ubuntu下修复U盘并格式化

前一段时间U盘分区表被搞坏了,在Win7下没有太好的命令来修复,量产工具也是各种不给力,最后还是在ubuntu下搞定的。这里笔记下使用的工具吧:

查看和修改分区fdisk:

可以使用fdiks查看和修改分区,这里作者就是通过o命令来重置的分区表。

cstriker1407@cstriker1407-x64:~$ sudo fdisk -l #查看当前分区

cstriker1407@cstriker1407-x64:~$ sudo fdisk /dev/sdb1 #选中U盘分区

Welcome to fdisk (util-linux 2.25.2).
Changes will remain in memory only, until you decide to write them.
Be careful before using the write command.


命令(输入 m 获取帮助): m #使用m命令查看

Help:

  DOS (MBR)
   a   toggle a bootable flag
   b   edit nested BSD disklabel
   c   toggle the dos compatibility flag

  Generic
   d   delete a partition  #删除分区
   l   list known partition types #查看支持的分区类型
   n   add a new partition  #新建一个分区
   p   print the partition table #打印当前分区表
   t   change a partition type  #更改分区类型
   v   verify the partition table #校验分区表

  Misc
   m   print this menu
   u   change display/entry units
   x   extra functionality (experts only)

  Save & Exit
   w   write table to disk and exit #保存分区并退出
   q   quit without saving changes

  Create a new label
   g   create a new empty GPT partition table
   G   create a new empty SGI (IRIX) partition table
   o   create a new empty DOS partition table
   s   create a new empty Sun partition table

格式为NTFS:

cstriker1407@cstriker1407-x64:~$ sudo mkfs.ntfs -f /dev/sdb1 -L MyUSB  #使用mkfs.ntfs对U盘进行格式化
cstriker1407@cstriker1407-x64:~$ sudo mkfs -t ntfs /dev/sdb1  #使用mkfs对U盘进行格式化

cstriker1407@cstriker1407-x64:~$ mkfs  #mkfs使用帮助
用法:
 mkfs [options] [-t <type>] [fs-options] <device> [<size>]

选项:
 -t, --type=<type>  filesystem type; when unspecified, ext2 is used
     fs-options     parameters for the real filesystem builder
     <device>       path to the device to be used
     <size>         number of blocks to be used on the device
 -V, --verbose      explain what is being done;
                      specifying -V more than once will cause a dry-run
 -V, --version      display version information and exit;
                      -V as --version must be the only option
 -h, --help         display this help text and exit

For more information see mkfs(8).
