. DDO bypasses the BIOS during the boot sequence and loads the drive information before DOS is loaded. Disk Manager:
•Provides an easy installation option that partitions and formats the new drive in seconds
•Provides an easy-to-use format if you want to customize your drive installation
•Installs a software driver, Dynamic Drive Overlay, that allows the computer to access the full capacity of your Seagate drive when the BIOS limits the drive capacity to 528 Mbytes
•Modifies the boot record with geometry for the new drive if the Dynamic Drive Overlay driver is required
•Copies the system files onto the new Drive C to make it bootable
•Enables read/write multiple, a feature that increases performance by allowing multiple blocks of data to be transferred in a single burst if your computer also supports this feature
•Provides full drive-capacity support for several operating systems
•Provides complete, easy-to-use online documentation
Booting with a Diskette
If Disk Manager installs DDO to access the full capacity of your drive, the information DDO uses to access the drive must load into memory before the operating system loads into memory. This occurs automatically when you boot to Drive C. To gain access to the drive when booting to Drive A:
1Boot the computer with the Drive A door open.
2When the Disk Manager banner appears, immediately press the SPACEBAR (you have about 2 seconds).
3Insert the boot diskette and press the SPACEBAR.
If you boot with a diskette regularly, you can create a Dynamic Drive Overlay boot diskette. It loads DDO into memory before loading the operating system. See the online manual for information on how to create a Dynamic Drive Overlay boot diskette.
Supported Operating Systems
Dynamic Drive Overlay provides full drive-capacity support for the following operating systems:
MS-DOS
Windows 3.x
Windows NT 3.51
Window NT 3.50 (requires DM upgrade drivers)
Windows 95
OS/2 V3.0 (Warp full pack)
OS/2 V2.0–3.0 (requires DM upgrade drivers)
If you are installing an operating system other than DOS, you must first install your drive with DDO and make sure that it is bootable before you install the other operating system. Installation instructions for other operating systems are available in the online manual. To open the online manual:
1Go to the Select an Installation Option menu.
2Select (V)iew/Print Online Manual.
3Select Operating System Installation.
4Select the operating system you want to install.
You can also open the online manual from the command line. Type dm/h and press ENTER. Press ENTER again to open the online table of contents menu.
Note. If your are installing OS/2 or Windows NT, we suggest that you print the instructions before you start the installation.
To use DDO with OS/2 and Windows NT V3.5, you must replace up to four of the original files with files supplied by Disk Manager. The replacement files are located in the OS2 and the NT subdirectories on your Seagate software diskette. The online manual tells you which files you need to replace and under what conditions to replace them. If you need assistance renaming a file, refer to your DOS reference manual. If you need to make a copy of an installation diskette, follow the instructions below—the installation diskette will not install if you use the standard copy command to copy it.
1Insert the original diskette into Drive A and access the drive.
2Type diskcopy a: a:. The computer will read the original diskette and prompt you to insert the destination diskette into Drive A.
3Insert a blank diskette into Drive A and press any key.
Erase the files you need to replace on the new diskette, and copy the replacement files using the standard copy command. (If only one diskette drive is available for copying, first copy the required files to the hard drive from the appropriate subdirectory, then copy the files to your new diskette.)
RemovingtheDynamicDriveOverlay
If Disk Manager installs your drive with DDO, you can, in many cases, remove DDO without losing your data. However, you will lose access to the full capacity of your drive unless you use another method that supports more than 528 Mbytes (see “Accessing More Than 528 Mbytes” on the front side). Three steps are required to remove DDO safely: 1) migrating the data, 2) configuring Setup with the drives’s translation and
3)uninstalling DDO. Follow the instructions below to remove DDO safely.
!Caution. Before you attempt to remove DDO, back up your data files. You may need to use the backup
files to restore your disc if your data is lost.
If the migration encounters a media defect or is interrupted by a power loss or hardware failure, the migration will fail and your data will be lost. Run CHKDSK, SCANDISK or a third-party equivalent to detect and repair any media defects before you attempt the migration.
1Boot the computer to Drive C.
2Put your Seagate software diskette into Drive A and access the A prompt.
3Type dm and go to the Select Installation Options menu.
4Select (M)aintenance Menu.
5Select (M)igrate Dynamic Drive. This program shifts the data to where the standard format can find it. The migration may take up to an hour to complete, depending on the size of your drive.
6When the Migration is complete, exit Disk Manager.
7Remove the diskette, reboot the computer and enter Setup.
8Configure the hard drive with the parameters shown for your drive in the translation geometry table in Section 3, “Configuring Setup,” on the front side of this guide. Save your changes and exit Setup.
9When the boot is complete, insert the diskette and access the drive.
10Type dm and go to the Maintenance Menu.
11Select Uninstall (D)isk Manager.
12Select the correct drive to uninstall.
When the uninstall is complete, exit Disk Manager and reboot.
GENERALTROUBLESHOOTING
Basic Troubleshooting Techniques
Warning. Always turn off the computer before changing jumpers or unplugging cables and cards. Wear a ground strap or take other antistatic precautions while handling your drive.
If you have installed your drive and it does not function properly, perform the following basic checks:
•Verify compatibility. Verify that the host adapter and the drive are appropriately matched to each other and to your computer. Refer to relevant documentation for details.
•Check all cards. Verify that all cards are seated in their slots on the motherboard and are secured with mounting screws.
•Check all cables. Make sure all ribbon and power cables are securely connected. Ribbon cables are easily damaged, especially at the connector. Try a new cable or a known good cable. Make sure no socket pins were bent when the cable was inserted. For each cable, verify that pin 1 on the cable is aligned with pin 1 on the drive and host adapter. The edge-stripe on the ribbon cable is used to denote pin 1.
!Caution. Do not reverse-plug the power connector. This can damage your drive.
•Verify equipment configuration. Review the instructions in this guide and the host adapter installation guide, and make sure that all appropriate jumpers are installed, or removed, to suit your application.
•Check the power-supply specifications. If new devices are installed, your computer’s power supply may not support the new total power requirement. Consult your dealer.
•Verify the drive-type settings in Setup. The drive-type settings in Setup must not exceed the physical specifications of your drive. Also, the settings must not exceed the limitations set by the operating system and BIOS.
•Check for viruses. Before you use someone else’s diskette in your system for the first time, scan the diskette for viruses.
Advanced Troubleshooting
If you have performed the preceding basic checks but the problem persists, follow these guidelines for troubleshooting specific cases:
Thesystem doesnotrecognizethedrive.
•Check all cables.
•Make sure the power supply is adequate for system needs.
•Reboot the computer and make sure the drive motor runs. If the drive is very quiet, it may be difficult to hear its discs reach operating speed. Recheck all drive cables if the drive is not running.
•Verify that each drive has a drive-type value in Setup.
•Try rebooting your computer by pressing the CTRL, ALT, and DELETE keys simultaneously. If the drive is recognized after the warm boot, the computer BIOS setup test may be completing before the drive is ready.
One solution is to slow the processor speed during startup. If your computer has a turbo switch, set it to slow speed before turning the computer on. If there is no turbo switch, you may be able to use keyboard commands; see your computer manual for details. After the computer is up and running, return the processor to the fast speed.
Another solution is to warm-boot your computer after every power-on.
•Check for I/O address conflicts. To isolate the conflict, verify that the drive and host adapter are compatible with your computer by removing all the peripheral adapter cards (power must be off) except for the video card. Reinstall the drive and host adapter card and boot the computer. If this is successful, reinstall the other peripherals one at a time until the conflict occurs. After you have isolated the source of the address conflict, you can resolve the conflict by changing the I/O address of the peripheral that appears to cause the conflict.
•If you are booting from a diskette and Disk Manager installed your drive using DDO, the information in the boot record for the drive was not loaded. Make sure there is not a diskette in Drive A and reboot. If you want to boot with the diskette, follow the “Booting with a Diskette” instructions in column one.
The dealer partitioned and formatted the drive for you in the store, but the drive does not respond when you install it.
•Reboot the computer and make sure the drive spins up. Check all cables.
•Make sure the power supply has adequate power for your system.
•Make sure the DOS version the dealer used to partition and format the drive is the same version you have installed on your computer. If it isn’t, see your dealer.
•Verify the Setup drive-type values. You must install the drive
using the same drive-type values your dealer used to partition the drive.
•Check for I/O address conflicts between peripheral cards.
•Check for viruses.
Thescreen remainsblank when you power upthe 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.
•While the computer is powered down, remove the drive host adapter. If the screen turns on after you reboot, the host adapter may be incompatible or defective. If so, see your dealer.
The system hangs in FDISK or fails to create or save the partition record.
•Check all cables.
•The DOS utilities diskette may be corrupted. Try your backup DOS diskette.
•Make the partitions smaller.
•Change the interrupt jumper setting on the host adapter.
•Check for media defects at the beginning of the drive. Use CHKDSK, SCANDISK or a third-party surface scan utility.
•Some BIOSs have a Track 0 protection feature that protects Track 0 from viruses. This can cause FDISK to hang the system. You must disable this feature in Setup before you can use FDISK. See your computer reference guide for assistance. Be sure to re-enable this important feature when FDISK is done.
The system error message, “Drive not Ready,” appears.
•Check all cable connections. Make sure that pin 1 of the drive is connected to pin 1 of the hard disc controller or host adapter.
•Make sure the power supply is adequate for system needs.
•Reboot the computer and make sure the drive spins up.
The FDISK error message, “No Fixed Disk Present,” appears.
•Make sure the power supply is adequate for your system.
•Verify the Setup drive-type values.
•Check for I/O address conflicts.
The drive does not format to full capacity.
•Verify the drive-type values in Setup. One of the following problems may have occurred:
–The values may be set with an incorrect translation characteristic.
–You may have entered a parameter value that exceeds the physical capacity of the drive.
–You entered a translation characteristic that does not take full advantage of the drive’s capacity.
–The drive’s physical specifications exceed the translation limits imposed by the BIOS.
Note. If you reset the Setup drive-type values, you must partition and format the drive again.
•If you have partitioned the drive into individual logical drives, you may need to make the partitions smaller so that the computer can use all of the drive’s capacity.
•If your computer supports LBA mode, you may need to enable the LBA mode function in Setup to get the drive’s full capacity. Refer to your computer’s reference guide.
•You can use the Disk Manager software to install the drive.
The DOS messages “Disk Boot Failure,” “Non-System Disk” or “NoROMBasic–SYSTEMHALTED”appear.
•Reinstall the DOS system files using the DOS SYS utility.
•Check all cables.
•Use FDISK to verify that the primary partition is active.
•Check for viruses.
System error message, “HDD controller failure” appears.
•Confirm the jumper settings on the drive.
•Verify the Setup drive-type values.
