Not just that, but the aerodynamics have been screwed up. The heads will no longer "float" on an air-cushion; I believe the gap is the traditional human hair width, if that. Trivia: there is a small NiCd battery in the RK-05 drive which has to be replaced every so often; its sole job is to drag those heads back in the event of a power failure, whether it was writing at the time or not. -- Dave Horsfall DTM (VK2KFU) "Bliss is a MacBook with a FreeBSD server." http://www.horsfall.org/spam.html (and check the home page whilst you're there)
