结果如下：

# partition table of /dev/sdc
unit: sectors
/dev/sdc1 : start= 63, size=976773105, Id=83
/dev/sdc2 : start= 0, size= 0, Id= 0
/dev/sdc3 : start= 0, size= 0, Id= 0
/dev/sdc4 : start= 0, size= 0, Id= 0
网上搜到一个办法：
http://gparted-forum.surf4.info/viewtopic.php?id=14172 要把分区表重新写回去，不敢写，也不知道如何改动然后写回。求助！
