I thought the net might be interested in the answer. I was virus infected! The virus was one of those boot-sector executable things. It just installs itself in the operating system so that any time the media-change call is made the virus makes sure that the disk is infected. Nothing else will happen until some unknown trigger comes along in a new infection and then the old virus will trigger the new one (or vice versa). This virus just happened to do something to the disk that caused the IBM to be unable to find any valid files but the Atari still thought that everything was OK. All of the common virus dectector/ killer programs that I found found this thing and then could remove it. Damn near every disk I had had been infected by the time I found out what was going on. Every thing works just like it should, now. Cheers, Terry -- T. Terrell Banks uucp: { 'insert a backbone name here' }!gatech!prism!iadt3tb Georgia Insitute of Technology - I.S.A.
