Please include the ability to make USB shares private. Currently, USB shares are public and open to everyone. The NAS is unusable as a shared device unless all users are assumed to have full read/write access to the data on the USB device. Apparently, previous versions/generations of WD NAS did not overlook this critical feature. This missing feature seems to be a glaring omission in the EX4.
I created a new idea for the EX2 product ( http://community.wd.com/t5/Personal-Cloud-Ideas/EX2-USB-shares-need-configurable-permissions-configurable-ftp/idi-p/712500 ) with the same request for USB share permissions on the EX2 (this idea here is for EX4 so not sure if it would apply to EX2) - but also added two supplementary requests: 1. Need to NOT share the entire USB drive but rather certain top level directories on the USB drive and turning ftp ON/OFF on the USB share 2. Currently if I enable FTP access in Network settings, then the USB share automatically inherits that property instead of like the EX2’s shares where ftp access is set on a share-by-share basis.
Please click the up arrow on the above linked page to vote for my suggestion.
Here’s a manual fix to make USB shares private until WD deems a firmware fix is necessary -> http://community.wd.com/t5/WD-My-Cloud-EX2/Hacks-to-make-Public-share-and-USB-shares-private/td-p/728740
