    Hi, I bought the 2012 Mac Mini last year and did the DIY Fusion Drive on it with a 128gb SSD and the stock 1TB hard drive. For some reason though instead of seeing the 1.13TB it should be seeing it only reads as me having 700gb to work with. Any reason why this is happening and is there any way for me to fix it without having to split the drives and start over?

    Perhaps part of the answer is the CoreStorage partition and volume manager Apple uses with FusionDrive. So perhaps the CoreStorage logical partition volume group is using up, or has set aside, more space on your hard drive.

    Also, did you partition your drive, or use bootcamp? Note a partition on Fusion Drive makes a partition on the hard disk only, i.e. it is physically located on the hard disk drive, not the "fusion" drive and it is not part of CoreStorage.
