I recently notice that my C: drive has split. I have no idea how or when it happened. It is showing as a seprate partion butI didn't make it and no one else has access to the laptop. I am using a Asus g46vw laptop with a 500Gb HDD. I haven't rebooted the machine in between the time of the split and it displaying normally. I'm running 8.1.
This is what is in D:, every in there was originally on C: except all of the install files.
