tmm5899,From long ago and far away (AKA when i used to use floppies a lot). I had this problem. It turned out to be a change in the BIOS that stated something to the effect"this device is permanently disabled".Scary huh! However turns out it wasn't and could be unpermentantly disabled. Wish i could tell you how i did it. Can only say it can be done.Others may come along to tell you how to do it. I feel quite confident that is what has happened to you. goodluck,truenorth
