Wd 4tb raid 0 permission isscue?

Hello,

couple days ago I got my new WD 4tb external HDD. When I connect drive to computer by usb or firewire in my computer I see HDD but can’t write anything on it. I got message that I need administrator permission what is little strange because I’m loged with admin user. So, I’m format drive to raid 1 and get 1.8TB capacity and everything goes fine. Now can’t back hdd on raid 0 because this option is not availiable in WD drive manager.

Anyone have suggestion how to back drive on raid 0 and what coud be a problem??

I using win7 x64.

Regards,

BA

Hello,

Could kindly let me know exactly what drive model do you have? also if possible download the latest version of drive manager from the WD website.
