                             TECHNICAL SUPPORT


TECHNICAL SUPPORT IS AVAILABLE FOR THIS PRODUCT.  HOWEVER, WE ASK FIRST
THAT YOU EXPLORE THE SUPPLIED DISKETTE-RESIDENT DOCUMENTATION FOR
POSSIBLE SOLUTIONS TO ANY PROBLEMS, AND TO HAVE THE PROPER INFORMATION
READY SHOULD A CALL TO TECHNICAL SUPPORT BE REQUIRED.

Before you call us for technical assistance, please do the following:

    1) If you are unable to load DISK MANAGER successfully after typing
       "DM" from the DOS prompt, you have a hardware problem. Follow the
       guidelines described below.  Also, refer to the file "HARDWARE.REF"
       for additional assistance.


    2) Check your hardware connections (disk cables, jumper settings, etc).
       DISK MANAGER will help identify a hardware problem. If the
       error message "NO HARD DRIVES INSTALLED" appears, or if DISK MANAGER
       is unable to recognize the presence of all attached hard disks, a
       hardware problem is likely.


    3) Execute DISK MANAGER DIAGNOSTICS to detect and correct cable
       connection, controller card or disk problems. Note that the disk
       scan test cannot be executed until the disk has been initialized.


    4) Read this file, the DM.REF file, and the HARDWARE.REF file for
       information that may be pertinent to your particular installation.
       Our technical support phone number is (800) 468-3472. When you call,
       we will need to know:


               A) Your computer type

               B) Your disk drive type

               C) The version number of DISK MANAGER (as displayed when
                  DISK MANAGER is loaded.

               D) Your DISK MANAGER serial number (as viewed when
                  DISK MANAGER is loaded from diskette).























                           DISK MANAGER FEATURES


THIS SECTION CONTAINS INSTRUCTIONS FOR THE AUTOMATED INSTALLATION
PROCEDURE ONLY. IF YOU NEED INFORMATION ON THE CUSTOMIZED INSTALLATION
PROCESS, SEE THE FILE "DM.REF", LOCATED ON YOUR DISK MANAGER DISKETTE.

DISK MANAGER by ONTRACK COMPUTER SYSTEMS is a software utility that
completely installs your fixed disk drive(s) for use with your IBM or
compatible personal computer system.

A complete disk installation requires low-level formatting, partitioning
and high-level formatting (preparation).  DISK MANAGER performs these
activities AUTOMATICALLY, with several additional features available. The
primary features of DISK MANAGER are as follows:

Automated Installation Capability - Invoke this utility by typing
       "DM (ENTER)" to initialize, partition and prepare a disk
       drive for use.

Customized Installation Capability - Provides the user with the ability
       to create a custom logical disk structure to meet specific
       requirements. This feature also allows the user to selectively
       change the write-protect status of any disk partition.

DOS Compatible - Operates under PC-DOS and MS-DOS. No alterations to
       the operating system are required.

Partitioning Capability - Permits up to 16 disk partitions per drive,
       so programs and program data can be organized for optimum disk
       utilization. Provides the capability of assigning partitions to
       separate users, thus providing additional data security. Simplifies
       the use of DOS by reducing the need for subdirectories. DISK MANAGER
       permits a boot partition as large as the DOS limitation of 32 MB.
       Non-bootable, DOS-compatible Write/Read partitions may be as large
       as 512 MB with DOS 3.X.

Increased Storage Capacity - Permits the attachment of disk storage up to
       512 MB per drive.

Multiple Operating System Capability - Up to four operating systems can
       exist on a single storage unit.

Reduced Back-up Time - Programs and data can be selectively backed-up due
       to the partitioned disk structure.

Write-Protect Capability - Provides selectable write-protect capability on
       each disk partition, preventing sensitive data from being destroyed.

Selectable Interleave For Each Partition - Allows the user to optimize the
       performance of the software that operates from each disk partition.

Variable Cluster Size and Root Directory Size - Allows the user to optimize
       the utilization of disk space.












                   AUTOMATED INSTALLATION PROCEDURE

This section contains the basic instructions for using DISK MANAGER's
automated installation procedure. These instructions apply for installing
any SEAGATE disk drive (having a ST412/ST506 or SCSI interface) in any PC-XT
or PC-AT (or 100% compatible) computer. If there is anything you do not
understand, or if you encounter a problem during installation, use the more
detailed instructions included in the DM.REF file on this diskette.

WE ASSUME THAT YOUR HARDWARE IS CONNECTED PROPERLY. TO EXECUTE THIS
PROCEDURE, YOU ONLY NEED TO KNOW WHICH MODEL SEAGATE DRIVE YOU HAVE, AND
HAVE THE DEFECT LIST FOR THAT DRIVE.

STEP 1: CREATE A BACK-UP DISKETTE

        For your convenience, DISK MANAGER is not copy-protected.
        Create a back-up diskette by formatting a blank diskette and
        copying the DISK MANAGER files onto it.

STEP 2: BOOT YOUR SYSTEM TO OBTAIN AN A> PROMPT

STEP 3: INVOKE DISK MANAGER'S AUTOMATED INSTALLATION UTILITY

        From the DOS A> prompt, enter:

        A>DM  <ENTER>             for monochrome display, or

        A>DM/C <ENTER>            for color display

        DISK MANAGER's automated installation utility will lead you
        through the entire disk installation process. On-line help is
        available every step of the way. To use on-line help, simply
        press the F1 key. There will be a prompt on your display to
        indicate when help is available.

        DISK MANAGER will:

              A) verify that the drive you intend to install can
                 communicate properly,

              B) prompt you to specify the drive model,

              C) optionally allow you to enter the defect list,

              D) prompt you for how the disk is to be partitioned,

              E) perform low-level format, partition the disk, perform
                 high-level format, and leave you with a bootable
                 hard disk.
