Cab you somewhat more clear about what parts of your story are about a USB external hard disk and what parts are about a USB stick?

Are both defective now, or only one?
- If only one doesn''t work now only tell about what you did with that one that and leave out all about the other.
- If both don't work tell about both, but in separate paragraphs, both what you did with it and what happens if you plug it in.
