Ok, so I got this new L627 update and it wiped my external drive. Wants it formatted now. Lost all shows and of course when I called dish to find out all the way to advanced tech support they say they've never heard of problems with the external drive and never heard of a firmware update that has crapped out an external drive. F you dish.
I have an EHD that does this to me more often then not. You just have to turn it off and then back on again until it is recognized. Some drives are less useful as an ehd than others.
I hope you didn't FORMAT the drive...
