Question restricting user access to ntfs partition


Despite having signed up for a good long while ago, I've only just managed to prise myself away from windows, and so I'm guessing that the newbie area is the correct place for this question.

Apologies if I get any terminology wrong.

Here goes:

1. I have 2 hard disks: one that contains only an NTFS partition, and another that contains both an NTFS partition and a Fedora 9 (x64) partition

2. At present, I can access all partitions from both my root and regular user accounts

Is there a way to restrict regular user access to the NTFS partitions whilst maintaining accessibility from the root account?

Ideally, I would like to restrict access to all NTFS folders except one (itunes), so that I could effectively share the contents between the two operating systems without providing unnecessary access to any other files or folders.

So, basically:

root = access to everything
normal user = access only to linux partition and a single folder on an NTFS partition

Any help would be greatly appreciated, as this issue is driving me mental at present

Thanks in advance.

edit your fstab file and add a line/lines for your windows drive
/dev/sda1  /mnt/windows      ntfs-3g  defaults    0 0 umask 022
this should change the permission to 755 /mnt/windows

755 permission is user= read, write, execute; group=read, execute; other=read execute. I think this person wants 700 permissions, denying access to the directory. I would try (as root)
chmod 700 /dev/sda
Doing this as root makes the user 7, everyone else 0 so no one can access the file. You may wish to substitute /dev/sda with /dev/(drive name.)You can find this with-
cd /dev
The drive name should be there.

Many thanks for your replies.

I used the chmod command to restrict access to the entire drive, and this seems to work just fine.

Is it now possible to give normal users access to only a single folder on this same drive (my 'iTunes' folder, for example), or am I looking at this in entirely the wrong way?

I'd like the normal user account to be have access to a particular folder, but not to the rest of the drive.
