apple raid missing disk
Hello,
i have apple raid concatenated JBOD 4 disks storage, without redundancy, everything was working normal when the power goes down and did not come back to mount the raid unit, the hard disks are working perfectly without problems, it is only logical problem of the raid partition that has lost a slice and does not mount more, I have personal files like photos that I do not have backup, who can help me giving tips on how to recover and ride this raid again I will be very grateful.
