It might be an alignment problem, but sometimes my old drives read old disks better than my new drives. This should be no problem if you have a friend with an external 400K drive. There is no way that I know of to make an 800K MFS disk. I wanted this to happen pretty badly for a certain application, but NOOOOO. If there is a way, please post it. I'm willing to be proven wrong!....bc
