So my 10 yr old 1TB EHD just died. I had a WD MyBook which was about the size of a brick. Seems anything 2TB or less from WD is now considered "portable" and is the size of an iphone. Not sure if these "portable" ones will work well with a 211k. I believe the EHD cannot fall into sleep mode, and I dont want this small portable drive to overheat. Can I go to 3TB or 4TB on a 211k? This way I can keep WD as the manufacturer with the same sized "brick" drive that I used to have. If not, any other alternatives? I cannot order the 2tb drive on Dish's website for geographical reasons... funny how they seem to have stock on the WD 2tb brick size... Cant find them anywhere where I am.
