    Disk /dev/sdb: 1500.3 GB, 1500301910016 bytes //未分区的硬盘，sdb 1500GB

    Disk /dev/sdb doesn't contain a valid partition table

    [root@NAT ~]# fdisk /dev/sdb
    Device contains neither a valid DOS partition table, nor Sun, SGI or OSF disklabel
    Building a new DOS disklabel. Changes will remain in memory only,
    until you decide to write them. After that, of course, the previous
    content won't be recoverable.

    The number of cylinders for this disk is set to 182401.
    There is nothing wrong with that, but this is larger than 1024,
    and could in certain setups cause problems with:
    1) software that runs at boot time (e.g., old versions of LILO)
    2) booting and partitioning software from other OSs
(e.g., DOS FDISK, OS/2 FDISK)
