Wow, getting a reply from Lacie on the matter is impossible - either I can't express myself or their support don't read the message. check out this, bare in mind it is posted in connection to my drives, which they have the serial numbers of. Maybe lacie can respond here?

Hi there
I have this drive and several others (lacie and non-lacie) operating as RAID 1. I also have a new Lacie esata Thunderbolt hub (which I may return).
I am trying to understand if this drive and my non lacie drives are operating as RAID 1 with full mirroring, when used with the Esata hub, or if just one of the drives within the enclosure is being used.
Is there a way to test this from my mac, as it would help me to understand both this drive and my non-lacies are working correctly and fully with the Esata Hub.
Similarly, would this drive work as full RAID 1 with an esata to usb3 adapter?
This is what your support commented on a forum comment of mine:
"We would need the serial number of the LaCie drive to answer if it is true RAID or not. I can say that our LaCie Thunderbolt/ESATA hub doesn't support port multiplication. ie an enclosure containing multiple disks may not be fully recognized when connected to the HUB."
Ideally though I would prefer to know if there is a tool I can use from my mac to understand how the drives are being viewed.
Thanks
Jonathan A.

Good afternoon,
My name is Jon and I will be working with you on your issue going forward. The thunderbolt/eSATA hub itself does not act as a RAID controller but rather as a hub as one would expect for a USB hub or firewire hub. Depending on the make and model of your hard drives the RAID control would either be hardware based as on your 2Big quadra or software based as from your Macintosh's disk utility. For a software application LaCie does not have such a program on our support site nor do we maintain an official list but it's feasible such an application can be located from an online search.
Best regards.

Thanks for your reply but I don't think you have answered my questions.
Firstly I want to know how my specific Lacie D2 Raid drive will work via the hub, and secondly I want to know if there is a way to see how my other RAID enclosures work through the hub. To clarify:
I have the D2 Quadra Raid enclosure (2 x 1TB) . According to your colleagues who answered my forum post on mac rumours, some Lacie Raid drives will work as Raid using the esata hubs, others will not. How can I tell if mine is true raid and working as raid?
I can't see the serial number on the drive but from my registration details I think it is this one:
Serial Number: [removed] Purchase Date 01 November 2010 Warranty Expiration: 18 August 2013
Is this "true Raid"?
And aside from that, all my RAID drives are 2 drive enclosures that I have purchased for the RAID purposes rather than pairs of single drives with software raid controllers. I use them all as RAID 1.
Lacie support in the forum said that not all RAID drives (Lacie or otherwise) will work as RAID using the hub, but some will not as not all RAID enclosures are supported through the hub.
So is there a way to understand how mine are being seen through the Hub - are they being seen as RAID mirrored drives or as single drives? Is there a way to know if the hub is supporting RAID in the case of each of my RAID enclosures (I have two).
This is really important to me so I would appreciate your help.

Good afternoon,
The hub you refer to allows for you to connect more than one device at a time while using one port on your Mac or Windows PC. This act of connecting multiple devices onto said hub does not automatically create a RAID array. This is done on the device in the case of your 2Big or from your Mac's disk utility for a software RAID (i.e a 2Big thunderbolt).
Either way, your drives would appear no differently connected using your hub than if separately connected.
Regards.

Sorry I think you are still not understanding the question.
I know the drive does not create a RAID array.
As you can see from my registrations on Lacie, I own Lacie RAID enclosures. They are already RAID drives. If I connect them directly to my computer they will always operate as RAID.
However LACIE support on the MacRumours forum told me that not all LACIE RAID enclosures will operate as RAID via the hub. Some will, some will not. Those that do not won't appear any differently, but only one drive within the enclosure will be active.
How can I tell if my Lacie RAID drive is operating as a RAID or as a single drive when connected to the hub?
I'm really not sure how to express this any more simply.
Again, for clarity.
I have a lacie raid drive with 2 spinning disks in a single enclosure. It is designed for RAID and on the back the SAFE light is lit.
I have the lacie esata hub.
When I connect the RAID drive to the hub, is it working as RAID or as single drive?
Thanks
