Error: "failed to preserve ownership" when trying to move files to a FAT32 partition on OpenBSD

I'm following a tutorial on how to install firmware on OpenBSD. The tutorial has me creating a new msdos file system on the usb with: newfs_msdos -F 32 /dev/rsd2c then to take usb to a system with an internet connection, then move the firmware tarball into the USB. I have never moved data to a msdos fs via the command line before. The tutorial shows him using dolphin on a manajaro install, however I do not have any systems with gui's installed. How can I move the tarball to the usb drive? I've tried mounting it them moving to the mounted directory but it does not work. Stating failed to preserve ownership for '/mnt2/iwn-firmwae.tgz': Operation not permitted Here's a link to the tutorial: https://www.youtube.com/watch?v=kUrUq2qfWiY
