A. If you have a piece of hardware that does not have a driver with NT you should check in two places, the maker of the hardware, i.e. for the Iomega Ditto goto www.iomega.com . If there is nothing there you should try the Microsoft site as they make the drivers for some hardware, for example the HP NT 4.0 drivers are made by Microsoft. If you cannot find the driver in either of these places then e-mail the technical support of the hardware maker, asking them for the driver, in some cases the driver is not on the web site, but they will e-mail it to you (makes a lot of sense :-))
For Iomega drivers can be downloaded from 1-800-998-0037.
