Read only My Book Live Duo

We can access My Book Live Duo but when we edit our files, it always says the folder is read only. Whenever we change read only, it always goes back to being a read only folder. What can we do to solve this?
We are using Windows 8

Hello Fountains,

You can try to reset the device once and then see if issue persists.

You can see more information about resetting your device on page 128 of the manual.
