======================================================================
This document gives installation instructions for a software driver
used to run Seagate SCSI DAT tape drives on Microsoft Windows NT 4.0
Intel platforms. This driver works with Intel 386, 486, Pentium
computers. It is required if your drive is labeled "Seagate", and has
an "STDxxxxx" part number.
This STDAT4.SYS driver differs from the 4MMDAT.SYS driver, supplied
with Windows NT 4.0 as follows:
* STDAT4.SYS recognizes Seagate model STDxxxxx tape drives. These
models return "SEAGATE DAT" data in response to a SCSI Inquiry
command.
* Timeouts are increased to 15 minutes for Read, Write, Write
Filemarks, Space, Locate, Erase(short), and Rewind operations.
Longer timeouts are only needed when a tape drive performs an error
recovery procdure because of a difficulty reading a tape. Old
timeout values ranged from 6 to 8 minutes.
If you did not receive this file on a diskette or CD-ROM, you must
create an installation diskette first. See the section below titled
"Installation Overview" for instructions.
======================================================================
SCSI DAT Device Driver Installation
-----------------------------------
Install the STDAT4.SYS device driver using this procedure:
For Windows NT 4.0:
1. If you are installing from CD-ROM, locate the STDAT4 directory
containing the file OEMSETUP.INF. Remember the directory's
<CD-drive-letter>:\<path>.
Otherwise, if you are installing from diskette, insert the
diskette, labeled as follows, into the floppy drive:
"Seagate DAT Tape Driver v1.08
for Windows NT 4.0 Intel Platform"
2. Start up the tape device driver installation program by selecting
'Start' -> 'Settings' -> 'Control Panel',
then double clicking the 'Tape Devices' icon.
3. Select the 'Drivers' tab.
4. In the 'Installed Driver' box, click the 'Add...' button.
5. In the 'Install Driver' box, click the 'Have Disk...' button.
6. You will see a 'Install From Disk' box message --
'Copy from manufacturer's files from: <source_path>'.
If you are installing from CD-ROM, set the <source_path>
to the <CD-drive-letter>:\<path> containing the file
OEMSETUP.INF remembered in step 1,
then click the 'OK' button.
Otherwise if you are installing from a floppy diskette, set
the <source_path> to 'A:\' (or your floppy drive letter),
then click the 'OK' button.
7. In the 'Install Driver' box's 'Tape Devices' list, you will see --
'Seagate DAT (stdat4.sys)'.
Select the device model number which is the closest match to the
label on your tape drive then click the 'Install' button.
Note. This choice is not critical.
8. If you see a 'Windows NT Setup' box with the message --
'The driver(s) for this Tape Device are already on the
system. Do you want to use the currently installed driver(s)
or install new one(s).',
click the 'New' button.
9. You may see a 'Windows NT Setup' box with the message --
'Please enter the full path to the Seagate Tape device files.
Then choose Continue.
<source_path>'.
If you are installing from CD-ROM, set the <source_path> to the
directory remembered in step 1. To this appended either \I386
for Intel computers, or \ALPHA for DEC Alpha computers. That is,
set the <source_path> to
<CD-drive-letter>:\<path>\I386
then click the 'Continue' button.
Otherwise if you are installing from a floppy diskette, set the
<source_path> to
'A:\I386'
then click the 'Continue' button.
10. In the 'System Settings Change' box message, you will see --
'You must restart your computer before the new
settings will take effect.
Do you want to restart your computer now?'.
Remove the driver installation diskette, then click 'Yes' to
shut down and restart the system.
The Seagate DAT Tape Driver is now installed and ready to use.
You may want to use the 'Administrative Tools' -> 'Backup' applet to
verify correct tape drive operation.

Installation Overview
---------------------
Use this general procedure to install a tape drive in the computer:
* Create a driver installation diskette from the file STDAT4.EXE.
* Configure the tape drive's switches and install the tape drive
in the computer.
* Install the tape driver from the Seagate tape driver installation
diskette.
* Reboot the system and verify correct operation.
======================================================================
Creating an Installation Diskette from the File STDAT4.EXE
----------------------------------------------------------
This procedure creates a tape driver installation diskette.
It assumes you have downloaded the file STDAT4.EXE to your system.
You also need formatted, empty diskette. STDAT4.EXE is a self-
extracting 16-bit WinZip program.
Note. If you already have a driver installation diskette labeled
"Seagate SCSI Travan Tape Driver v1.08
for Windows NT 4.0 Intel Platform", skip this
procedure.
1. Label the diskette:
"Seagate SCSI Travan Tape Driver v1.08
for Windows NT 4.0 Intel Platform".
2. On a Windows 3.1x, 9x, or NT, run STDAT4.EXE, open Windows
Explorer or Program Manager as appropriate.
3. Locate the down-load directory containing STDAT4.EXE.
4. Double click STDAT4.EXE to start the self-extractor.
5. You will see a dialogue box titled
WinZip Self-Extractor [STDAT4.EXE].
6. In the Unzip To Folder field, set your floppy drive
letter (for example A:).
7. Click the Unzip button.
8. You will see "3 file(s) unzipped successfully", then click OK.
9. Click Close
This extracts files and creates the driver installation diskette
with the following files (where A: is the floppy drive letter):
A:\STDAT4.TXT This document
A:\OEMSETUP.INF Setup information
A:\I386\STDAT4.SYS Seagate DAT tape driver for Intel
10. You may want to write protect the diskette.
This completes the installation diskette creation procedure.
Return to "SCSI DAT Device Driver Installation" above.
======================================================================
DAT Drive Hardware Configuration
--------------------------------
Please pay attention to these hardware configuration recommendations
for Seagate and Conner DAT tape drives:
* Shut down the system and turn power off before installing or
configuring hardware.
* Select a tape drive SCSI ID that does not conflict with the other
devices connected to the SCSI cable. Usually SCSI ID 4, 5, or 6
are good choices. Normally, hard discs are configured in
ascending order starting with SCSI ID 0 and the SCSI host adapter
is set to the SCSI ID 7 or 15.
* Your SCSI host adapter should be configured to 'Enable
Disconnect' for all SCSI device IDs. It is especially critical
that the SCSI adapter be configured to 'Enable Disconnect' for
the tape drive's device ID. If not, then accesses to the SCSI
hard disc can timeout because they cannot gain access to the SCSI
bus during long duration tape commands such as Rewind or Seek to
End-of-Data. If you have an Adaptec SCSI Host Adapter, you may
be able to set the 'Enable Disconnect' configuration by entering
<Ctrl><A> to enter the Adaptec BIOS during boot. Consult your
SCSI host adapter manual.
* The SCSI cable must be correctly electrically terminated at both
ends and only at the ends. Forms of cable termination vary.
Termination may be built into the cable end or ends. Termination
may be in the form of a terminator plug which is either plugged
into the end of the cable or plugged into a pass through
connector, if present, on the SCSI device attached to the end of
a cable. Many SCSI devices provide termination as a selectable
function which can be enabled, via jumper or switch, when the
device is connected to the end of the cable.
SCSI devices, in the middle of the cable daisy chain, should have
both terminators and termination power disabled. Most Seagate
DAT drives may be used to terminate the end of a cable by setting
the jumpers for 'ACT. TERM' (active termination) and 'TERM PWR'
(termination power). To disable the termination function, park
the jumpers by letting them hang on a single pin.
Consult the hardware documentation for your SCSI adapter and other
SCSI devices for more configuration and termination information.
======================================================================
Removing the Tape Driver from the System Configuration
------------------------------------------------------
This procedure removes the STDAT4.SYS driver from the system
configuration, but does not delete driver files.
1. From the desktop, click
'Start' -> 'Settings' -> 'Control Panel',
then double clicking the 'Tape Devices' icon.
2. In the 'Tape Devices' box, select the 'Drivers' tab.
3. In the 'Installed tape drivers are listed below' list,
highlight the entry that contains
'Seagate DAT (stdat4.sys)',
then click the 'Remove' button.
4. You will see a 'Remove Driver' box message --
'Are you sure you want to remove this driver?'
then click the 'Yes' button.
5. In the 'Tape Devices' box, click 'OK'.
6. Shutdown and restart the system.
The SCSI DAT tape driver is now removed from the system
configuration.
======================================================================
Uninstalling Tape Driver Files
------------------------------
To completely uninstall the tape driver including deleting the driver
files follow these steps:
1. Follow the instructions in section "Removing the Tape Driver
from the System Configuration" above.
2. Using Windows NT Explorer or an MS-DOS command prompt,
delete the tape driver file
C:\WINNT\SYSTEM32\DRIVERS\STDAT4.SYS.
Note. C:\WINNT\ is the directory in which Windows NT is
installed. It may be different on your system.
3. In the directory C:\WINNT\INF\ identify, for removal, any
OEM*.INF and corresponding OEM*.PNF which were created during the
STDAT4.SYS driver installation. Where '*' is an integer. For
example OEM0.INF, OEM1.INF, etc (and corresponding OEM0.PNF,
OEM1.PNF, etc). OEM*.INF files contain ASCII text instructions
used by Windows NT Setup to add and remove drivers. For each
OEM*.INF, setup creates a corresponding OEM*.PNF file.
CAUTION: There may be OEM*.INF (and corresponding OEM*.PNF)
files installed for other (non-tape) device drivers. Do NOT
delete these files.
To identify the OEM*.INF and corresponding OEM*.PNF files
associated with STDAT4.SYS from an MS-DOS command prompt, use
these commands:
cd C:\WINNT\INF
findstr /m /i stdat4.sys oem*.inf
Findstr will display a list of zero or more files. For example:
oem0.inf
For this example, delete both OEM0.INF and OEM0.PNF.
An alternate method for locating OEM*.INF (and corresponding
OEM*.PNF) files associated with STDAT4.SYS is to examine the
final line of each OEM*.INF file with an editor such as
NOTEPAD.EXE. If the final line of the .INF file contains the
driver file name "stdat4.sys", delete the .INF file and its
corresponding .PNF file. For example, if the final line of
OEM0.INF is similar to:
stdat4 = 1,stdat4.sys , SIZE=21536
then delete both OEM0.INF and OEM0.PNF.
The SCSI DAT Tape Driver files are now completely removed.
======================================================================
Important Notes
---------------
Tape Drive Firmware Version Determination
You can find the tape driver firmware revision using the
'Backup' applet.
1. Start the 'Backup' applet using
'Start' -> 'Administrative Tools' -> 'Backup'.
2. From the menu bar, select
'Operations' -> 'Hardware Setup...'
3. This opens the 'Hardware Setup' which looks something like ...
'Tape Drive
Scsi 0, Bus 0, ID 4, Lun 0, Seagate STT8000N 3.12'
The last field in the Tape Drive description (3.12 in this example)
is the firmware revision.
Examining Tape Device Driver Start Status
If you wish to examine whether certain tape related device drivers
are started, use the 'Devices' window.
To start the 'Devices' window, click the following:
Start -> Settings -> Control Panel -> Devices.
The following shows how the 'Device' entries of interest are set
when drivers are operating correctly:
Device Status Startup
------ ------- -------
<scsiadapter> Started Boot
stdat4 Started System
Examining the Version of 'stdat4.sys'
1. Start 'Windows NT Explorer'.
2. Highlight the file C:\Winnt\system32\drivers\stdat4.sys.
3. From the menu bar, select File -> Properties.
4. In the 'stdat4.sys Properties' box, select the 'Version' tab.
You should see 'File version: 4.00.Seagate.1.08'.
Events 9 and/or 11 in Event Viewer with a SCSI tape and SCSI hard disc
If you are experiencing tape device errors during backup or restore
operations and seeing these events in
Administrative Tools -> Event Viewer
'Event ID: 9 Description: The device, \Device\ScsiPort0, did
not respond within the timeout period.', and/or
'Event ID: 11 Description: The driver detected a controller
error on \Device\ScsiPort0.',
the cause may be that the SCSI adapter is not configured to
'Disconnect' the tape drive from the SCSI bus. When the SCSI bus
is not disconnected during a long duration tape command, such as
Rewind, then disc access commands time out waiting to get access
to the bus.
If you have an Adaptec 1542C controller, 'Enable Disconnect' should
be set to 'Yes' (the recommended default for all SCSI devices) at
least for the tape drive. Typically this configuration can be set
by entering the Adaptec BIOS Setup using <Ctrl><A> during the boot
process.
