gwwyrovsky 0 Posted April 2, 2012 I want to connect an external hard drive to my Bosch 600 series DVR through the USB, but the unit does not recognize the drive. I know the DVR is picky even using flashdrives, but does anyone know a way to connect a Western Digital drive (cost about $150) instead of buy a Bosch drive (equivilant size, about $700)? Thanks in advance. Share this post Link to post Share on other sites
