Hi,
Yes, it's connected via USB3. No eSATA involved. The enclosure itself is an Orico 9558-U3. It's basically a 5-bay USB3 3.5" enclosure. As for connections, it's actually connected to a Mid-2012 15" MBP. This device is then passed-through via Parallels Desktop 12 to a Windows 10 VM.
I'll try my best to describe the 'issue'. My main concern is that whenever I tried to pull a disk (be it dead or otherwise), the entire enclosure goes offline and then re-connects again. My first question will then be is this expected behaviour? The moment this happens, DP will 'think' that a disk has gone missing and subsequently came back online. This triggers the lengthy 'measuring' process.
I observed this behaviour on other USB connected enclosures as well. I have also the very reliable Probox 4 Bay eSATA & USB2/3 Enclosure. These are connected to an Intel H67 based board via ASMedia USB3 controllers. This behaviour made USB3 Enclosures unsuitable for DP. I have to connect those to the same ASMedia eSATA PM controllers and I can individually hot swap the disks w/o affecting DP.
So let me emphasize that DP is really nice. I just need an elegant way to deal with the USB enclosures' bays going offline all at once.
I'll see if I have the time to run the Troubleshooter on the Windows10 VM (I'm half way through the trial license ) I'm basically trying to build a remote backup setup using the 5Bay controller with DP and hook them up to a laptop or something.
