I just received my HR44-500 DVR this past weekened, and while I understand it has a 1tb internal HD, I want to put a larger HD on it. I did a search in the forums for maximum hard drive size and founds some posts dated back in 2010 that basiclly said that 2TB is the maximum. I already have a 2TB eSATA drive on my HR22-100 and it works great. Now that I'm purchasing a new external HD for my HR44-500, I want to know if I can spend the extra $100 and attach a 4TB eSATA hard drive to my HR44-500? Yes I know that is a large capacity drive (and might be overkill), but I in my household people record A LOT of suff and I want to ensure they have space to record it. (The 2TB drive sits at 30%-20% free and that's with me cleaning house every now and again.) We like to record entire seasons of shows and watch them back to back (and sometimes many seasons worth - we like to know a show isn't going to be cancled before investing our time). Specificlly I am looking at this hard drive (I have used the same brand on other HD receivers and have had great results and customer servcie from this maker).
