So today my Gen 1 did something odd. I had replaced a 1.5TB drive with a 2TB drive a few days ago, and it finished rebuilding yesterday. I let it sit for a while, then started to copy 600G of ripped DVDs onto it from another external USB drive.
During this process, it started another rebuild, which completed just now. All I can assume is that I have a drive that flipped out and disappeared for a while, and then came back. I have NO WAY of finding out which drive that was so I can pro-actively replace it, so now I have to just wait for it to fail permanently. This is not acceptable, the Drobo knows which drive did this, so it should give me a way to see which one is “suspect” and that I should keep an eye on.
[By the way, I now have four 2TB drives in it, and about 550G free, which triggered it to set a yellow light on one of the drives with a “replace the indicated drive with one of higher capacity” message. If only that were possible on a Gen 1. It’s not even possible on the Gen 2 I have sat in a box waiting patiently for the promised firmware update…]
