I have a 3TB external hard drive that I plan to use for backups. I originally tried formatting with cfdisk, until I learned that only GPT supports 2TB+ partitions.
So I converted the drive to GPT and formatted the one partition I made to ext4, but I keep getting "Permission Denied" errors. Normally, udiskie is able to automount everything such that I don't see write errors such as this.
I feel like my lack of knowledge about GPT might be contributing to some oversight, but I'm not sure what might be wrong.
