I lost disk space resulting from a failed Boot Camp run. I was trying to create a partition to run Windows 10. Bootcamp failed to make the partition, but the allocated drive space disappeared. This has been covered in another Ask Different thread where I got apartial solution. The command: "sudo diskutil cs revert [Logical Volume guid]" will recover the space, but I need more details. See: Missing Space on Drive using Core Storage after Boot Camp Assistant Failure

MY QUESTION: I need clarification on the command – What is the right value for [Logical Volume guid]? This could be a dangerous command. Here is my diskutil list:

I have a MacBook Pro Retina mid-2012, 8gb memory, running High Sierra.

Any help appreciated, Rolf

  • No disk space is missing. The Apple container disk1 reclaims 99.9% of disk0. CoreStorage is not enabled on your disk. Instead it's formatted with APFS. You better add the output of diskutil ap list! – klanomath Oct 30 '17 at 15:52

Answer: Yes, disk space was in fact missing. "Get Info" on Macintosh HD came up 30gb short.
Solution: I backed up the whole disk to Time Machine, wiped it, and restored. Needed some follow-up fixes to things like Google Drive, but all-in-all, it went well. -Rolf
