I've recently bought the DNS-321 and set it up with 2 1TB drives RAID 1. After 2 days, the left hard drive turns a purple color (not amber like the documentation says) and I get an email notification telling me that my left hard drive has failed.
OK, no sweat... it was a new drive but things happen. I replace the left hard drive with another new drive, re-synch and all that good stuff. 2 more days later, the left drive fails again.
I am suspicious. Anyone else have this problem. Seems a little bit of a coincidence to me. Before I go thru the hassle of replacing this drive again, I want to try to find out if there's something wrong with the NAS. Of course, D-Link support ignores me emails.
