Install directions Richard Gaylord cautions that the directions for installing the VST Zip drive in a PowerBook may be a bit incomplete. In particular, after booting from the Zip Tools disk, make sure that the PowerBook's internal drive is selected as the startup device in the Startup Disk control panel (the directions do not mention this). Otherwise, when you run the Installer, the Zip extension may be placed in the Zip Tools disk (or get placed nowhere at all) rather than in your PowerBook's System Folder. If this happens, the PowerBook may not recognize a Zip disk when it is inserted into the module. VST Tech Support assisted Richard in solving this problem.
Security cable blocked? Richard and Andreas also write that, at least with a PowerBook 5300, when the Zip module is inserted, it blocks the ability to attach a security cable (such as the one from Kensington) because the Zip module protrudes in front preventing the full insertion of the cable.
