it is not possible, but with my mac disk utility and not the WD app, would it be possible?

Would be pleased if anyone out there would enlighten me.

Hello there,

Perhaps a 3rd party software could do it, lets see if another user can share some information or tips on this matter.

It is possible to use the Ma OSX DiskUtility to protect your external drive.

But it would required you to reformat the drive again. Please back your data before you proceed.
