Hmmm. Not a solution (more like a hack) but since I have the latest Minix (1.2?) then can't I make a new file system by referencing your 3.5 drives as IBM AT 1.2Meg drives? (I don't have any docs with me now, but I think you reference AT drives as AT0 and AT1.) So... mkfs \dev\at1 720 will make a file system on a 720k disk. Is this reliable or dangerous? I am new to Minix, as you can well see ;) Then again, I was having disk driver problems when I was using 360k and they haven't gone away with 720k file systems... It seems my system fails test10 ('can't create file' errors) and every once in a while Minix locks up and goes away when I try to write to a disk. Other times, Minix and my drives just purr along. Hmmmm. Could this possible suggest that my Datavue Spark disk system is not quite IBM compatible??? _____________________________________________________________ | maroC ddoT | Todd Coram | | tcoram@udcvax.bitnet | tentib.xavcdu@maroct | | remmargorP | Programmer | | retneC retupmoC cimedacA CDU | UDC Academic Computer Center | |_____________________________________________________________| "Trust me, I know what I'm doing..."
