I don't know what the possible cause of that would be, and Vorbeth I'm certainly not blaming you (I knew what the risks were when I started playing around with this,) however, I think at the very least a "don't format SD cards while using this ROM" warning is probably a good idea.

I can tell you right now, that what you guys did is considered a BIG NO! on the custom rom scene. By formatting SD via the rom itself you are asking it to run certain scripts that are in no way finished for cm9. These scripts come from AOSP and there is a reason why it is recommended to go to recovery and format there.
You have been warned.
Also, FYI, I'm not so sure that was a brick. Were you able to get back to the bootloader after format, if so, I can already see what that format did.
