问题:
      # mount –t ntfs /dev/sdb1 /mnt/usb
      mount: unknown filesystem type ‘ntfs’
      这是由于CentOS release 5.3(Final)上无法识别NTFS格式的分区。

解决办法:
      通过使用 ntfs-3g 来解决。
      打开ntfs-3g的下载点http://www.tuxera.com/community/ntfs-3g-download/ntfs-3g_ntfsprogs-2012.1.15.tgz ,下载到CentOS,执行以下命令安装:
      1) 编译安装 ntfs-3g:
            # ./configure
            # make
            # make install (或 sudo make install)
      2) 查看USB设备点
            # fdisk -l
            Disk /dev/sda: 154.7 GB, 154750418432 bytes
            255 heads, 63 sectors/track, 18814 cylinders
            Units = cylinders of 16065 * 512 = 8225280 bytes

            Device   Boot      Start         End       Blocks    Id  System
            /dev/sda1                    13      104391   83  Linux
            /dev/sda2              14       18814   151019032+  8e  Linux LVM

            Disk /dev/sdb: 500.1 GB, 500107861504 bytes
            255 heads, 62 sectors/track, 61781 cylinders
            Units = cylinders of 15810 * 512 = 8094720 bytes

            Device   Boot      Start         End        Blocks   Id  System
            /dev/sdb1                    61782   488384000+   HPFS/NTFS

      3) 挂载NTFS分区
            # mount –t ntfs-3g /dev/sdb1 /mnt/usb
