Marcelus, I don't think you can "convert" a 1.4mb floppy into a 800k. There are some media differences. The heads of a 800k floppy drive are not strong enough to write on a 1.4mb disk. After some time, the data you stored on the floppy disk will just vanish. It happened to me once, and I heard several people saying the same thing. Just buy a 720k floppy disk for PCs. It will format at 800k on the Mac. It's the same disk. Hope this helps, Lucas >Hi, > > >Does anyone of you know how to "convert" a 1.4MB floppy into a 800K one? > > > > >-- >Marcelus. ><http://magiozal.blogspot.com/>
