Hey, so this is an odd one..... I have a 1TB fusion iMac, and something bad just happened.. I boot from a Thunderbolt 256GB SSD. I split the 1TB Fusion into the 120GB SSD and the 1TB internal hard drive. I then installed Windows 7 on the 120GB SSD. No issues. I then split the 1TB internal into two parts: A 500GB HFS partition for OS X, and a 500GB ExFAT partition for Windows/OS X. I used Parallels Windows 7 to download a game to the ExFAT partition while in OS X. I then rebooted into Boot Camp to play the game, and... um... the drive wasn't found at all. I then rebooted into OS X, and the ExFAT partition has been renamed "disk2s3" and is not readable. What on earth happened?!
