Changing RAID-0 block size without starting over?

    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.

    Unfortunately, No.

    The disks will have to be initialized again with the new settings, which will wipe out the existing data stored on them.

    I figured as much. Thanks for confirming.
