In this video, I go over the setup procedure on a Channel Master DVR+ CM-7500GB16.
Sabrent USB 2.0 to 2.5″ drive enclosure EC-UK25 (https://amzlink.to/az0igr4khFj2d)
WD Red 1TB Hard Drive (https://amzlink.to/az0XnDD2vCe3z)
Sabrent USB 3.0 to SATA 2.5 or 3.5 enclosure EC-DFLT (https://amzlink.to/az0QjSwCkxNm3) This is a larger enclosure. I would recommend the smaller enclosure unless you have a 3.5″ drive.
