Do you mean Mandriva? (Mandrake is obsolete)
Some distros automatically create mountpoints (directories) in either /mnt or /media.
If there is nothing already set up, you can do this (I'll assume that Windows is on /dev/hda1---substitute the correct device name--check with "fdisk -l" if necessary)
Code:
su ##to become root##
mkdir /mnt/windows
mount /dev/hda1 /mnt/windows
cd /mnt/windows
ls
You should now be looking at your Windows files
Assuming that this all works, you can edit /etc/fstab so that it happens automatically.
man mount
man fstab
for more details
