I had an issue with a partition that refused to be deleted.
The drive is a 500 GB Samsung SSD with (previously) 2 partitions:
- Macintosh HD (apfs volume with macOS Catalina) -- 250 GB (disk0s1)
- Untitled (empty macOS Journaled partition) -- 250 GB (disk0s2)
Because the disk util app didn't work, I tried this in terminal:
diskutil eraseVolume 'free' 'delete' disk0s2
Now when I run
diskutil list it says (original image):
(I apologise for the image, I don't know how to get a text output from recovery mode)
The main issue there is that it acknowledges my drive size of 500 GB, but it doesn't show the
(free space) it's supposed to.
When I run the
gpt -r show dev/disk0 command it returns this (original image):
Beyond this I'm not sure what to do, any help or advice is appreciated.
