Hi A coupla days ago I asked about formatting a zip drive so that it could be read by a mac, nt, and linux. I've finally managed to get the thing working correctly. Thanks to Kevin Bullock, Troy Johnson and Andy Zbikowski (sorry about the spelling, but hey, I tried). All pointed me in the right direction as far as where MY error was (seems it's always that way :( ). I tried formatting and partitioning so many ways on so many different devices I couldn't remember what I'd done or why. Nothing seemed to make sense, which usually means I've done something pretty stupid AGAIN. The answer was to simply to either format it in NT as fat or partition it in linux as fat and then mkfs it as vfat (seems I must've tried that a few times, but who knows). Anyway, it works just fine now. Of course, the mac still has a problem with the CR/LF thing, but I don't think I'm going to worry about that as I don't really know of a way to deal with it. To answer the leftover questions, the disk was not being served out. When mounted, the device looks like a regular disk drive, though I've changed that to the zip.png file. Most of my machines are dual boots with a zip drive on them, and we also have macs around, so this will make a convenient way to get medium sized files between them. I hate it when I stumble over my own 2 feet! Thanks for the help. Ed Hoeffner 1-271 BSBE 312 Church St. SE Mpls, MN 55455 hoeffner at dcmir.med.umn.edu 612-625-2115 612-625-2163 fax
