Q: I need to sudo cs delete an encrypted hard drive but get an error "Not a valid CoreStorage Logical Volume Group UUID"
Ok so I encrypted an internal HDD with DOE compliant encryption, and forgot the password. I am not using a typical mac bootloader so apple C when its booting will not work to delete it before its mounted. I have to do it through the terminal. The drive I want to delete is HDD2. Here is the screen capture of running diskutil cs list in terminal.
Then I disconnected everything to avoid problems, leaving my encrypted HDD only, copied the UUID, it's in this format:
diskutil cs delete XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX
But I am unsure which group or physical UUID I need to use, there are three associated with HDD2, logical volume group, physical volume and logical volume family. I thought before pressing enter I better ask first ... as I tried it on the physical volume first and I got the error in the title so dont want to start guessing what do to.
Thanks

You want to delete the LVG corresponding to the CoreStorage volume you can't unlock. Doing so will irrevocably destroy all data on the volume.
