lsg@edubuntu1404:~$ sudo sfdisk -d /dev/sdc > 500disk.txt

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！

做过lvm么？如果做过需要挂lv

不挂载那个硬盘的情况下,fsck检查下硬盘,看看能不能修复

blkid /dev/sdc1看看情况。
