Special Information for Windows 3.1 Users

 

If you encounter a problem while installing or
using your Zip® drive, check this section for help.

To avoid damage to your computer, disconnect all electrical connections before connecting or disconnecting cables.

 

The green activity light on the Zip® drive does not turn on.

  1. Make sure the computer is receiving power.
  2. Make sure the power cable connection to the Zip Internal drive is secure.
  3. Make sure there is a disk in the drive.

 

The Zip® drive is not assigned a drive letter,
or the Iomega software cannot find the Zip drive.

NOTE: These steps have already been performed by your computer's manufacturer. Iomega does not recommend that you follow any of these procedures unless your computer's original configuration has changed.

  1. Make sure PIN 1 is properly connected on all IDE interface connections. The stripe on the interface cable should align with PIN 1 on each connection. If the cable does not have a keyed connector, make sure the connector has not shifted by a pair of pins.
  2. Make sure the Zip Internal drive is configured correctly.
  3. If there is another drive on the same IDE channel, make sure it is also properly configured. Refer to the documentation that accompanied the other IDE or ATAPI drive for configuration information (often this information is on the drive case). If you cannot locate the documentation, contact the manufacturer of the drive.
  4. Make sure BIOS support for the Zip Internal drive is disabled in the computer’s CMOS setup. Note that this may require turning off autodetection for the Zip Internal drive. Refer to the Owner’s Manual for the computer if you need instructions on disabling autodetection.

    NOTE: This step may not be applicable to your system. Please check your system's reference manual.

    If you are unable to disable BIOS support for the Zip drive in the CMOS setup and the Zip Internal drive does not appear on the system, the computer may have an incompatible BIOS that does not correctly understand removable internal drives. You may be able to solve the problem by obtaining an updated BIOS from the computer manufacturer. If an updated BIOS is not available, it may be possible to install the Zip Internal drive successfully using an add-on IDE card.
  5. Make sure the software drivers for the Zip Internal drive are correctly installed on the computer system. The necessary drivers are included with the Iomega software package. Carefully follow the installation instructions given for the computer’s operating system.
  6. Some IDE hard drives do not work properly unless they are in a certain position on the IDE cable. You may need to reverse the position of the master drive, such as a CD-ROM, and the Zip Internal (slave) drive on the cable for the drives to work properly.

    NOTE: Your computer's manufacturer may have set your Zip drive to Cable Select. If your drive is set to Cable Select, Iomega recommends that you do not change that setting.
  7. If the computer still does not recognize the Zip Internal drive, it may be that the existing IDE master drive does not allow access to a slave drive on the same cable. Try installing the Zip Internal drive on the secondary IDE channel.

    NOTE: Your computer's manufacturer may have already installed your Zip drive on the secondary IDE channel.

 

Computer does not recognize a slave drive
connected to the same IDE connection with a
Zip® Internal master drive.

  1. Make sure PIN 1 is properly connected on all IDE interface connections. The stripe on the interface cable should align with PIN 1 on each connection. If the cable does not have a keyed connector, make sure the connector is not shifted by a pair of pins.
  2. Make sure the slave drive is correctly jumpered as a slave. Refer to the documentation that accompanied the slave drive for configuration information (often this information is on the drive case). If you cannot locate the documentation, contact the manufacturer of the drive.
  3. Some IDE hard drives do not work properly unless they are in a certain position on the IDE cable. You may need to reverse the position of the slave drive and the Zip Internal (master) drive on the cable for the slave drive to work properly.

 

Data transfer problems or drive operation is erratic.

NOTE: These steps have already been performed by your computer's manufacturer. Iomega does not recommend that you follow any of these procedures unless your computer's original configuration has changed.

Make sure the Zip Internal drive is electrically grounded. If the drive bay mounting screws do not make contact with a direct metallic path to the Zip drive chassis (for example, if you are using a plastic carrier to mount the drive in a 5 1/4” bay), then you need to provide a grounding strap. The grounding strap should be a wire from the ground lug on the right side of the drive by the power connector to a solid, metal connection on the computer chassis.

 

You want to change the drive letter assigned
to your Zip® drive, or installing the Zip drive
changes other drive letter assignments on
your system.

Drive letter assignments are controlled by the operating system – in order to change a drive letter assignment, you must work with the procedures required by your computer’s operating system.

Refer to the information in the electronic manual on the IomegaWare CD. To access the manual, insert the IomegaWare CD into the computer’s CD-ROM drive and double click on the filename in Windows File Manager. Follow the instructions on the first panel of the manual to jump directly to the section on DOS drive letter assignments.

 

You can’t change the drive letter assigned
to your Zip® drive.

Make sure BIOS support for the Zip Internal drive is disabled in the computer’s CMOS setup. This may require turning off autodetection for the Zip Internal drive. Refer to the Owner’s Manual for the computer if you need instructions on getting into the CMOS setup and disabling autodetection.

 

Hard drive does not appear as an option
in Copy Machine when using Windows 3.1.

When using Copy Machine in Windows 3.1 or Windows for Workgroups 3.11, turn off 32-bit disk and/or file access. (This option is available when changing virtual memory options under 386 Enhanced in the Windows Control Panel). If 32-bit access is not turned off, your hard drive will not appear for selection in the Copy Machine window.
