I guess I should have selected “Everyone” when mounting because I can’t copy items into the drive. And I keep getting this error when I try to unmount the drive and delete the partition:
You missed a step in my instructions
“You will need root or sudo access for all of this:”
The easy way to get root access in your case is:
sudo su - at the command line (you will be prompted for your user password)
then umount (filesystem_of_interest) … make certain that you do NOT have any sessions operating in the filesystem or you will not be allowed to unmount the drive.
IF you also want to setup root with a password, while you are currently in the sudo session:
passwd root
you will be prompted for root’s new password …
This worked for me! Afterwards, I used wipefs --all --force /dev/sdX (insert your specific drive) to wipe the drives. Restarted, and the drives were now able to be remounted. I redid the steps in the guide I linked in my original post, but this time I selected “Everyone” instead of “Root”, and my drives are mounted and seem to be working as intended; I’m able to copy files over and read and write.
I was able to unmount the drive and delete the partitions based on the previous comment.
