Hi. I got a new iMac in January. I decided to install Windows 10 to 2.2TB Fusion Drive. Boot Camp started, but got stuck making a 300gb partition. After force quitting Boot Camp, the iMac Fusion Drive HD reads 1.8TB. There is no listing of a 2nd drive or partition in disk utilities.
How can I recover that invisible, missing memory?
Help.
iMac, OS X El Capitan (10.11.3), Fusion Drive 2.2TB
The simplest and safest method to get your disk space back is
1. Backup OSX and all your files - Use Time Machine to back up or restore your Mac - Apple Support .
2. Boot into Internet Recovery (Command+Opt+R) - OS X: About OS X Recovery - Apple Support .
3. Click on Utilties -> Disk Utility and Erase your internal whole disk.
4. Restore OSX and your files - Use Time Machine to back up or restore your Mac - Apple Support .
This requires a separate external disk which can accommodate TM backup - Backup disks you can use with Time Machine - Apple Support .
Thanks Loner T. I'll start working on it. I was hoping for a less drasticfix!
There are fixes using Terminal and diskutil commands, but a backup is still required. The Diskutil commands will just build the Fusion disk faster and can be done in Internet Recovery.
Force quit boot camp while partitioning, HD memory reduced.
