I have had my machine about 3 weeks, and had lots of problems with Iomega Zip drive. I finally got it working, the tools also. I did a system restore/saving original items and then installed Iomega Version 2.0 from the cd that came with my 100mb zip drive. Then I downloaded 2.1 from the Iomega site and installed over 2.0, I went into the extensions manager and disabled Zip250 ext., and then used Tech Tool 1.1.9 to rebuild my desktop. It works perfectly now. Hope this helps someone out.
