I believe Hopper will see no more than two EHDs at a time.As a side note I have discovered that the Hopper does not like having more than four usb devices plugged in at the same time. Even though the Hopper is supposed to accomadate up to four EHD's with a powered hub since I already had the OTA adapter and WIFI dongle using two of the usb's the hopper would not show a 3rd EHD plugged in to the hub.
Once a WD has been formatted for Dish, is there a way to turn off the sleep mode?
My Seagate never drops out. It sounds like this issue usually happens with WD, maybe others but WD is the trend I see.
You're lucky.
