Rice's answer in "more common" terms ... attempting to use a HD disk on a drive not designed for it is akin to an attempt to use "metal particle" audio cassettes on a drive not designed for them. In the audio cassette world, you have "metal particle", chromium dioxide (CrO2) Ferrichrome (FeCr2), and the ol' rusty iron on plastic run-of-the-mill ferric oxide formulations. Each requires special treatment in regards to bias, head current, etc. for optimum performance. Thad Floryan [ thad@cup.portal.com (OR) ..!sun!portal!cup.portal.com!thad ]
