So I talked to Other World Computing and they sent me a replacement. I screwed up though, I went by the Thunderbolt id in softraid, but when i pulled a drive the id numbers changed, so I realized I didn’t know if I had the drive that was going offline. When I put the 4th drive back in (with no changes to the other drives) it took 2 days to re-sink the drives, with nary a thing to tell me how long it would take. I decided to back up my raid as quickly as I could. And when they came back they came back I wasn’t dropping a drive again, but now I was nervous.
So I upgraded my RAID from 2 tb drives to 12 tb and reformatted. I was quite surprised as when I formatted the 4 2 tb drives to make it RAID 5 and it took all of 30 seconds. This apposed to when I made the 6 TB raid, which just a couple of years ago took 4 days, which makes me wonder if there wasn’t an issue on one of the 2 TB drives to begin with. As the 36 RAID 5 took 30 seconds to create.
And I worry again because on the first night after formatting one if the drives went offline. Now it cane back with a restart, but it makes me worry that the housing was the issue all along, though OWC hasn’t responded to my further issues.
