External Storage and Data Disk Move, no suitable storage found error

I’m running into the same issue as this person.

I followed the guides here Common tasks - Operating System - Home Assistant and made sure to insert a drive that has no partitions on it but still getting the error message (Home Assistant is running inside a mini PC on a 180gb SSD, the external drive I’m plugging in is 240gb SSD via USB 3.0)

Is there something I’m missing or should I wait some hours like he did and it’ll show up? The guide doesn’t say to reboot or anything, I tried that as well just to be safe. Just curious if there’s anything else I could be missing
