Hi there
A have many problems with my my cloud ex4. When i connect a USB drive to the unit the EX4 stops responding and i can’t se it in the network. I have to reboot the EX4 the hard way. After rebooting and i plug in the USB drive i manage sometimes to connect to the EX4 and the USB drive via my PC. When I start copying form the USB drive the EX4 becomes very Slow and after the file copying the EX4 are missing many files. What is wrong ? I am desperate now. 
I think I just have to return the EX4 to the dealer. 
Kind Regeres

What have you tried so far? Does this happen with other USB drives as well? Did it use to happen in an older firmware revision?
Hi Trancer
I performed a HW RESET on the rear panel yesterday and now I can attach the 2TB WD my Passport without problems. I also followed the procedure about installing a certificat in the myCloud signin in MS Explorer, not in Chrome. I hope it works, so far it’s looks so. I am optimistic now.
Kind Regards

hi soren,
tell me please, how you do the “hw reset”, i have the same problem with the usb drives…
thank
You take a paperclip and activate the RESET button for 5 sec. The EX4 must be on.
ok thank !!
and this procedure delete the data?
No just the system, the data on the drives stays.
