My Book 500gb USB 2 Problem


I have a my book external drive and the problem that i have is that i cannot cut and delete files from it and cannot paste files in it. The windows shows me that the disc is copyprotected. In fact the only solution that i have find is from dos the command i use is attributes but every time i have to restart the problem is there and i have to do all the ettributes procedure again? What can i do?

Go to the drive properties and take ownership

assign full access 

I already have tried that. It does nothing and i also have formated the disk and still nothing…
