I have only just received my new DS1812+ on 01/06/2012 and it has only been in use/testing for about 3 days.
I had left it running over night just sitting not doing anything after creating the new volume. In the morning I went to connect to it via the Synology Assistant and it started to make a clicking sound and I was unable to connect to the device. After about 10 minutes I manually powered down the device and rebooted. After reboot there was no issue, the clicking sound had stopped and I was able to connect to the DS1815+ and my volume was fine.
However, on the second morning (today) I have experienced the same issue. This time after power down and before rebooting I removed HDD 1. The Clicking stopped, I connected to the DS1815+ and had a notification saying volume1 was degraded. I powered down and swapped the HDD1 i had removed with HDD2 and rebooted. This time no clicking sound but I had a notification saying volume1 was degraded because HDD2, which was organically in bay1, had crashed (System Partition failed).
I am in the process if repairing the Volume with this "failed" HDD (Checking parity consistency).
Is this a normal HDD failure requiring a replacement HDD or has this something to do with the "blue blink of death"? or both?
I have 2x 1TB Samsung HD103UJ and 2x 1TB Samsung HD103SI (one of which crashed and is repairing at the moment). I am running DSM V4.0-2216.
I have sent the above in an email to blueLED@synology.com
along with my serial number. Has anyone experienced this issue or anything similar?
