On the following lists, if one step does not work, go to the next.
Quick Hardware Checklist:
1. Try another cartridge. If another cartridge mounts with no problem, then the original cartridge is probably defective.
2. Make sure that another SCSI device on the same bus is not trying to use the same SCSI ID. All SCSI IDs on the same bus must be unique.
3. Disconnect any external SCSI devices that you may have. If cartridges mount without the externals connected and each device has a unique SCSI ID, make sure that the external SCSI cables are double-shielded twisted pair and that the cables are less than six feet between devices.
Software Issues:
1. Check your Extensions Manager to see if the "HDT Extension" is set to load. If so try disabling it and restart. The HDT Extension sometimes tries to take control of Iomega drives, preventing cartridges from mounting.
2. Open your Extensions Manager and locate an item on the list called "Iomega Driver". If it is present put a check mark next to it by clicking on it one time. Restart your computer.
3. If the Iomega Driver is not in the Extensions Manager, then it needs to be installed. On the Power CD that came with your computer go to the Utilities folder, then Extensions, and you will see an Iomega Driver inside. Copy that to your hard drive and place it in the Extensions folder inside the System Folder. Restart your computer.
4. Open your Extensions Manager, open the "Set" menu, and select 7.5, 7.5.1, 7.5.2, 7.5.3, or 7.5.5 depending on the version of system software you are running. Locate the "Iomega Driver" and the "CD-ROM Toolkit" and put check marks next to these two items only. Restart your computer.
