Can anyone help solve this problem, I was partitioning my main volume (400GB) and my mac crashed during partition. When I started up again, my main volume is saying I only have 93Gb's left out of a possible 500Gb, before the crash, it was roughly 400Gb. Is there any way of recovering the missing capacity (have ran disk inventory and can't see any hidden files) without resorting to installing the OSX again and all the programs (trying to avoid this as I've just spent the whole day doing this). Thanks.
