I want to pass down my older computer to my little brother but keep part of the hard drive as one of my places to save backups. I have the HDD partitioned into 3 partitions, and all my stuff is on just one of those partitions. So ideally, I would like to make it so that his user account cannot at all access that partition. Just to block it off completely. However, on my account I would still be able to access it. If it can't be done with an entire partition, then it would be okay also to restrict or block individual folders.
How do I accomplish either of this? I've tried searching the net but I can't find it/figure it out.
The machine is running WinXP Pro 32bit.
