Reclaim lost (unpartitioned) space on Fusion disk First my Bootcamp crashed due to a Win update on my iMac. Then I tried to fix it, assisted by an AppleCare person (using Diskutil and Terminal). Now it seems I have lost 500GB+ on my Fusion drive, and I have not been able to restore Bootcamp using BA. 

I know very little about terminal, and don't know for to regain the lost space and make the fusion disk ready for setting up Bootcamp again. Help would be very welcome!!

Thanks!

I'm attaching a couple of screenshots that probably shows the situation currently.
I believe the commands below will return the free space to your "Macintosh HD" volume.

newfs_hfs  -J  -v  "Recovery HD"  /dev/disk1s3

diskutil  unmount  disk1s3
