Moved from another list ... >>> Sometimes it can't even compile, I get a message saying "an error occured". >>> makes a click-whir-click-whir sound. Although I have a Zip drive on my G3, I rarely use it, preferring the size and speed of an external Jaz. I recently had a problem with a couple of Jaz cartridges, and when I finally gave up trying to get the data off, I gave up, and used Iomega Tools to re-initialise the disc. Only to be faced with an initialisation failure, even though the disc had hardly been used. Tried everything with the Iomega tools, and every single time the long reformat failed. These are expensive cartridges !! So I pulled out an old copy of "MicroNet Utility v7.2.7", and tried to initialise and reformat the Jaz cartridge. Worked first time on both discs and mounted them. Then I went back to the Iomega tools, and it reformatted the cartridges perfectly. And they have worked OK since. I guess the moral is that the Iomega tools aren't fully trustworthy. Now I'm not suggesting that it's in their interest to have the reformat fail so that you have to buy a new cartridge, but ... Phil.
