My DUO (RND2150v2) is not booting anymore. It has the blinking blue light, and Raidar can't find it. It all started when one of the disks (#2) was reported as defective (WD10EADS). Re-syncing didn't help. Pulling one disk did, after that I could access the DUO with Frontview. I have tried several times to fix the problem by rebooting, resyncing, inserting one disk, and then the second disk etc and for some reason either disk 1 was reported as faulty while disk 2 seemed to be OK, or the other way around. The SMART log did not show any ATA errors, but I have never been able to get both disks working again.
I then decided to put in two brand new disks (ST31000524AS). At first I was able to get both drives up and running, and even write and read data to it. So I thought I had fixed the problem, and that it was a defective drive after all. In order to move the DUO to it's normal location I had to power it down with Frontview, but after that it failed to boot: blue light blinking for hours, no green lights. It is not even booting with one disk.
The fan is running at high speed, but once every five seconds or so, the speed drops, apparently when there is disk activity. I had it running for over 24 hours now, but no change. The fan speed is still fluctuating, as if the power supply is struggling to maintain the required voltage levels.
Does anyone have a suggestion on what to do next? I haven't tried a factory reset yet. Should I try that?
