Hard-Drive Storage size issues after partition Disk Utility
I wanted to create a partition on my iMac for Windows to be able to play Windows games. I have used Disk Utility to create a 20GB partition on my 1,12TB Fusion drive. This caused a problem on my system.
The partition was not created, but my main Macintosh HD drive has all of a sudden 1,09 instead of the 1,12TB available.
It seems that my ghost partition has been created, but it is unfindable. When I try to create a new partition I get a direct error telling me that my coreStorage volume has a wrong size, so i'm not able to create a partition.
I have searched the web and found some terminal scripts to resize the size of my HD, but this did not work. I have done the following steps:
Check the real size of my drive and partitions through terminal diskutil list

Error: -69674: The provided Core Storage logical volume has an incorrect size; you should run whole-disk repair
I have check the drives with "First aid" in Disk utility and everything came back fine, so I think it is only a storage amount issue.
Does anyone know how to solve this? and make sure I can restore the full amount of storage on my HD in order to create a new windows partition?
Thanks!!

To run a whole-disk repair, you need to do it from the command-line:
diskutil repairDisk /dev/disk1
Be sure to use the correct disk identifier (in this case it was /dev/disk1
); in diskutil list
you're looking for a disk marked physical
in order to specific the entire physical disk (i.e. not a logical disk). If you incorrectly use a logical disk identifier instead, you will get the error: You cannot specify a CoreStorage logical volume (and a logical volume should not have a partition map)
