As root edit the '/etc/fstab' file. I use this for everyone to have access for win7;
/dev/sdb2 /mnt/win7 ntfs-3g fmask=111,dmask=000 1 0
Please note the use of 'ntfs-3g' in the above line.
You might want to consider not using the fmask & dmask the way I have sampled since security will/can be an issue;
umask=nnn, dmask=nnn, fmask=nnnSets the user file creation mode mask, umask, the same for directories only, dmask and for files only, fmask. More detailed information about the fstab file can be found in the man page about Linux fstab
To understand fmask & dmask you can look at fstab
or 'man fstab'. Plus 'man mount' will provide useful information to understand options.
Hope this helps!
