An External Hard Drive (EHD) allows you to expand the disk storage of a DVR (Hopper, 922, 722k, 722, 622, 612), or enable the DVR feature on some receiver models (211k, 211, 411). The EHD must have its own power supply, support USB 2.0, and have only a single hard disk drive (flash memory is not compatible).
