Assuming your Windows partition is NTFS (most probably a reasonable assumption):
First, find out what label your Windows partition has gotten in CentOS. As root, run
fdisk -l | grep NTFS
The left-most column is the partition label that you need later (assumed to be
/dev/sda1 below - just change accordingly). The right-most column is the file system on the partition, and with
grep we only pick those partitions that are NTFS.
Then, for CentOS 6, condensed from http://wiki.centos.org/TipsAndTricks/NTFS:
For CentOS-6, the EPEL repository is carrying NTFS packages. To install, after enabling the repo per the Repositories page:
yum install ntfs-3g
or if you prefer to leave EPEL disabled by default
yum --enablerepo epel install ntfs-3g
You may also want to
yum install ntfsprogs ntfsprogs-gnomevfs
for additional functionality.
Mounting an NTFS filesystem
Suppose your ntfs filesystem is
/dev/sda1 and you are going to mount it on
/mymnt/win, do the following.
First, create a mount point.
/etc/fstab as follows. To mount read-only:
/dev/sda1 /mymnt/win ntfs-3g ro,umask=0222,defaults 0 0
To mount read-write:
/dev/sda1 /mymnt/win ntfs-3g rw,umask=0000,defaults 0 0
You can now mount it by running:
