unfortunately my windows partition also dont known in centos and like my external HDD dont recognize as a partition.
In disk utility its known as a unknown partition.
what can I do?
I also run the fdisk -l and got this

Disk /dev/sda: 250.1 GB, 250058268160 bytes
255 heads, 63 sectors/track, 30401 cylinders
Units = cylinders of 16065 * 512 = 8225280 bytes
Sector size (logical/physical): 512 bytes / 512 bytes
I/O size (minimum/optimal): 512 bytes / 512 bytes
Disk identifier: 0xc96b2927

Device----Boot---Start-----End------Blocks-------Id----System
/dev/sda1-----------1------5737------46080000---83----Linux
/dev/sda2----------5737----5992-----2048000 ----82----Linux swap / Solaris
Partition 2 does not end on cylinder boundary.
/dev/sda3----*-----5992-----6037-----358400--- 7---- HPFS/NTFS
/dev/sda4----------6037------9817----30361600---7---- HPFS/NTFS

I also run the grub-install /dev/sda3 and grub-install /dev/sda4 on the rescue shell.
