I'm running Windows '98 SE, so i have no other option than use external programs, to protect my hard drive files i use "Hide Folders", it's a free utility that let you..... hide folders, last free version let you hide just 2 folders, but payed version let you hide 16 if 2 is not enouhg for you.

I use an encription program before backup files to Cd's, any one can do this.
I also use Linux, there is no problem, if you have 2 linux installations, you will see that it doesn't matter if you log as administrator, you can't see the protected files of the another installation, delete them, backup them, or anything else, oviouslly linux must be configured correctly to do it.
Hope this help.
