How to reset 3TB fusion drive to original partition scheme
When I first purchased my 27" iMac in early 2013 I was unable to use Boot Camp to create a Windows partition (with the version of OSX it shipped with bootcamp was initially disabled but added in an update later). I found a guide online for untangling the Fusion Drive partitions and essentially setting up bootcamp manually.
However, a few days ago I had Windows 8 get screwed up and needed to reformat. I figured that since Apple now updated Mavericks to allow my machine to use bootcamp I would start from scratch and do it properly. The problem is, I cannot seem to get my machine back into a "factory default" setup. I tried removing the CoreStorage volume and letting the Disk Utility tool "reset" the drive, and that -seemed- to work. I had one 3TB partition (according to the GUI) and re-installed OSX. I used Bootcamp to split 2TB for Windows (games) and leave 1TB for Mac. Everything went fine and I restarted into the Win8 installer. However, at this point Windows refused to install to the 2TB partition. I tried formatting it, and delete/create but it said it couldn't install to that partition. The confusing part is that according to Windows I had about 8 partitions (EFI and Recovery I understand but the rest I don't know the reason for).
So now I'm back at the OSX Recovery and this is what "diskutil list" is giving me. Why are there all these 524.3 KB partitions? I can't seem to remove or merge them. I know I should have recorded what the original structure is, but it's too late now. Can someone tell me what the 3TB Fusion Drive *should* look like, and how I can get back to that?
