Currently have (3) HR24-500 and would like to upgrade the HD. Any recommendations on an external HD that works well with these receivers? Also, I plan on adding an external HD on all receivers. Possible?? Lastly, would this work even with the whole home DVR service?? Please advise and thank you for your time.
Yes you can add external hard drives to all of them, and it will work for Whole Home DVR service.
As far as which hard drives to get I recommend you go over to DBSTalk.com and look for the thread on there about external hard drives. I know at one time the HR24-500 had an issue with a lot of external drives, but I think some people have had better luck lately.
