Hi, I just got a EX4. I saw a message explaining new Ex4 cannot set share and permission on external USB. I am having same problem, but it is not true. When I first setup my Ex4, I use Raid 10 and I connect Seagate 4TB external drive. I formated over mac os x and I was allow to created a share folder inside external drive, I created 4 folders then I disconnect from Ex4 and connect to mac. I saw the folders there and start moving a a 3TB of data. Then I probably upgrade the firmware while I was copyng all that data, specially because took so long. When I move it back with firmware updated I got error in file limit and I was not be able to create folders anymore.
I formate whole external drive and no way to create folder and set permission over external drive. My question is, anyone who have problems is running the new firmare is 08 or 25?
I found old one over the internet , downgrade using dashboard and after I move all data from ex4 I will try full reset and see if the connected drivers show up in the share disk dropdown.
If anyone find fix, please post here.
