40 second pin reset

I have a MyCloud EX2 Ultra I am decommissioning and selling. If I do the 40 second PIN Reset process does that remove all of the files, user info and etc that is left on the device from my previous backups?

Thanks in advance for any help!

Critical:

The process is Not Data Destructive.
It will not impact data or shares on the drive

Thanks for your reply . I was able to access the controls to r
do what I needed thru the dashboard.
