My A3000 internal floppy drive is not recognized, even though it constantly clicks, waiting for a disk to be inserted. At the moment, I have an external floppy hooked up and that one is recognized. Strange stuff.
Strange, not at all. I have seen many drives exhibit this behaviour, when they are dirty, or out of alignment.
is it chinnon fb354? if so then you can try sending it to us, and we can attempt repair (if repair doesn't work we can ship another drive to use).
