it works very good. if i unplug from power few seconds and turn it on it keeps the time and date. but if i let it 10 min without power it resets the time. the system log list is empty. so i don`t know if this is good or not. i`ve putted now a 250Gb Western Digital Hdd, i hope it will last long time. i have the system from 2 years past, and i think i was lucky to have this HDD working such time. Because i saw dvr sistems wich crashed in 6 monts and all have HDD problems. I reminded that i saw an error at one DVR with HDD in rack ... " HDD DMA error " or something like that and i dont know what it mean. And i dont know what seems to be the problem: the HDD, rack, IDE cord, ... i dont know SO i`m glad i recived advices from u, i really learnt a lot from u ! Have a good day/night! (i`m from Romania BTW and now here is night) Thanks again, verry much !!

i`ve changed the HDD and i tested it for half a day....it worked ok. i could watch the recording data and i even could connect on lan with video server e, and download some data. the old hdd didn`t let me download it said "DVR doesen't contain any data" I watched on the motherboard and i couldn't see any battery u spoken to me. if it's under the MB, i think it isn't, then i didn't watch there. How long generally last the time and date until it resets without having any power from 220v ? Thx for your help! I even managed to understant the system log with all that errors have a good day and be blessed !!!

Hello !! I have an AVC 760z for long time ago, about 2 years and a half, and now i have some problems with it. Something was stolen from my place and i wanted to look on the recording to see what happened and i saw that the recording list was messed-up. It recorded one part of day and suddenly date and time changed (from 16-sep-2009 to 01-jan-2000) and te recording was (2009-sep-16 10:20:31 2009-sep-16 10:29:07......etc... 2009-sep-16 11:54:02 2000-jan-01 00:00:01 2000-jan-01 00:08:04 2000-jan-01 00:10:25 2000-jan-01 00:00:01) just like it was continuous resetting. i dont know what is the problem and another problem i have that when i want to look at a recording suddenly it freeze and displays "Disk scanning". The HDD has never been changed. So please if someone have some answers i would be glad if helps me !!! Wish a good day to all !![/b]
