A while ago, I had a Boot Camp partition. There were some errors initially when I removed it, but the partition did eventually go away. I need Windows again, so I'm about to do Boot Camp again. To prep for this, I ran Verify Disk, and there were some errors, so I booted into the recovery partition and fixed them. Now, back in OSX: Disk Utility is showing 156.47GB used, 93.67GB free. Finder says it has 205GB free. (I have the 250GB drive) very weird: while I was typing this, it changed. Disk Utility is showing 156.52GB used, 93.62GB free. Finder says it has 208.18GB free. Disk Utility reports no errors on this partition. Does this sound like a hardware problem, or should I just do a complete wipe of the drive and re-install?
