Thomas, sorry I seem a bit confused. I wanted two things from this situation: consistancy- both machines have crossdos, as far as I can tell and only one can read pc disks. I would like to figure out how to make both of them do the same thing. I am limited by the fact that I haven't got a cross dos install in this pile of floppies scattered around the room, so set up is hard. Both machines appear to be set up the same, except for the os. Secondly- the thing that started this thread(for me anyway) was that I had tried in the past to format a disk on my amiga which turned out to be a pc formatted disk. My machine (tried) to format it as a pc disk using crossdos(apparently).When I bought a box of floppies at Staples they turned out to be all preformatted as pc disks and there was apparently no place to buy the old fashioned non-formatted DD disks. I know how to use the various ways to format an amiga disk (shell, menus etc) but each time I tried the machine would try to format it as a pc disk, and that format job didn't work out well because when it was done no machine could read the disk, including this Sony Vaio I am using as we speak. None of my machines (Amiga) can get to the internet in spite of a couple of years of trying, bringing in various hackers and geeks and dweebs and other euphamisms for knowlegeable people, including asking questions here... so the floppy is an important means of getting files from the web into my colection of amigas. Most of my amiga floppies have been used at least once, are ancient by floppy standards and several have back blocks etc. So I wanted to have a consistant supply of floppies that I could use as amiga formatted disks. Once I am able to create a networked group of machines this won't be such an issue, but for now sneakernet is my only way to move files around between the 5 amigas I own. Is that clear enough to figure out my problem? It's a stew of issues.... hope this clears things up, and hope someone can give me a solution. Thanks for your time!!
