Help cange permissions of mounted devices

[nmset]

As far as I remember, Mandriva 2008 doesn't has full support of ntfs-3g module (I may be wrong). You are readily advised to do a full install of 2010.0 instead. You'll have read/write support for your NTFS partitions only with the ntfs-3g module, which is not in your fstab.

[root@localhost ~]# cat /etc/fstab
/dev/hdc9 / ext3 relatime 1 1
/dev/cdrom /media/cdrom auto umask=0022,users,iocharset=utf8,noauto,ro,exec 0 0
/dev/hdc5 /mnt/win_d ntfs defaults,umask=0 0 0
/dev/hdc6 /mnt/win_e ntfs defaults,umask=0 0 0
/dev/hdc7 /mnt/win_f ntfs defaults,umask=0 0 0
/dev/hdc1 /mnt/windows_c ntfs defaults,umask=0 0 0
none /proc proc defaults 0 0
/dev/hdc8 swap swap defaults 0 0

Didn't you edit /etc/fstab file as I suggested earlier?
