Hi all. Fellow late 2012 iMac user here, got the 3TB fusion drive and a bunch of other goodies with this baby the day of release. My goal today was to successfully use bootcamp to make a partition for win7 - I had the .iso all ready and just had to set up an install drive. I didn't have any big enough flash drives on my hand to get the job done, so I just grabbed my handy 1TB external drive and decided to install with it instead. I had about 88 gigs of data on it already, so just copied it over into a folder on my iMac and ran bootcamp in order to set it up. It did so successfully, and from there I decided to partition a good 505GB for windows. Here's where things got bad. After waiting a good 30 minutes for bootcamp to make any progress on the partition, I got impatient and decided to cancel the operation and verify my disk using disk utility. I simply pressed "Cancel," and as this did not actually perform any direct action, I then quit the application (NOT force quit). I tried opening it up again directly after this, and bootcamp would not launch; would just keep bouncing and showed up as unresponsive under force quit menu. From there I open up disk utility to directly verify my disk, and a few minutes in I realized I made the mistake of verifying while logged in. Stopped the verification process, tried to close out of the window, and was met with the confirmation message asking if I really wanted to cancel (I think there was some form of warning against corruption if you do this during certain operations, but I ignored as this was just a verification). Cancelled, and then restarted my computer while holding down CMD-F for recovery mode. Open up disk utility under recovery mode, and this is where I notice the first problem. My hard drive capacity is showing up as 1.8TB, even though it's obviously 3TB. I verify the disk, and it throws a few errors and tells me to repair. Upon attempting to repair, however, the "Disk utility can't repair disk..." thing popped up and of course frightened me. I exited disk utility and restarted my computer, and luckily everything was working as normal (other than weird hd capacity). I decided the best thing to do would be to just back up my data (luckily I only have about 86 gigs of essential files), erase the hard drive using disk utility, and re-install OS X. At the moment I am 3/4 through backing up files onto an external drive, I plan to simply start fresh and copy over the individual files I need. Any thoughts? I don't want to hurt my $3k machine. Thanks.
