SEAGATE TAPE DIAGNOSTIC UTILITY VERSION 3.0 
===========================================

CONTENTS:
1. Loading Windows NT 4.0 tape drivers
2. Closing backup applications
3. Using full-length/standard tapes
4. Long test times on ATAPI drives under Win95/98
5. If your drive fails the testing


1. Loading Windows NT 4.0 tape drivers
=======================================
For maximum compatibility, the Seagate Tape Diagnostic utility uses the native 
Windows drivers from Microsoft.  In Windows 95/98, this is normally not a problem.  
However, in Windows NT 4.0 if the diagnostic software does not detect your tape 
drive, it may be because the proper NT tape driver has not been loaded. 

To determine whether the native NT device driver is installed for your specific 
drive, do the following:
* Open Tape Devices from within your system's Control Panel.
* Select the Drivers tab.  Is the device driver for your tape drive installed?  
If not...
* Select Add.  Two list columns will appear:
* On the Manufacturers list, select (standard tape drives).
* On the Tape Drives list, select the appropriate tape device and press OK. 
(See the list below.) Note:  You may need your Windows NT CD.

The following Seagate drivers are supported.  If the driver you need does not 
appear on your list, you can download it from the Tape Resource CD or 
www.seagate.com/tape, which also includes complete loading instructions.

sttscsi4.sys - Travan SCSI drives
qic157.sys - Travan ATAPI/IDE drives
stdat4.sys - DAT drives
sgteait.sys - AIT drive

2. Closing backup applications 
===============================
Due to Windows architecture, only one software application can access a 
tape drive at a time.  Before running the Tape Diagnostic, be sure to close down 
your backup application so that it releases the tape drive.  For desktop software 
(Windows 95/98/NT Workstation), simply exit the program.  Server software is more 
complicated.
* On Backup Exec for NT servers, run the file bestop.bat to stop the Windows service.  
To resume the service after using the diagnostic, run bestart.bat.  These files are 
located on the Backup Exec 7.0 and 7.2 CDs under \winnt\utils. On Backup Exec 7.3 
and above, they are automatically installed on the system in the Backup Exec directory. 
* On ArcServeIT for NT servers, go into Control Panel and double-click on Services. 
Highlight each ArcServe service, one at a time, and click on Stop. When finished, 
click on Close. To resume the services after using the diagnostic, repeat the 
process, but click on Start for each service.

3. Using full-length/standard tapes
====================================
The Seagate Tape Diagnostic utility assumes you are using "native" tapes with 
each drive (Travan 8GB with TR-4, 125 meter with DDS-3, etc.).  If you use 
other tapes, the error counts and capacity checks will be inaccurate.

4. Long test times on ATAPI drives under Win95/98
==================================================
In order to guarantee accuracy in testing ATAPI tape drives under Windows 95/98, 
it is necessary for the software to slow down the write process by downshifting 
the tape drive.  Please be patient if you are using a large data size on a 
Read-Write test.

5. Troubleshooting tips
=======================
* Make sure the tape drive is receiving power.
* Verify that the interface cable is securely attached to both the tape drive 
and the adapter card or computer motherboard.
* Make sure that any adapter card (such as a SCSI card) is completely inserted 
into the computer system and that jumpers or switches are set correctly.
* Run the diagnostics that came with the adapter card (the card may not be 
functioning properly).
* If your drive fails a read-write test, be sure to repeat the test with 
other media and clean the head at least once.
* Make sure you are using the proper media type (125 meter tape on DDS-3, 
Travan 8GB on TR-4, etc.)
