Kernel Securit Check Failure with External Drive

Ah sorry. It says 'Kernel Security Check Failure'.

Hi and thanks for you quick responses. Unfortunately the LaCie only supports TB, and I have tried both ports on it and all 6 on the MP. It is currently the only TB device I'm using, and works fine when I boot to OSX. It appears to be working when I boot to windows, as it doesn't spin up unless it is connected to a computer (it spins up when windows tries to boot). I did get a windows recovery screen after trying to boot several times. It was unable to restore to a previous image using the automated tool, and none of the available boot options that I tried achieved a successful boot with the LaCie plugged in. It seems the only viable option from that screen would be to reset windows completely, but I'd like to avoid that if I can.

Oddly if I plug in the drive after windows is booted fully the drive spins up, but nothing happens on windows. I remembered that I had set a partition on the drive to not automount with the fstab on the Mac side. I tried removing that setting to no avail. Does windows have a similar construct that could be causing issues?

Re Updates: There have been none that I'm aware of. Is there anyway to check?

Also, I checked Device Manager and Disk Management, and the drive doesn't show up in either location.

To explain: disk0 is my internal SSD, where Bootcamp lives, along with a small storage partition I use on the mac side (called 'Mac')

disk1 is the first of two disks in my LaCie. 'Crumpled Paper' is my boot drive for mac, 'GAMES' is where I store my windows games.

disk2 houses my backups (its also in the LaCie).

Only the SSD shows up on the windows side at all. I can see both partitions of the SSD on the windows side.

Hehe great show. Seemed an apt name for a Time Machine. Now I just need the bowtie!

No I can't see Games or any of the other partitions from disk1 and disk2 (the two disks in the LaCie), only the partitions on the internal SSD.

I haven't heard of fast boot before, but I checked and it's not on.

No dice. Turning fast boot on and off didn't have any effect that I could see. Restting the SMC got me a "Please Wait" message at the bottom of the regular windows boot screen, but still resulted in the same BSOD. The LaCie disks still don't show up anywhere in windows if I plug them in after it's booted.

Worth noting: They do have instructions somewhere on their website for installing a specific driver to allow it to work with windows. I never did this because it always worked fine. Since the drive doesn't show up in device manager now, I can't install it (as per the instructions). Don't think this would be the issue because the drive worked fine before, and also the intructions seem focused on making the drive usable after windows recognizes it, which isn't the problem here. Still thought it might be worth mentioning.
