I don't think it's a hardware problem at all. All four are standard USB EHD work on any computer and supposed to work on Dish. They worked good for over a year until locked out by the update on Oct 21st. If it was incompatable drives,buggy drivers,bad controllers or drives they wouldn't have worked for the past year. I gave up one of the inaccessible 2tb drives, reformatted it on my PC and dish H3 saw it right away,reformatted it and it's been working fine for 4 days now. No hardware problem. I don't want to give up the other 3 drives with 6tb of shows. I agree that if dish is such a POS and they never fix this for the many people that have called in after the update I may have to start swapping controllers and drives as a last resort and load it all in the PC as MPEGS as I ride out the end of the contract and cut the cord , can the H3 and go to the cheaper streaming like lots of others.
