Missing disk space after failed bootcamp partition

So a bootcamp installation failed and now I'm out 400gb of space on my drive. The only partitions on my computer are now the main Mac HD. No bootcamp partition or anything, its as if theyve merged but the space has vanished.


I checked the drive with "First aid" in Disk utility and everything came back with no errors.

Sorted it with:


diskutil repairDisk /dev/disk0 


From recovery mode.


Now I just need to figure out why I can't partition my disk anymore. Tried three more times but in all instances it hanged after reaching about half-way in the creating partition stage. Got no local time machine snapshots (they're on an external drive), so its not that. Ugh.

Ok tried making a smaller partition, 10gb.

   0:                            Boot Camp              +1.2 GB     disk3


Took 5 minutes. So maybe its the size of the disk I'm trying to make?


Note: the disk3 boot camp partition appeared after I downloaded the windows support software. I'm guessing thats usual behaviour

Got it sorted. Partitioned and removed incrementing the size as I went. 50gb - 100gb took 20 minutes. 100gb - 200gb took 50 minutes, 200gb - 250gb (original partition size) took an hour, 250gb - 350gb 20 minutes (shorter?), and finally 400gb took 12 minutes.


After that I did it with Bootcamp assistant which worked in 10 or so minutes but it failed to copy the windows files over. The ISO was too big for the partition format. So had to source an older copy with a smaller size (1709).


That then worked but when I got to the windows installation, notably the partition selection screen, I was met with the error 'We couldn't create a new partition or locate an existing one'. This was solved with a PRAM reset..


After that everything was gravy. Was up and running in around 10 minutes after that.


Thank-you for your help
