   1.  Getting Started
-------------------------------------------------------------
This product enables access to your tape drive from
Windows 95. You can now use your tape drive for file storage
and retrieval as if it were a hard drive or floppy disk.
A tape icon is displayed in the Taskbar's notification tray,
(located on the end of the Taskbar opposite the Start button)
when a tape is in the drive. Right-click this icon to display
the Tape menu. Double-click this icon to open the Toolkit, where
you can view the contents of your tape, open files, and move
files to and from tape.

This program automatically detects your tape drive.
However, if you need to remap your tape drive use the
System Properties dialog located in the Windows 95 Control
Panel.

Tapes must be formatted for Seagate Direct Tape Access use.
Refer to the on-line help for configuration and formatting
instructions.

Note: If you are running Arcada Backup for Windows 95
      version 1.0, upgrade to Arcada Backup for Windows 95
      version 1.1.



   2.  Special Considerations
-------------------------------------------------------------

   * Modifying files directly on tape can cause an inefficient
     use of tape space and may make delays seem excessive.
     When you want to edit a file stored on tape, move the file
     to your hard drive first, make changes, then move the file
     back to tape.

   * Although you can delete files from tape, be aware that space
     on tape is not reclaimed like it is on disks. You must format
     the tape before reclaiming space on tape.
     
     Caution: Formatting erases all data on the tape.

   * If using a backup program, you cannot write both backup sets
     and files written with Seagate Direct Tape Access on the same tape.

   * If you have created a shortcut to your tape drive in the SendTo
     folder or any other location and have remapped your tape drive
     since creating the shortcut, you must update the shortcut to point
     to your tape drive's new drive letter.

   * See your on-line help for additional considerations.



   3.  Performance Issues
-------------------------------------------------------------
   * Performance depends on various combinations including
     the type of drive, the controller, and the speed of
     your machine. On certain drives Seagate Direct Tape Access
     is capable of playing AVI, MOV, MPEG, and other types
     of video files directly from tape.

   * Files on tape can be used with applications. However,
     we do not recommend running software applications
     off the tape.

   * Do not run your backup software until your direct tape
     software has finished accessing your tape drive.

     Caution: Invalid drive settings can cause a General Failure.
              Refer to the Help on configuration.



   4.  Known Issues
-------------------------------------------------------------

   * If you are using an Archive Python DAT drive with a
     de-'magnetized' tape, Seagate Direct Tape Access cannot write
     to the tape or erase the tape. The drive reads the tape
     as damaged and reports a remaining capacity of 0.

   * If a 3020 tape is inserted in a QIC-80 drive,
     Seagate Direct Tape Access does not recognize the
     tape in the drive. When you select the tape drive
     in the Explorer, a message appears indicating
     that there is no tape in the drive.

   * If your tape drive is unable to estimate the amount
     of tape space used and the amount of tape space available,
     the program displays 250MB in the Properties dialog box.

   * Windows and DOS can only report up to 2GB of free space.
     If your tape can hold more than 2GB, this information
     will not be accurately reported until the amount of free
     space on the tape is less than 2GB.

   * QIC-113 Read Support only supports QIC tapes written by
     Seagate, Arcada, Conner, HP, and Colorado Memory Systems (CMS)
     backup products. In addition, files in password protected
     sessions, spanned sessions, or containing maximum path lengths
     will not be accessible using your direct tape software.

   * If you copy files to the tape until it is full, the Explorer
     presents a message indicating the tape (or disk) is full and
     files need to be deleted from the tape. However, deleting files
     from tape does not reclaim tape space. You must format the tape
     before reusing tape space.

   * This program does not support QIC-40 tapes.

   * Please make sure that your CONFIG.SYS and AUTOEXEC.BAT files do
     not contain duplicated DOS protected mode drivers, such as ASPI
     drivers (ASPI4DOS, BTASPI), CD-ROM drivers, or any other drivers
     that Windows 95 already provides. You should be using Windows 95
     drivers only.

   * The Adaptec AHA-1510B SCSI controller may cause sluggish performance.
     If you experience this problem, contact Adaptec for the latest
     mini-port driver.

   * Windows 95 does not allow sharing of DMA and IRQ lines between a high
     speed controller and the standard floppy disk controller. If you
     have conflicts, make sure you make these settings unique.
     If you receive an "interrupt not received" error message while using
     the 2 Mbps FC-20 high speed controller, try another IRQ other than
     IRQ 10 and IRQ 11.

   * On some PC's, the Windows 95 operating system software is unable to
     properly recognize and configure the IDE chipset, which controls the
     IDE hard disk, CD-ROM, and IDE tape drive. If this is the case,
     Windows 95 forces all accesses to IDE devices to occur
     sequentially, sometimes referred to as serialized access. Serialized
     access implies each IDE operation must complete before the next access
     can begin. Normally the delays caused by sequential operation are not
     apparent because hard drive and CD-ROM accesses complete quickly.
     However when using the IDE tape device, there are certain tape operations
     that require longer periods of time to complete, such as a tape retension.
     In such a case, a noticeable delay in accessing the other IDE devices occurs,
     giving the appearance the tape software has stopped reponding. In fact, the
     system is just waiting for the IDE tape operation to complete. If you
     experience these unusual delays when using the IDE tape device,
     it may be necessary to obtain a third party IDE controller card. A
     dedicated IDE controller such as the Acculogic IDE controller card can
     be purchased to resolve this problem.

   * In rare cases, a valid QIC-80, 3010, and 3020 tape may be reported as
     not readable by the drive. To access these tapes use the software
     that originally created the data.

   * Tape drives used with Seagate Direct Tape Access, cannot be used with
     Norton Disk Doctor, Norton UnErase, and other file system utilities.

   * Seagate Direct Tape Access does not support Windows 95 Eject PC feature
     when running on portable computers.

   * QEMM 8.00 software is incompatible with
     Seagate Direct Tape Access. If you are using QEMM version
     8.00, please contact Quarterdeck for
     the latest version of their software.

   * If you are running Seagate Direct Tape Access on
     a Windows 95 system using an FC-20 High-speed floppy controller
     and are using HP Colorado Backup for Windows 95,
     Seagate Direct Tape Access must be installed after
     HP Colorado Backup for Windows 95 in order for both programs to
     share the controller.  If you have already installed
     Seagate Direct Tape Access first, uninstall the program,
     reboot your system, and reinstall Seagate Direct Tape Access.

   * If you turn on your tape drive after Windows is running, you must
     reboot before Seagate Direct Tape Access can use the drive.

   * If your system is not responding and the tape is still spinning, do
     not manually remove the tape from the drive. Manually removing the
     tape from the drive may result in data loss. Rebooting or powering
     down your system at this time may also result in data loss. We
     strongly recommend waiting for the tape operation to complete,
     and then rewinding the tape prior to removal.

   * Sporadic SCSI bus resets can occur using an Adaptec 2940 adapter
     card with an ASPI minport driver that was shipped with the original
     version of Windows 95. A miniport driver fix is available from Adaptec.

   * Sending data to a printer that is connected to a tape drive can cause
     tape commands to fail.  If you experience problems using your tape drive
     after printing, try re-inserting the tape or rebooting your computer.

   * When you format a tape using a QIC-117 tape drive, your floppy
     disk is inaccessible.

   * Virus scanning software causes slow performance when overwritting
     files on your tape. To improve performance, disable virus scanning
     on the drive letter assigned to your tape drive.
