Using "w" from fdisk "writes table to disk and exits"

At the CLI do "partprobe" after changing the partition layout in a disk.
"partprobe  is  a  program  that  informs  the  operating  system
kernel of partition table
changes, by requesting that the operating system re-read the partition table"

so "w" does something to the disk, partprobe tells the OS what was
done on the disk.
