I previously had 4 3TB harddrives in a Raid 5 on my ASRock Z87 mb but I had an extra 3TB hard drive so I decided to add it to the array. I installed it and expanded the Raid inside the Intel Rapid Storage Technology application and after a few days of migrating it seemed to be all good. Intel RST shows the array as having 5 drives and reports the size I'd expect, but the previous size of the 4-disk array continues to be displayed inside Windows Explorer (I'm on Windows 7).
Any ideas how to get Windows explorer to display the new, actual size of the array? Did I miss a step?
