hjuhasz 0 Posted September 12, 2013 Hello. I had a tecnitian install this Dahua DVR model dvr0804le-as. It has 5 cameras connected and sending video but the DVR isn't detecting the hard drive. It seems it did before, the HD is formatted with different FAT32 partitions and is detected properly by PC's. Does anybody know a solution? Share this post Link to post Share on other sites
tesc_cctvpro 0 Posted September 29, 2013 How many hard drives in the unit and what capacity? First thing to check is the available power - with this particular unit at around 6v the recording icons will dissapear as the drive stops spinning properly, usually at around this level the unit cannot detect the drive either. The start up power demand of a 500GB hard drive differs vastly to that of a 2TB unit. Initially these units came out with 2A power supplies and as the Hard Drive capacities increased, so did the stock power supply capacity - I think they are currently shipped with 5A units. If you are using anything other than the stock power supply or larger capacity drive than the unit supports - the most common cause of this problem is that the dvr is not getting enough power to get the hard drive platter to spin at it's desired RPM. Use a larger capacity power supply unit, and see if that sorts out the problem --- ordinarily this problem is associated with the no hard drive beep at startup.
