I have a Windows 2008 Standard server. It currently has 3x 1TB drives in Software RAID 5 (as per the Disk Management Console).
I need to add another 2x 1TB drives.
Is there any way to add these two disks into the existing RAID 5 array without any data loss, or without having to back everything up (We don't have that much extra free storage avaliable on short notice)?

It would appear that the short answer is "No" - a Windows RAID-5 array cannot be expanded (safely) once it has been made. So make sure you get enough headroom in it in the first place, or buy a proper RAID controller that supports online expansion!
