Hi, I had intended to build a RAID5 array using 6 x 250GB drives. 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.
