I tried other drivers on this site. But this is the one that worked for me.
Iomega split their driver/tools file up. First run this program to install the driver & Win2000 will recognize your Zip drive. It may ask you to uninstall some of your ZipWare to do this. After installing the driver, go to www.iomega.com/software/featured/ioware_apps.html to download any ZipWare apps you've deleted.
