fdisk /dev/sdb # enter operation mode for partitions Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel Building a new DOS disklabel with disk identifier 0xd70e2fb8. Changes will remain in memory only, until you decide to write them. After that, of course, the previous content won't be recoverable.
