My 2 Hopper 3 receivers still have issues with my 3 western digital external drives. One time my external drives stopped showing up on my Family Room Hopper3. I had to power down the drives and when they powered back up they showed up.
Also, playing content on all three external drives requires the following steps:
1) Select external drive from sources
2) select a program on the external drive
3) Select Start Over
4) Error message shows up for 1 sec saying drive needs activation
5) Get blank screen
6) Hit Guide and select a new channel
7) Get error message 314 Your request can only be carried out in live mode. Switch to live mode?
8) Select Yes
9 Repeat steps 1, 2, and 3.
10) The second time the external drive program works.
All of my external drives are Powered Western Digital 2 terabyte drives. They all worked all the time with the old interface on my Hopper with sling receivers. I should also tell you that my 3 external drives range in age from 2007, 2010, and 2016. My one drive has 100 movies, the second drive has 57 events and the third drive has 75 programs.
Last week at 2:30 AM I woke up to see my Joey 2 powered on. The Joey 2 had error 1303 - Looking for Hopper. I turned on the Family Room TV which is connected to my Hopper3. It displayed message 770 - Checking External Hard Drive. A routine test is being performed on your external hard drive. This test can take up to 50 minutes to complete. Once the test is completed or stopped, your receiver will reset. The reset process should take no more than 5 minutes to complete.
It took approximately 2 hours for the Hopper 3 to complete the drive tests but I do have 2 hard drives connected to that Hopper 3. When it finished, I checked and all of the content was still present on the drives.
By the way, I have no problems transferring content to and from the Hopper3 and the external drives.
I have talked to Dish Tier 2 support and they are aware of the problem. They claim that Dish is working on the problem.
What surprises me is that some people claim to have no problems playing content on their external drives. The Dish technician told me that the problem exists.
