I purchaed the out of the box umbrel machine from The Bitcoin Machines. When I plug it in and go to http://umbrel.local to get it set up, i get an error message asking me to plug in an external hard drive of at least 1TB. Do I need to purchase an additional external hard drive to get this set up? If so, would it need to be the SSD one that they link to here?
Any help is appreciated, thanks!
