Closed or Borrow: Spectrum +3 format disk to test a 3" drive.

As title, just after a non-corrupt disk to test a +3 disk drive. Happy to return it if nessasary or just to buy one. Just as long as it works. I am more than happy to pay for the favour if borrowing.

Thanks in advance.

I have one you can have for cost of postage which I previously bought from Dojodan.
