hi
i am facing a problem with old records,
problem started when i planned to upgrade the hard drive on my dvr, i removed the old one and install bigger size hdd, but unfortunately i needed to get some records from old hdd, when i connected back to same dvr it is showing no record, how i can get the records? and is there a problem removing the hdd from dvr?
i did not format the old hdd, i just switched off the dvr and removed the hdd then i kept it in a safe place
