Z20 PRO - How to get "write" access to internal HDD

I don't understand people who ask for help, but when they solve their problem, they don't want to help others. But no one is obliged to help me.
P.S. Thanks to Faceman2k24 for engaging with the thread and helping to resolve the issue.

 

If it isn't working for you then something is either missing, or something is different in your system in some way.

All I can suggest is to nuke it all and start from scratch
