How to prevent limited user from accessing 2nd drive?

[alegator]

Hello, I'm currently running a WinXP Pro SP3 PC as Administrator with full rights&privileges and just added a 2nd limited user that will be using this same PC. The PC has a main drive (the C drive) and a 2nd internal hard drive. I want to prevent the limited user from accessing/seeing the 2nd drive. I understand that the way to do this is by logging in as administrator, right click the 2nd drive icon in My Computer, go to "Sharing and Security...", and enabling the "Make this folder private" box. However, when I do this I see the "Make this folder private" box greyed out (inactive). How can I fix this? Mabe the associated Service that enables this function is disabled? If so, which Service adds this funcionality? Thanks.

If you create a folder on the drive you should be able to check that box. Blocking access to the root of the drive might be tricky and probably can't be done from the shell. There's a registry setting for this but I'd have to Google for it. Any reason why you can't go the folder route instead of the entire drive? The drive itself will still be visible to another user even with that flag active.

Hello alegator.

You could encrypt the files and folders you want to be kept private with this.

Thanks everyone for their replies. I found this free Microsoft program very cool for controlling all user permissions and settings. It's very user friendly:
