Hi,
I want to create space 30GB of my SSD that are not used, it should bee unpartition.
I have fixed it in disk utility but it's still formatted, I want it unformatted so how can I do that?

You can do this in Terminal with this command:

diskutil erasevolume free %noformat% <disk>

Replace <disk> with the partition that you want to delete, e.g. disk2s1. You can find the identifier with

diskutil list

Be aware that Disk Utility is fairly bad in handling free space. You will likely not be able to partition that free space in Disk Utility, leaving you only with diskutil.
