How to lock a partition on Windows XP Home run PC?

[jammerules]

Well, the title says it all! I am running a XP Home SP2, P4 3 Gig Hz machine and I have like 4 partitions each of about 40 gig space. I made these partitions using Partition Magic 8 and also have Acronis Disk Director that I once read will be useful to lock a partition. When I checked the Acronis application I could not find any option that helps me lock a drive. The reason behind is simple - I dont want to delete the partition accidentally. Do any of you guys know how to do it right with Acronis Disk Director?
