Lines: 15 My experience with writing 360K disks on 1.2M drives tells me don't do it. A couple years ago, a friend of mine and I bought ATT 6300+ machines from the same store. Today, with his 1.2M drive, he regularly writes 360K disks and they work in 360K drives all over the place. When I try to do the same thing, nobody can read the disks. My guess is that his drive happens to position the head precisely (much beyond tolerances) where a 360K can read it while mine doesn't. Since I have had experience with about 20 1.2M drives and his is the only one that reliably writes 360K disks, I chalk it up to him getting lucky. Personally, I wouldn't dream of putting anything important on a 360K disk with a 1.2M drive and expecting a 360K drive to read it (a 1.2M drive usually will, but that is another story).
