mount_msdosfs: /dev/cf0s1: : Operation not supported by device and thought I'd fix it to be: mount_msdosfs: /dev/cf0s1: Operation not supported by device Not sure why errmsg isn't getting filled in, or why this error is even happening at all... (fsck_msdosfs is clean, and I can mount this same CF elsewhere).
