- 1. Installing Ditto Tools After Other Backup Programs
- -------------------------------------------------------------------------------------
- You may experience difficulty running Ditto Tools
- if some device files from other backup programs are
- found in your SYSTEM.INI file. If you can't start
- Ditto Tools, try commenting the following devices out
- of your SYSTEM.INI file:
-
- CMSWTAPE.386
- CMSDTAPE.386
- CPBVXD.386
- FASTBACK.386
- IRW286.DRV
- NOVABKP.386
- VIRWT.386
- VITD.386
- DCVXD.386
-
- To do this:
-
- 1. Open the SYSTEM.INI file using a text editor.
- 2. Search for the device name(s), e.g., DEVICE=CPBVXD.386
- 3. Type a semicolon (;) at the beginning of the line.
-
-
- 2. Do Not Run Ditto Tools with Boot-Disk Creator
- -------------------------------------------------------------------------------------
- Do not run Ditto Tools and the boot-disk creator
- at the same time. Floppy drives cannot be used
- while the product is running.
-
-
- 3. Setup Disk Space Estimates
- -------------------------------------------------------------------------------------
- To insure that the user always has enough disk space to
- install Ditto Tools, the Setup program displays the
- maximum amount of space that may be required for installation.
- This estimate is affected by the actual options selected
- for install and also includes some space that is necessary
- in order to run the setup program.
-
-
- 4. Video/DMA Conflict Problems
- -------------------------------------------------------------------------------------
- Ditto Tools uses direct memory access (DMA) channels to
- read and write data. Sometimes using a tape device that is
- connected to the floppy controller causes conflicts with
- the Windows 3.1 video drivers.
-
- During the compatibility test, Ditto Tools determines if
- your system has a video/DMA conflict and if so, goes through
- a series of tests in an effort to ensure your system runs
- reliably with Ditto Tools. After each test a message will
- inform you that tests are still being performed. If
- Ditto Tools has attempted every test and your
- system will still not work reliably, a message will inform
- you of the problem.
-
- NOTE: If you experience video/DMA conflicts, try disabling the
- Video Caching option (sometimes referred to as Video Shadowing)
- in your CMOS setup.
-
- If your system locks up when using the backup program, switch to the
- Windows Standard VGA driver. If the Windows Standard VGA driver
- works, contact your video board manufacturer for an updated driver.
-
-
- 5. Laptop/Notebook Video Conflicts
- -------------------------------------------------------------------------------------
- Some laptop and notebook computers may have video conflicts
- that cause the tape drive to move the tape back and forth
- excessively ("shoe-shining").
-
- If you experience this, try minimizing the Ditto Tools icon
- and making the Program Manager window active and moving it over
- the top of the icon while the program is writing to or reading
- from the tape. The Ditto Tools window will activate itself
- when the backup or restore is finished, and this action should
- speed up your session.
-
-
- 6. Power Management Conflicts
- -------------------------------------------------------------------------------------
- Some Desktop computer systems and laptops have power
- management systems that take a "snapshot" of RAM and
- store it on the hard drive when they power down. This
- may create a conflict if it occurs during a backup or
- restore or a tape formatting operation.
-
- When using Ditto Tools, it is recommended that you turn
- OFF all power management features. If you're using
- a laptop, avoid running power management features
- by using an outlet rather than batteries.
-
-
- 7. Reading Irwin AccuTrak Tapes
- -------------------------------------------------------------------------------------
- Your Iomega drive can read both QIC-40/-80 and Irwin
- AccuTrak tapes. To read an Irwin tape, you must first rebuild
- a catalog for the tape. Select Rebuild from the Catalog
- menu. When the rebuilding process is complete, you can
- load and use the catalog to restore files from that tape.
-
- NOTE: You cannot format or write to AccuTrak tapes with your
- Iomega drive.
-
-
- 8. Maximum Parallel Port Cable Length
- -------------------------------------------------------------------------------------
- Your parallel port tape drive should be connected directly to
- your system's parallel port. If you use the pass-through
- connector on the drive to connect a second device such as a
- printer, the maximum cable length for both devices is
- approximately 10 feet (3 meters).
-
- If you have difficulty using your tape drive when a second
- device is connected to the pass-through connector, disconnect
- the second device and its cable while using the tape drive.
-
- If you experience data loss when using a printer connected to
- the pass-through connector, shorten the printer's cable if
- possible or disconnect the tape drive while printing.
-
-
- 9. IRQ Conflicts
- -------------------------------------------------------------------------------------
- You may experience a conflict in IRQ selection if you are
- configuring a parallel port tape drive on a system that
- includes a sound card. SoundBlaster cards and compatibles use a
- default IRQ of 7, which is also used by a printer port (LPT1).
- If this conflict occurs, you can:
-
- * Change your sound card's IRQ if possible. Some cards do
- not allow this change and some games may not work
- correctly.
-
- * Check your system documentation to see if your parallel port
- can be configured to use a different interrupt.
-
- Devices that may conflict with printer port interrupt:
-
- Sound Cards
- Scanner Cards
- Network Cards
- Bus Mice
- Other printer ports
- Other devices
-
- IRQ usage can be determined by using the Microsoft Diagnostics
- Program. Exit Windows and type MSD at the DOS prompt. Note that MSD
- cannot always diagnose printer port IRQ conflicts. Printing does not
- require a hardware interrupt and will function normally even if an
- interrupt conflict exists.
-
- Symptoms of an IRQ conflict include Ditto Tools not
- finding the tape controller and network problems when
- backing up to tape.
-
-
- 10. Potential Conflict with Screen Savers
- -------------------------------------------------------------------------------------
- Some screen savers will not activate while a
- backup, compare, or restore is running and
- Ditto Tools is minimized. For optimum
- performance, we recommend that you disable your
- screen saver while using Ditto Tools.
- However, if you wish to use your screen saver,
- you must first make sure Ditto Tools
- is not minimized.
-
-
- 11. NetWare Files With an Execute Only (X) Attribute
- -------------------------------------------------------------------------------------
- NetWare files with an execute only (X) attribute will not be
- backed up, compared, or overwritten during a restore.
-
-
- 12. Files Not Backed Up by Ditto Tools
- -------------------------------------------------------------------------------------
- Ditto Tools does not log or back up a number of files
- to avoid potential system conflicts if they are restored.
-
- Compressed Volume files:
-
- DBLSPACE.0??
- DRVSPACE.0??
- STACVOL.*
-
- Windows swap files:
-
- 386SPART.PAR
- WIN386.SWP
-
- NetWare System files:
-
- BACKOUT.TTS
- NET$SPL.QUE
- NET$MSG.SYS
- DIRSTAMP.SYS
- NET$OBJ.SYS*
- NET$PROP.SYS*
- NET$VAL.SYS*
- NET$BIND.SYS*
- NET$BVAL.SYS*
- SYS$LOG.ERR
-
- * These NetWare bindery files will be backed up or restored
- only if you are logged on to a server as Supervisor. See your
- User Guide for more information.
-
- Additionally, Ditto Tools will not back up a number of
- temporary files used by the program when these files are found
- in the program's directory.
-
-
- 13. Formatting Tapes on 386 Machines
- -------------------------------------------------------------------------------------
- If you encounter difficulties formatting tapes on a slower 386
- machine or receive a message stating "The tape controller is not
- responding correctly," make sure your turbo switch is on.
-
-
- 14. Hardware Compression Not Supported
- -------------------------------------------------------------------------------------
- Ditto Tools for Windows, Version 5.0, does not support
- the hardware compression function found on some high-speed
- controller cards.
-
-
- 15. Restoring Files with NetWare Delete Inhibit or Rename
- Inhibit Attributes
- -------------------------------------------------------------------------------------
- During a Restore, you cannot overwrite files which have
- the NetWare Delete Inhibit (D) or Rename Inhibit (R)
- attribute set. To restore these files, you must first manually
- remove the Delete Inhibit or Rename Inhibit attribute.
-
-
- 16. Performance Issues on QIC-3020 Parallel Port Tape Drives
- -------------------------------------------------------------------------------------
- If you have a QIC-3020 Parallel Port tape drive you may
- experience a performance limitation, especially on
- systems with unidirectional parallel ports. This combination
- may not transfer data from the tape drive to the system fast
- enough to allow the tape to run continuously, or "stream."
- However, if you reformat the tape using the QIC-3010 format,
- the tape will run at half the speed of a QIC-3020 and stream
- more of the time. This will result in faster net restore times
- and less wear on the tape drive, but will cut the tape's
- capacity in half.
-
-
- 17. Controller Conflicts
- -------------------------------------------------------------------------------------
- The Promise 2300 EIDE VLB controller must run in fast
- mode (/f parameter) in order to work with floppy tape drives.
-
-
- 18. Possible Video Conflicts
- -------------------------------------------------------------------------------------
- Problems have occurred with various video drivers and the video
- compatibility test in Windows. If your software hangs during the
- Compatibility Test, try to get an update of the video driver
- from the card manufacturer. Conflicts have occurred with Diamond
- Stealth 64 and ATI Ultra Mach 32/64 cards.
-
-
- 19. EZ-Drive Disk Manager
- -------------------------------------------------------------------------------------
- The following information applies to systems
- with high-capacity hard drives using the Micro
- House EZ-Drive disk manager:
-
- Before starting Ditto Tools for Windows, make
- sure that the Micro House EZ-Drive Virtual Driver
- is installed by running the SETUP.EXE program on
- the EZ-Drive installation diskette. This setup program
- adds the line "device=MH32BIT.SYS" to the [386Enh]
- section of your SYSTEM.INI file.
-
- Then follow the steps below:
-
- 1. Click the Windows Control Panel's "Enhanced" icon.
- 2. Select the Virtual Memory... button.
- 3. Select the Change>> button.
-
- Ensure the "Use 32-Bit Disk Access" check box is checked.
- This check box must remain checked in order to use
- Ditto Tools for Windows.
-
-
- If you continue to encounter problems using Ditto Tools
- for Windows, and if you are using a QIC floppy tape or
- parallel port tape drive, follow the steps below:
-
- 1. Open Ditto Tools.
- 2. Select the Configure button.
- 3. Select the Settings button.
- The Settings dialog appears.
- 4. Select the Most Compatible setting in
- the DMA Operation combo box.
-
- This results in lower performance, but may be necessary on some
- systems for proper operation.
