I have since 3 days the WD My Cloud EX4 without drives. I installed 1x 1,5 TB harddrive into slot 1. Everythink works fine.
Yesterday i made a update to FW 1.05.21, after update the system the HD and system LED’s are flashing red. I put the 1,5 TB disk into slot 2 an everything work.
Did everyone know this problem? Why will it only works when the harddrive is into slot 2 and not 1? I used JOBD for RAID.
