So, mp1.1, had a raid10 setup (software). started to act weird so I CCC:d the data to new disks and decided to break the 4 disk raid10. Partially succeeded, but the last two disks won't reformat, no matter what. they don't show up on the desktop, and under diskutil they show up as raid slice A / "drive has a hardware problem and cannot be repaired" or when trying to erase : "Volume erase failed with the error : Disk object invalid or unable to serialize". This happens if I throw in both drives at the same time or separately. Any go around, via terminal perhaps? I have 2 disks now that I can't format..
