    If the Iomega Hard Drive letter appears, you can now use the drive.

    If the Iomega Hard Drive is still not detected, continue with the next step.

Note: If you are not using a USB hub, proceed to STEP FIVE

1. Disconnect the Iomega Hard Drive from the USB hub.
   
   
2. Try connecting the Iomega Hard Drive directly to one of the USB connectors on the computer.
   
   
3. Restart the computer.
   
   
4. Double-click the My Computer icon to see if the Iomega Hard Drive is detected.
   
   

   If the Iomega Hard Drive is detected, you can now use the drive.

   If the Iomega Hard Drive is still not detected, continue with the next step.

1. Right-click the My Computer icon and select Properties.
   
   
2. Click the Device Manager tab.
   
   
3. Double-click the computer icon at the top of the Device Manager window.
   
   
4. Click the View Resources tab.
   
   
5. Select the Interrupt Request (IRQ) option.
   
   
6. Ensure that the following list of Reserved and Default IRQ settings are present:
   
   

   Note: Reserved assignments are Universal and cannot be changed. Default settings are assigned by the hardware and can be shared or reassigned. The Reserved and Default settings should look something like the ones listed below. Systems may vary.

   00: (Reserved) System Timer

   01: (Reserved) Keyboard

   02: (Reserved) Programmable interrupt controller

   03: (Default) Communications Port (COM 2)

   04: (Default) Communications Port (Com 1)

   05: (Default) Sound Card or LPT 2

   06: (Reserved) Standard Floppy Disk Controller

   07: (Default) Printer Port LPT 1

   08: (Reserved) System CMOS/real time clock

   09: (Default) System device connected in a PCI slot

   10: (Default) System device connected in a PCI slot

   11: (Default) System device connected in a PCI slot

   12: (Default) PS/2 Compatible Mouse Slot

   13: (Reserved) Numeric data processor

   14: (Default) Primary IDE Controller

   15: (Default) Secondary IDE Controller

7. Scroll through the list of IRQs and locate the IRQ for the USB controller. It is usually located between IRQ 09 and 11.
   
   
8. For the USB controller, there should be two items listed:
   
   
   1. PCI to USB Universal Host Controller or Adapter
      
      
   2. IRQ Holder for PCI Steering
      
      
9. If there are additional devices on the same IRQ as the USB controller (such as Modems, Network Cards, Audio devices, Video devices, PCMCIA controllers, etc.) an IRQ conflict is possible. Many times two or more devices can share an IRQ without conflicting. Other times IRQ sharing is not possible, which will result in computer lockups and device malfunctions.
   
   
10. You may contact the computer manufacturer for more information about conflicting IRQs or you can physically remove any conflicting card or device from the computer. If your do not want to remove the conflicting card or device from your computer, please use the following steps to resolve IRQ conflicts by creating a separate boot profile.
    
    
    1. From the open System Properties window, select the Hardware Profiles tab. Original Configuration should be highlighted.
       
       
    2. Click the Copy button.
       
       
    3. In the text box, type a new Profile name such as Iomega Hard Drive.
       
       
    4. Turn off the computer.
       
       
    5. Turn the computer back on.
       
       
    6. Windows will now give you the option to select the Boot Profile you would like to use. Choose the profile that you just created above (Iomega Hard Drive).
       
       
    7. Right-click the My Computer icon and select Properties.
       
       
    8. Click the Device Manager tab.
       
       
    9. You will now need to disable the devices that are sharing the same IRQ by using the following steps.
       
       
       1. From the Device Manager, select one of the devices that are sharing the same IRQ as the USB Controller.
          
          
       2. Double-click the icon for that device.
          
          
       3. At the bottom of the Properties screen, click Disable this hardware profile to place a check mark in the box.
          
          
       4. Continue using the steps above to disable all of the devices that are on the same IRQ as the USB controller.
          
          
       5. Once you are finished disabling devices, restart the computer.
          
          
    10. Restart the computer and boot into the Iomega Hard Drive profile again.
        
        

        Note: When you want to use the Iomega Hard Drive, you will need to choose the profile that was created above (Iomega Hard Drive). For all other times, you will need to choose the Original Configuration boot.

    11. Double-click the My Computer icon to see if the Iomega Hard Drive is detected.
        
        

        If the Iomega Hard Drive is detected, you can now use the drive.

        If you are using a 40GB or 80GB Desktop (External) USB drive, the USB interface cable connection may be loose or there may be a problem with the interface cable. Please recheck the connection and if the drive is still not detected, please contact Iomega Technical support at http://www.iomega.com/support/contact/index.html

        If you are using any other Desktop (External) or Portable USB drive, please go to http://www.iomega.com/support/askiomega_options.html for additional troubleshooting options.
