Mount windows partition in linux

First find out partition detail,

#fdisk -l

#mkdir /win

#mount -t msdos /dev/sda1 /win .....(If partition is FAT32)

-or-

#mount -t ntfs /dev/sda1 /win .....(If partition is NTFS)

#cd /win

Note: If your are using RHEL 3,4,5 then NTFS mounting will not be Supported. For that you need to complile a new kernel.
