i'm using DVG 2004-DS ASTELLO PAL 4CH dvr system, i used 500gb hdd sata inside. after i recorded video for 2 weeks, i want to playback the video from my pc. so i connect the hdd from dvr and connected it to pc. but hdd not detected in windows explorer. but it detected from diskmanagement. but still it cant detect any new drive in explorer. help how can i backup the recorded video?? what should i do then??

oww,, well.. thank you very much for the solution,, maybe i'll just changed the dvr which have usb port,,

my DVR do not have any USB port or LAN port,, is there any software that makes windows can read the format of the hdd from dvr????
