Hi guys, Is there any way to change the Block size of my RAID stripe to a lower value without starting over? The option in disk utility is greyed out. I was experimenting and set it to 128k and I find that it has slowed down my machine a little compared to the default 32k. I'm mostly only using it for LightRoom 3 and CS5 so 64 or 32 would probably work best in my case. Unfortunately my OSX disc is on loan to a friend so starting over is not an option at the moment! Thanks in advance.
