在 Ubuntu 上挂载新的硬盘

  1. 找到新添加的硬盘

    $ sudo fdisk -l

    Disk /dev/sda: 31.5 GB, 31457280000 bytes
    4 heads, 32 sectors/track, 480000 cylinders, total 61440000 sectors

    Units = sectors of 1 * 512 = 512 bytes

    Sector size (logical/physical): 512 bytes / 512 bytes
    I/O size (minimum/optimal): 512 bytes / 512 bytes
    Disk identifier: 0x0004fdcb

    Device Boot      Start         End      Blocks   Id  System

    /dev/sda1 * 2048 61439999 30718976 83 Linux

    Disk /dev/sdb: 107.4 GB, 107374182400 bytes
    255 heads, 63 sectors/track, 13054 cylinders, total 209715200 sectors
    Units = sectors of 1 * 512 = 512 bytes
    Sector size (logical/physical): 512 bytes / 512 bytes
    I/O size (minimum/optimal): 512 bytes / 512 bytes
    Disk identifier: 0x00000000

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

  2. 分区

    $ sudo fdisk /dev/sdb

    选择：n 添加新分区

    选择：p 选择添加主分区

    选择：1 选择主分区编号

    选择：w 保存退出

  3. 格式化

    $ sudo mkfs -t ext3 /dev/sdb1

    用ext3格式对/dev/sdb1 进行格式化

  4. 挂载

    $ sudo mount /dev/sdb1 /dir

    将分区挂载在/dir下

    再设置开机自动挂载

    编辑/etc/fstab添加一行

    /dev/sdc1 /dir ext3 defaults, 0 1

  5. 确认

    最后查看一下是否挂载正确

    $ df -h

Filesystem      Size  Used Avail Use% Mounted on
/dev/sda1        29G  5.9G   22G  22% /

udev            827M  8.0K  827M   1% /dev

tmpfs           168M  392K  168M   1% /run

/dev/sdb1        69G   52M   66G   1% /mnt

**/dev/sdc1        99G   60M   94G   1% /dir**
