We have installed a 16 Channel (Allimex 1610) DVR for one of the bank , it been working for last 1 year very well no complaints. but a few months back we received a call that DVR is not working. When we went and checked that DVR is bringing a message ( file System Broken) when its detects Hdd. when i we go to the HDD setup it even asks for format.(but we didn't format) as the DVR is for the Bank there is impotent footage which needs to be backed up. What I need to know as the DVR comes with Unknown file format , is i format and try for DATA recovery will it work?? if it works what are instructions? Can any please help me with this Issue ..I'll be very great full.
