Hi apocbane, did you find a solution to this?
I have a similar situation, i installed a second, identical SSD - also the X25 G2, to run raid, the SSD died, and i haven't been able to see it in the BIOS since, i suspect we probably have a similar corruption...
Sadly I don't think there is much we can do other than RMA. Maybe if the drive was still seen by the BIOS it would be recoverable, but since not, no actions can really happen.
I installed my OS on another drive and moved on. This isn't the first problem with Intel's firmware updates on these drives.
I'm sorry for the trouble you are experiencing.

Thank you Jim.
I've proceeded with the RMA after talking with support.
I believe the root cause to be it being a drive i used for Win 7 OS. Trying to flash via windows wasn't the best idea.
If you plan to flash the firmware on this drive and are using windows 7 actively on it, i'd go the downloadable CD route.
Booting to a CD should free any type of locks on data sectors and enable the drive to be flashed successfully.
Normally this is my standard route for all flashes (through boot, not OS)
