    Question Raid migration
    Just trying to find out what the best way to either migrate or create a RAID 5 Array with my existing J+ and 3 other drives in my Mac Pro? I just added 3 new drives to the unit and want to have it all as a collective RAID 5 Array.

    There is only one way to do it right:
    1) Make a full backup of all your data on the drives hat you are going to reconfigure.
    2) Reconfigure your drives in the RAID config you want.
    3) Restore your data from the backup taken in step 1.

    I know there are tools that can change a RAID config on the fly, but I would not trust them without making a full backup first.

    A computer lets you make more mistakes faster than any invention in human history - with the possible exceptions of handguns and tequila.
    The bitterness of poor quality remains long after the sweetness of low price is forgotten.
