Ray, I would go with Roger's advice and get the slot repaired.

There are USB devices available that can replace floppy drives but they are complicated and you'll find that people won't be able to give you advice if you don't have a floppy drive.

I reckon it is theoretically possible for some brilliant engineer to hardwire an SD Card in to act as a hard drive but it would only be 1GB... and that leads me to another thought...

You said that if the card is in the KN7000 when you turn it on then it gets recognised. So, why take it out? Transferring files to your SD Card via floppy disk is probably easier than any other method. The only unavoidable reason I can think of for taking an SD Card out is to put SD Audio on it when you think about it.

This is assuming that you have a 1GB SD Card. I can't imagine someone needing more than 1GB.

Repair is the best option but if you can't get a repair then fill a 1GB Card with your favourites and then leave it in the slot and add to it via floppy. It is an idea anyway.

I have at long last found myself a reliable USB floppy drive for my computer, so I would now feel confident to recommend this method.

Best wishes,
Mike
