What is set to "No Access’? Are you accessing the USB drive locally or remotely?
Couple of things to try. In the Dashboard, navigate to Settings > General > Cloud Access > USB Content Availability = Off. Set the Public Access setting for the USB Share to off. Again in the Dashboard, navigate to Shares > select USB Share > Share Profile > Public Access = Off. Then in the User Access section on the Shares page one can set the User access to that share; No Access, Read Access, or Full Access.
Yesterday all shares could be accessed by anyone. Regardless of what the settings were. At least after a Quick Restore, it fixed that, but now anyone can access the USB drive still.
It looks to me that there may be a misunderstanding of what is the primary function is for those external USB drives.
As far as I can tell (from using an attached USB drive) it will be unavailable to local net users if the [USB Content] = ON regardless of WDMyCloud security settings and will appear as just another network attached drive.
Like me, if you are using that drive for Safepoints and you do NOT want any user access to the drive then set [USB Content] = OFF and use the drive for just Safepoints.
I believe that the primary function for the USB external drive is backup and not additional NAS space. Just my SWAG.
But it creates the drive as a share, and I should be able to set Full Access, Read Access or No Access. At the moment, even if I set it to No Access, all users have access to it via FTP. Also, I have it mapped on my PC, and regardless of the access setting, I can still access it.
This problem just started with the last firmware update.
It’s a bug. I hope someone else can try this and see if they have the same problem. Try turning share access off for a user and see you or whoever can still access it.
So, I just went through the WD documentation for the MyCloud and the extra documentation for the FTP access and when set up according to these documents FTP access IS secure! Users have no access to the USB drive unless they have user access to the share and have FTP rights and (most importantly) have a password.
I ran these tests using a depreciated Windows user (meaning, not an Administrator) and with no special access. This user can only access the Cloud PUBLIC shares and, of course, the FTP shares I allowed that user rights to.
If I log into Windows as a standard user, and attempt to access WDMyCloud dashboard, or the WD Quick View, or FTP into the device and download or just attempt access using Windows File Explorer, I am refused.
But if I use the WD MyCloud application then I can access all of the shares on the WDMyCloud! This is unbelievable!
How are you trying to access the My Cloud? By IP address or hostname? I’m logged in as a standard user, on my windows 10 laptop. I can access the dashboard. I have access thru the file explorer. I have the My Cloud set up in the router ti always get the same IP address.
