A tool called Raidreconf can do what you want. I have never used it. I don't know how much risk there is in data loss. I would backup my data first! Find it, read about it, and understand it. Maybe someone else can comment on the risks?

However, 3 of 6 drives have proven to be faulty and have been RMA'd. I've successfully built the array using the remaining 3 x 250GB drives (details below) Now, when I get the other three disks back, how do I add them to this array and increase the size of the array? Is this possible? Thanks, R.
