You can mess up the partition table on disk, and the kernel won't be
aware of the changes until the system is rebooted.

As this is a new disk, it sounds like you don't have any data that needs
to be preserved on this disk. I think you would do best by using fdisk
or parted to completely remove any existing partitions and start over,
rather than trying to preserve what is there. Reboot after creating any
new partitions before trying to use them.
