Very frustrating tech support (15682575)

It's an Ultra 4 Plus, model RNDP400U.
The drives are 4 Seagate ST2000DL003.

When I bought the system in late March, I purchased 5 identical drives. When I first set up the system, I brought it up with the first 4, let it build the volumes, etc. (default XRAID), and then swapped one of the drives out with the spare to make sure ALL of the drives were functional. Everything was fine for over a month, then I got a drive failure (status DEAD) on FrontView. I can't remember what else occurred (since I can't see any of my case notes... GRRRR), but tech support decided it was a hardware issue and sent me a new chassis. In retrospect, the failure happened not too long after I set the "drive spin down" option in the power settings... I'm really wondering if that is what started this whole debacle. So I got the new chassis, swapped out the drives, and very shortly after that I got a message in FrontView that TWO drives (1 and 4) were DEAD. But all of the data was still accessible, and everything was green in RAIDar, and there were no drive lights flashing on the chassis. That's when I opened this ticket. A few days later, RAIDar and the chassis indicated that drive 4 had truly failed. So I put in my spare, fully tested drive. The system is now spamming me with emails every few minutes saying "Data volume will be rebuilt with disk 4." The front panel says Drive 4 checked, but FrontView says it's still DEAD. I think something got corrupted in my config / metadata for the volume during the original failure, and the problem simply got moved to the second chassis. The system would not execute RAID scrubbing either, because it thinks it's degraded.

The system has been in "tech support" mode waiting for L3 to telnet into it for the last several days, so I'm not sure exactly what the status of the system is now, and whether or not the data still seems to be present. Haven't been able to do any backups...
