Hello, welcome to the forum.

If no one's got one knocking about, I'd be fairly confident that CJE will:

Fungus merrily grows on floppy discs, there's enough moisture in the air. Food-source-wise they use all sorts of things - organic compounds in some plastics would certainly fuel them...

Check ebay sold prices and decide what you'd take for it?

They've gone anywhere from £30 to £70. e.g. https://www.ebay.co.uk/itm/Acorn-Electr ... 2160796722

There is a direct access mode that gives you direct access to the sd card blocks, but you'll need to implement a FAT library on the host. Then there's the "choose an indexed image", which is what this really is. There's nothing to stop you implementing something to give direct accessas you describe ...

Previously formatted on a pc can cause problems, and using an HD disk definitely can cause problems.

In this instance it could we...
