December 31, 2025Dec 31 I have spent an untold amount of time in UnRAID trying to fix things for over three weeks now. Docker never works, and it took almost 12 hours to get a Ubuntu Server VM working, and now after all of that I finally purchased a new Samsung FIT Plus to replace the USB drive that was never meant to be used permanently. I used this Sandisk Extreme just to test Unraid and no matter what guide I use, including the Unraid guides this thing refuses to let me replace the USB drive without trying to force me to purchase a license before my Trial is up. How do I replace the USB flash drive with the proper one I purchased just for this Server?RegardsRod

I continuously get a error message saying "key replacement failed". It couldn't be any easier to understand the instructions but it does NOT work, period. I also tried the manual method multiple times to no avail as well.

I went to a different machine, created the flash drive again using both official methods and still it keeps telling me Key Replacement Failed. So I broke down and contacted them. Thank you!Best Regards,Rod

It clearly tells you how to replace a USB drive, and that's what I followed. So in order to use this nice new tiny USB drive I got specifically for Unraid I have to wait until my Trial period is over and then purchase a license? Just wow, that reminds me of Microsoft to the T. I'm in my trial period so you would think they would make this easy and less stressful on potential customers.

Nothing stops you getting a paid for licence for the new flash drive immediately, and if you do that you can copy the ‘config’ from the old drive to bring across the setup from that trial. The alternative is you start a new trial for the new drive, but then you have to set some things up again.
