I am trying to use the hard drive from my dead laptop as a portable storage device in a caddy to run between my desktop, new laptop and chromebook. Windows 10 is on the Desk machine, and also on the laptops HDD. I want to format the disc from the laptop (I guess that I need too in order to remove the Windows and Windows.Old folder from the HDD), but need to migrate the data files over to the other machine first. Windows from the desk top (target machine) won't let me move or delete certain files and folders because I don't have permission. Is there a way to do this globally across the whole disc?
