Hi, I have had my EX2Ultra for a few years and had it running in RAID0 without any issues. I recently bought two new drives and configured in RAID1. When copying my files back to my NAS, I get a power loss error frequently. The unit reboots and is busy checking disks for a few minutes and then starts working again. I have had this happen 5 times in the last two hours, and I am getting worried that my unit is defective. The errors happened when plugged into a UPS and when plugged in straight to the wall outlet (no UPS), so i don’t think it is a power outlet issue.
I am on FW 2.31.204.
Any ideas as to what might be going on?
Error Message from log:
Power loss detected
Power loss detected on port 1.

That could be the reason. Checked my adapter and it’s a 18W, so for 2x6Tb that would be way to low. I also noticed it was running hot. Ordered a more powerful adapter (60W) which should arrive tomorrow and will test again… Will reply back to thread with updates.
UPDATE: after hooking up the unit with a 60W power adapter instead of the 18W adapter that came with it, it’s been operating error free. I am running 2x6TB in RAID1 and my UPS indicated it draws between ~20W-30W depending on the work load. No more power failures in the last 48 hrs.
