+Device contains neither a valid DOS partition table, nor Sun, SGI, OSF or GPT disklabel
+Building a new DOS disklabel. Changes will remain in memory only,

+The number of cylinders for this disk is set to 13054.
+There is nothing wrong with that, but this is larger than 1024,
+and could in certain setups cause problems with:
+) software that runs at boot time (e.g., old versions of LILO)
+) booting and partitioning software from other OSs
