Last week I finally was able to take my early 2011 iMac in to have my Seagate 1TB hard drive replaced for the recall.


Late 2010 model iMac

OS X 10.6.8

OWC Mercury Elite Pro 4TB x 4TB Hardware RAID


When I took it in the RAID 1 was working just fine. When I finally got the iMac back and booted everything up the RAID 1 was getting the dialog box that read "The disk you inserted was not readable by this computer."

I have tried going into disk utility to see if I can verify the disk and then saw it is coming up as two different volumes... Along with those two different volumes, I can not go to click verify as it is greyed out.

I contacted OWC and they said they have never heard of this and had two solutions, to try a software like diskwarrior, or if that didnt work I can take the drives out and try another external dock to see if it is the RAID hardware.


If anyone has any ideas as to what could help with this situation that would be great as I was under the impression (and told by a number of other people) that having a RAID 1 as my backup was good and should not need anything else. I just want to be able to get all the data off then I will rebuild it or send it into OWC.



iMac, Mac OS X (10.6.8)
