My MBPro locked up while partitioning the HDD through Boot Camp Assistant. I had 120GBs free and was setting aside 70 for the Windows partition. Rebooting after the crash there is now 50GBs free (as if the partition was created and is being accounted for) but there is no visible partition. Starting up Boot Camp Assistant does not give me the option remove a partition but instead the option to split the remaining 50GBs of space, which of course does not work. Do I need to do a complete wipe of my HDD to get the half-done partition back? Any other ideas? Thanks.
