Terrence J. Gold –
These work. You need to write them first with something before it will read. Otherwise whatever tool you are using to write will come up with errors. So just write whatever dummy data you want first like hid26 fac 1 CN1 so all to prep then you can write anytime you want. Until you do will seem like they don’t work if you read or decode them first. Also, make sure you set modulation to the same when preparing and writing to avoid issues. But they work, tested them pretty well in my lab.
