Simple way to generate a failed result?

[DavidAValentine]

I have a quick (and hopefully) simple question. I'm looking to create a little video that shows how to use this tool. I'd love to show how a faulty usb key would look (as well as a successful one).

I've tried to overwrite the 1.h2w file during the write process, (when it's writing larger .h2w files) but that causes the write process to stall near the end, and it never gets to the read process. I've tried all manner of things to trick it, but honestly I'm out of gas. Any simple suggestions?

Thanks so much, Dave
