I have two My Book Essential 3TB . When I installed both of them everything was OK. I could open any files such as video, image and text quickly without any problem. But now it takes a long time to open any files. It’s frustrating. I appreciate if anyone can help me to solve this problem.
Make sure that the drives power adapter is directly connected to a wall outlet, then try diff ports or cable. I believe this would be a cable issue. Or try to run a check disk or diagnostic test on the drive. http://wdc.custhelp.com/app/answers/detail/a_id/940/session/L2F2LzIvc25vLzEvdGltZS8xMzYyMTIyNjE3L3NpZC9PVFV6bTJrbA%3D%3D
Thanx a lot for help. Drives power adapters as you said were not directly connected. I connected them directly and now everything works perfectly fast and smooth in both drives. Thanx again & god bless you
