That sounds insane!!!
Well done!
Let's just say I'm never going to install the Intel Rapid Storage driver again
But in this case the Intel driver mirrored the partition table of the one 1.5 TB to the other 1.5 TB upon reboot, really weird. Thinking that it was a bad Win7 install when I got a BSOD upon reboot, I decided to install Win7 again, but this time on an empty partition of the other 1.5 TB. And surely, that drive's partition table also got corrupted. Double whammy, if there ever was a time I felt suicidal it was that day, mainly because I was really tired and things just seemed to get worse by the minute.
Anyway, just stay calm.
