重做系统后，ds存储挂载不上了
之前用mount -t ntfs-3g -o iocharset=cp936 /dev/sdb1 /cpg 可以的，重装了rhel6.5 64位后，现在挂载报错

Error reading bootsector: Input/output error
Failed to mount '/dev/sdd': Input/output error
NTFS is either inconsistent, or there is a hardware fault, or it's a
SoftRAID/FakeRAID hardware. In the first case run chkdsk /f on Windows
then reboot into Windows twice. The usage of the /f parameter is very
important! If the device is a SoftRAID/FakeRAID then first activate
it and mount a different device under the /dev/mapper/ directory, (e.g.
/dev/mapper/nvidia_eahaabcc1). Please see the 'dmraid' documentation
for more details.

NTFS signature is missing.
Failed to mount '/dev/mapper/mpathc': Invalid argument
The device '/dev/mapper/mpathc' doesn't seem to have a valid NTFS.
Maybe the wrong device is used? Or the whole disk instead of a
partition (e.g. /dev/sda, not /dev/sda1)? Or the other way around?

留意到这个错误提示吗？ 是否按照错误提示操作处理来看看？ 我这里只是用fdisk 查看下，不是要重新分区

fdisk不行的 原主库上看：
