Thanks for any help and I apologize in advance for my ignorance. I am running Disk Director Suite on XP Pro-SP2. I have only one OS. I did not install OS Selector. I have 3 hard drives and I wanted to make two partitions from one of the physical drives, which I managed to do. When I look at the graphical representation of the drives and partitions, 3 of them are flagged in red. I believe that means that they are "Active" (whatever that means). Is it OK to have 3 "Active" partitions? Should just the C:\ drive (the boot drive) be active? Is there a way to change a partition from a red flag to a green? Thanks very much for any help.
