I installed an Iomega Zip 100 (Atapi)on NT 4.0 machine and when booted showed up as "B" drive which is fine. Clicked on "Removable drive B" to copy files and got this msg: "B:\ is not accessible. Volume doesn't contain a recognised file system. Please make sure all file system drives are loaded." R-click on drive and "Format" but nothing happens. Thought I would run the Iomega CD and window where I choose which programmes to install has the top line greyed out "Drivers & something (must be installed)" I continue on and get error msg "shortcts.dll could not be found in specified path c:\winnt\system32." I searched and found that file and ran install again and got the same message only with "ioReady.dll" couldn't be found. What am I doing wrong. I'm not at all familiar with NT4. Any help will be appreciated................Nev
