There has been a problem with my external hard drive being recognized since I got latest software S515 on December 5th. At first I could reset the hopper and it would once again see it and work. This week it didn't see my external hard drive at all and the drive didn't light up. So I plugged in my older hard drive that had been on my 2nd account for my parents-they never used it much anyway. It recognized it and then asked to reformat it -since it was associated with another DISH account. I hit yes and it worked and I transferred some Christmas shows to it and it worked. I then unconnected it and plugged in my original hard drive and watched a movie from it. I have like 200 movies on that one. Then the next day it was once again not seeing my hard drive. I tried all three different resets and it failed to recognize any hard drive. I unplugged the hard drive and then waited till today and plugged it back in and still no recognition of either hard drive. I plugged in the usb plug to my front usb port ,just to see if it would see it and no go. So now I figure it has to be the hopper itself ,even though it is only about 7 months old. So my next step is to start the tech call and get my hopper replaced since it no longer sees any external hard drive at all.
