Can I change files in the recovery Drive of my system?

I am using Lenovo notebook pc and facing some issues while operating system installation. There is a drive in my laptop, which is named as “Recovery Drive” (factory setting) but I am not able to access that drive. Every time I try to access any file or folder in that drive it gives me an error saying” Drive not authorized”. How can I use that drive for my purpose or take a backup of this drive?
