Fun fact debunked: DISH only charges an EHD activation fee on their ViP211(k) non-DVR receiver that converts it to single-tuner DVR functionality. This is a capability not shared by the DIRECTV H2x series of receivers.
EHDs are free to activate on all DISH HD DVRs and doing so doesn't disable the internal drive nor force you to reprogram your recording preferences. Additionally, DISH EHD recordings can be shared among all HD DVRs on the account; something DIRECTV hasn't seen fit to implement.
I meant to edit that out as it kiltered off topic, but from page 10 of their Commercial Customer Agreement Exhibit 1-Fees it states a one time forty dollar charge to connect an external hard drive to any ViP receiver. The ViP 722/ViP 612 is a HDDVR reciever, so their customer agreement would seem they charge the fee to that receiver as well but it may be a fee listed on their agreement they do not actually charge anymore. And again, this is very off topic which is my bad. If you wish to discuss further please do so with me via PM as we can get back on topic as this is not a Dish vs DirecTV external hard drive thread.
