# fdisk /dev/xvdc
Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
Building a new DOS disklabel with disk identifier 0xf2bf5146.

After that, of course, the previous content won't be recoverable.

switch off the mode (command 'c') and change display units to
sectors (command 'u').
