ocdchris 0 Posted February 15, 2012 Hey guys. I have had this DVR a couple years now. It has been flawless for me. It came with a 320G hard drive and I am at the point where I want to add more cameras. I currently only have 4. My plan is to upgrade the hard drive to something much bigger. The spec sheet says "Security Certified Hard Disk with up to 2TB of data storage". So my question is, are they saying I cannot use more than 2TB or that the unit is available for sale with up to 2TB? Thanks Chris Share this post Link to post Share on other sites
