PROMISE SmartStor DS4600 Dead enclosure or dead drive(s)?
I have a SmartStor DS4600 4-bay RAID enclosure. It stopped working along with a burning smell that appeared to be coming from the unit's main board region. I ordered a replacement identical unit since this was needed ASAP and today plugged the drives into the new unit. I immediately smelled the same burning smell and quickly unplugged the unit. Next I took one of the drives (all 4 of them are Seagate NAS 4 TB drives, model ST4000VN000) and put it in a single drive external enclosure. That single drive enclosure immediately started smoking on the main board as well. Assuming I'd found the bad drive, I proceeded to try a known good hard drive with the single drive external enclosure (which worked) and then swapped in another of the 4 TB drives. That drive caused the enclosure main board to smoke as well (worse than the last one).
At this point my single drive enclosure appears to be dead, and I have two of the DS4600 units that may or may not be dead. I'm not sure how to proceed, but I'm quite afraid that I have one or more drives that are killing everything I put them in.
What should I do?
