My old Lacie (2012) was saying it would fail soon so instead of just replacing the drives this time I opted to get a new Lacie 2big thunderbolt 12tb drive (2-6tb). I put it in JBOD mode. And then certified the disks and then went through the easy setup and put it for mirroring. It looks like it worked from the sense that it just comes up as one 6tb drive. But this time instead of it saying mirror safeguard enabled, it says non-raid. I remember clicking on raid one in the easy setup guide and clicking on safeguard. So before I start exclusively using this replacement drive, can anyone tell me if this is normal? Or if there is in fact a way to tell if the drive is mirrored without reformatting the whole drive as I have already moved data over and started to work on that drive (although not that much so if I have to do it again, not the end of the world, but not the best).

The LaCie is pre-configured in a hardware RAID 0 format.
You need to change the hardware configuration to make this work.
Essentially, so LaCie can offer a larger capacity, they setup a hardware "Stripe" inside the enclosure. This is why it shows to be a 12TB disk. This is RAID 0. SMART data is not available for the drives, as that data is not able to be passed through.
So if either disk fails, all is lost. Unfortunately, this is not clear to a normal user.
What you wanted was a 6TB RAID 1, or mirror volume. SoftRAID cannot do this until it can see both drives. When the enclosure is in hardware RAID configuration, it "hides" the raw disks from OS X (and SoftRAID).
Launch the LaCie Hardware RAID Manager. I believe it has the ability to change the configuration to JBOD mode.
If you cannot figure it out, contact LaCie technical support. Do not let them tell you that hardware RAID 1 is better than SoftRAID RAID 1. SoftRAID is superior for many reasons, including monitoring, flexibility, predictive failure, flexibility (ability to add another disk for off site backups), etc.
