Hey I had a partition in Exfat to share my music between my windows partition and my mac side. I was using itunes to play the music on the exfat on the mac side and then suddenly my computer gave me the 'you need to restart your computer' message. I restarted and now my exfat partition doesnt show up on my finder, on disk utility it is there but it is in grey writing and it cant be modified. When i do repair disk on it, disk utility says everything is ok!? I can just delete this partition and re-make it and get my music off my iphone, but will this happen often? The partition only lasted like 12 hours... Also I can't try it from the windows side as I recently deleted windows to re-install the 64 bit version since win7 32 bit only supports like 2GB of ram..
